Forget luaus and Waikiki Beach for a second. Hawaii has so much more to offer than the typical tourist traps. We’re talking secret waterfalls, hidden lava tubes, and local experiences that’ll make you feel like you’ve truly connected with the islands. This guide will take you off the beaten path and introduce you to the unforgettable “hidden gems” of Hawaii, focusing on unique activities. Get ready to ditch the crowds and dive into the real Hawaii!
Hiking to the Papakolea Green Sand Beach (Big Island)
Imagine walking across volcanic landscapes to reach a beach with shimmering green sand. Papakolea, also known as Green Sand Beach, on the Big Island, is one of only four green sand beaches in the world! The green hue comes from olivine crystals, a silicate mineral, formed during a volcanic eruption.
Getting There: The drive to the trailhead is rough. A 4-wheel drive vehicle is highly recommended (rental companies often prohibit off-roading, so proceed with caution). The trailhead is located near South Point (Ka Lae). From Highway 11, turn onto South Point Road and continue for about 10 miles. If you don’t have a 4×4, local residents offer shuttle services for a fee (usually around $20 per person roundtrip). This is a common way to get to the beach and supports the local community. The walk is approximately 2.5 miles each way along a coastline path. Be prepared for a hot, windy, and potentially dusty hike across fairly flat, exposed terrain.
What to Bring: Plenty of water (at least 2 liters per person), sunscreen, a hat, sturdy shoes, and a towel. There’s no shade, so be prepared for full sun exposure. Snorkeling gear isn’t a bad idea, as the water is usually clear.
What to Expect: The hike can be challenging, especially in the heat. But the reward is well worth it. The green sand is unbelievably gorgeous, and the surrounding cliffs are dramatic and sculpted by the ocean. Swimming can be tricky due to the strong currents, so be cautious. Be respectful of the environment and pack out everything you pack in. Touching or removing the green sand is not permitted and could alter the beach’s composition.
Exploring the Kaumana Caves (Big Island)
Trade the beach for a subterranean adventure and explore the Kaumana Caves, a lava tube formed by a 1881 lava flow from Mauna Loa. These caves provide a glimpse into the raw power of the islands’ volcanic activity.
Getting There: The caves are located just outside of Hilo. From Hilo, take Kaumana Drive (Route 190) west for about 3.6 miles. You’ll see a sign for the Kaumana Caves State Park on the right. There is a parking lot and a platform overlooking the gaping entrance.
What to Bring: This is crucial: bring multiple sources of light! Headlamps are ideal, but flashlights will work too. The caves are pitch-black, and some areas can be slippery. Wear closed-toe shoes and clothes you don’t mind getting dirty. A light jacket is also good because it can be cool inside. Gloves can be helpful for gripping the rocks.
What to Expect: The main entrance is wide and easy to access, leading into a large cavern. You can explore a considerable distance into the cave, but be aware that it gets darker, smaller, and more challenging the further you go. Exercise caution and don’t attempt to go too far if you’re not experienced with caving. Lava tubes can be unstable, so be mindful of falling rocks. The sounds of dripping water echo through the caverns, creating an eerie and adventurous atmosphere. The Kaumana Caves are a free activity.
Snorkeling at Two Steps (Big Island)
Forget overcrowded beaches, Two Steps, near Honaunau, is known for its fantastic snorkeling and diving in a historically important area near Pu’uhonua o Honaunau National Historical Park. The easy access point (two natural “steps” leading into the water) makes it perfect for all skill levels.
Getting There: From Kona, take Highway 11 south to Honaunau. Turn right onto Pu’uhonua Road and follow it to the end. There’s a small parking lot, which fills up quickly, so arrive early. Parking can sometimes be a challenge, so be prepared to walk a bit.
What to Bring: Your snorkeling gear (mask, snorkel, fins). If you don’t have your own, you can rent it from shops in Kona or near the site. Reef-safe sunscreen is a must to protect the coral. A towel, water, and snacks are also recommended.
What to Expect: The water is usually crystal clear, with excellent visibility. You’ll see a vibrant reef teeming with colorful fish, sea turtles, and other marine life. The area is a protected marine reserve, so the fish are abundant and unafraid. The two “steps” make entering and exiting the water easy, even for beginners. Be aware of boat traffic and stay within the designated snorkeling area. Respect the marine environment and avoid touching or disturbing the coral or sea creatures. The snorkeling is free, but there is a small entrance fee to the Pu’uhonua o Honaunau National Historical Park if you want to explore the historical site afterwards.
Kayaking the Wailua River to the Fern Grotto (Kauai)
Trade the crowds for a quiet paddle towards a natural amphitheater draped in ferns. Kayaking (or canoeing) up the Wailua River is a classic Kauai experience, and the Fern Grotto is the perfect destination. There are two ways to approach this experience: you can rent a kayak and paddle yourself, or you can take a guided boat tour.
Kayaking on Your Own: Rent kayaks from various outfitters near the Wailua River State Park. A double kayak typically costs around $50-$75 for a half-day rental. Paddle up the South Fork of the Wailua River. The paddle to the Fern Grotto is about 2 miles each way and takes roughly 45 minutes to an hour, depending on your pace. Once you reach the designated landing area, you’ll take a short, easy walk to the Fern Grotto. Previously, you were able to go inside the grotto, but following a rockslide, the grotto is only accessible to view from a wooden platform.
Taking a Guided Boat Tour: Smith Family Garden Luau offers boat tours to the Fern Grotto. These tours are motor-driven and often include Hawaiian music and storytelling. Costs are approximately $30-$40 per person.
What to Bring: Water, sunscreen, a hat, water shoes, and a waterproof bag for your valuables. If you’re kayaking, bring a dry bag for your phone and camera.
What to Expect: The Wailua River is calm and peaceful, perfect for a leisurely paddle. The scenery is lush and green, with tropical vegetation lining the riverbanks. The Fern Grotto is a unique and beautiful natural wonder. Whether you kayak yourself or take a guided tour, the Wailua River and Fern Grotto is a “must do” while on the island of Kauai.
Swimming in Queen’s Bath (Kauai)
This natural tide pool is a stunning spot. Queen’s Bath is a unique geological formation, a sinkhole created by volcanic rock that has been carved out over time by the ocean’s relentless pounding. Sheltered from the open ocean, it is filled with seawater and marine life, creating a natural swimming pool. However, it’s essential to understand the dangers and exercise extreme caution.
Getting There: Queen’s Bath is located in Princeville on Kauai’s North Shore. Navigate to the end of Kapiolani Road in Princeville. There is a residential area at the end, so be respectful of the community. The trail to Queen’s Bath begins nearby. It’s a somewhat slippery and rocky 10-15 minute downhill hike to the pools.
Safety First: Queen’s Bath is beautiful but can be extremely dangerous, especially during high surf or rough conditions. Strong currents, unpredictable waves, and slippery rocks have caused numerous injuries and fatalities. Never enter Queen’s Bath if the surf is up. Check the local surf report and heed all warning signs. Observe the pool from a distance before entering to assess the conditions. Only swim during calm conditions when the tide is low.
What to Bring: Sturdy shoes for the hike, reef-safe sunscreen, water, and a towel. Water shoes are helpful for navigating the slippery rocks. A dry bag is a good idea for your valuables.
What to Expect: Queen’s Bath is a gorgeous natural pool filled with marine life, including fish, sea urchins, and occasionally sea turtles. You can swim and snorkel in the pool, but be mindful of the sharp rocks and potential currents. If the water is rough or the waves are crashing, do not go near the pool. Observe proper etiquette and be respectful of the area. The trail to Queen’s Bath is free to access.
Discovering the Nakalele Blowhole (Maui)
Prepare to be amazed by the power of nature. The Nakalele Blowhole is a geyser-like phenomenon on Maui’s northern coast. As waves crash against the shoreline, water is forced through an underwater opening in the lava rocks, erupting high into the air in a spectacular display.
Getting There: The blowhole is located along the rugged northern coastline of Maui, along Highway 30 (the Kahekili Highway). It’s about a 30-45 minute drive north of Kapalua. There are pull-off areas along the highway where you can park. Be careful driving this road, as it is narrow and winding.
Safety First: The Nakalele Blowhole is a powerful natural attraction, but it can be dangerous. Stay a safe distance away from the blowhole. The area around the blowhole can be slippery and unstable. Never approach the blowhole, especially when the surf is high. Unpredictable surges of water can occur, posing a serious risk. Also, be respectful of the natural environment and stay on designated paths.
What to Bring: Sturdy shoes are recommended for walking on the rocky terrain. Bring water, sunscreen, and a hat. A camera is a must to capture the dramatic eruptions.
What to Expect: The Nakalele Blowhole can shoot water over 100 feet into the air, creating a truly impressive sight. When the surf is high, the eruptions are even more dramatic. The surrounding landscape is equally stunning.
Road to Hana Must-Stops (Maui) – Beyond the Waterfalls
The Road to Hana is a legendary drive, but many people stick to the well-known waterfalls. While they are beautiful, there are many other hidden gems to discover along the way.
The Garden of Eden Arboretum & Botanical Garden (Mile Marker 10.5): This botanical garden is worth the entrance fee. It’s a privately-owned arboretum and special events location at mile marker 10.5. With over 700 botanical varieties, the Garden of Eden is one of the most elaborate botanical gardens on Maui, and one of the most beautiful stops on the Road to Hana. There is a small fee, about $15 per adult.
Waianapanapa State Park (Black Sand Beach) (Mile Marker 32): This is not exactly a secret, but it’s consistently rated as one of the best places in Hawaii. Pre-planning is a must for this site; reservations are required for entry for daytime access to the park.
Hamoa Beach (Near Hana Town): This beautiful grey sand beach, located just north of Hana, is often overlooked by tourists rushing to get to the Pools of Ohe’o (Seven Sacred Pools). It can be difficult to find, but it’s worth the effort.
Pools of Ohe’o (Seven Sacred Pools) (at the Kīpahulu District of Haleakalā National Park): Now officially open to the public. There are no waterfalls entering the pools, and the falls have not flowed into the pools for many years. You won’t be able to swim in the pools. To enter Kīpahulu District, you will need a valid park entrance pass or America the Beautiful Pass. It’s $30 per vehicle, good for 3 days if you want to also visit the summit.
What to Bring: The Road to Hana can be rainy and muddy, so bring appropriate footwear and a rain jacket. Snacks, water, and sunscreen are essential. Bring cash for roadside fruit stands and other small businesses.
What to Expect: Be prepared for a full day of driving. The road is winding and narrow, and traffic can be slow. Allow plenty of time to explore the sights along the way. Respect the local residents and drive safely.
Pearl Harbor Alternative: USS Bowfin Submarine Museum & Park (Oahu)
While the USS Arizona Memorial is a must-see at Pearl Harbor, consider a visit to the USS Bowfin Submarine Museum & Park for a deeper dive into naval history, both literally and figuratively. This hidden gem offers a more intimate and hands-on experience.
What it is: The USS Bowfin (SS-287) is a World War II fleet submarine that earned 13 battle stars for its service in the Pacific. Today, it’s a museum ship docked next to the Pearl Harbor Visitor Center. You can actually go inside the submarine and experience what life was like for the crew.
What to Expect: Walking through the narrow corridors and cramped living quarters of the USS Bowfin is a very immersive experience. Audio guides are available that will walk you through the vessel, explaining the role of each compartment and the daily life of the crew.
Cost and Hours: Admission to the USS Bowfin Submarine Museum & Park is around $20 for adults and $12 for children (prices subject to change). Check their website (bowfin.org) for current hours of operation.
Tips: The interior of the submarine is tight, so those with claustrophobia might find it challenging. Be prepared to climb ladders and duck through doorways. Allow at least one to two hours to fully explore the submarine and the museum.
Off the Beaten Path: Kaena Point State Park (Oahu)
Escape the city and experience Oahu’s wild West Side at Kaena Point State Park. This remote and rugged area offers stunning coastal scenery, hiking trails, and the chance to see Hawaiian monk seals and seabirds. This is one of the last intact dune ecosystems on the island.
Getting Here: Kaena Point is located at the westernmost tip of Oahu. You can access it from either the North Shore (via Waialua) or the Leeward Coast (via Makaha). Important: the road beyond the paved section requires a 4-wheel drive vehicle. If you don’t have a 4×4, you can park at the end of the paved road and hike the rest of the way (about 2.5 miles each way).
What to See and Do: Hiking is the main activity at Kaena Point. The coastal trail offers breathtaking views of the ocean and the dramatic coastline. The hike is fairly flat but can be hot and exposed, so bring plenty of water and sunscreen. Keep an eye out for Hawaiian monk seals basking on the beaches and seabirds nesting in the dunes.
Important Caveats: Kaena Point can be hot and windy, so dress accordingly. There is very little shade, so be prepared for full sun exposure. Respect the wildlife and keep a safe distance from the monk seals. The area can be dangerous during high surf, so be aware of the conditions.
Bonus: It’s considered a sacred place in Hawaiian culture and is believed to be the point where souls depart into the afterlife.
Stargazing on Mauna Kea (Big Island)
Mauna Kea, meaning “white mountain”, on the Big Island is known as one of the best stargazing locations on Earth. The summit of Mauna Kea is nearly 14,000 feet above sea level, placing it above most of the Earth’s atmosphere.
Driving to the summit: Visitors can drive to the summit after visiting the Visitor Information Station. However, the last several miles require a 4-wheel drive vehicle to navigate a steep, unpaved road. Many rental car companies won’t cover damage incurred on this route, so check your rental agreement carefully.
Visiting the Visitor Information Station: If you don’t have a 4-wheel drive vehicle or if you’d rather skip the high altitude drive, you can still enjoy stargazing at the Mauna Kea Visitor Information Station (VIS) at an elevation of 9,200 feet.
What to Bring: Warm clothing is important. Temperatures on Mauna Kea can drop below freezing, even in summer. Bring layers, including a jacket, hat, and gloves. Closed-toe shows are also recommended.
Altitude Sickness: The high altitude can cause altitude sickness. Spend at least 30 minutes at the Visitor Information Station (VIS) to acclimatize before ascending to the summit. Drink plenty of water and avoid strenuous activity. If you start to feel symptoms of altitude sickness (headache, dizziness, nausea), descend to a lower altitude immediately.
Safety precautions: All wheel drive vehicles and low gears are recommended. Brakes can overheat on descent from the summit. Never descend in neutral and use 4-low to allow for engine breaking.
Island Hopping by Ferry
Want to experience more than one island without the hassle of airports? While flying is the quickest way to travel between Hawaiian Islands, a less commonly known alternative is the passenger ferry.
Molokai Ferry
Operated by Molokai Ferry, runs between the Maui’s Lahaina Harbor and Kaunakakai Harbor, located in Molokai. This ferry service offers a unique opportunity to visit Molokai, an island that has retained much of its Native Hawaiian culture and offers a slower pace of life.
Things to Do on Molokai: Explore Kalaupapa National Historical Park (access restricted, requires a permit), visit Halawa Valley for a guided hike to Moaula Falls, or simply relax on the uncrowded beaches.
Things to expect: The ferry trip between Maui and Molokai is approximately 90 minutes. Check the schedule and book your tickets in advance. Molokai Ferry website provides ticket information.
Potential Future Ferry Services
Currently, there are no active ferry services that go to other islands, however, there has been talk about bringing back ferry services between the islands. So do your research and see if you can find an active ferry that’s right for you!
Attend a Traditional Hawaiian Music Jam Session (Kanikapila)
Ditch the touristy luau music shows and immerse yourself in the authentic sounds of Hawaii by attending a kanikapila. A kanikapila is an informal, impromptu Hawaiian music jam session. You’ll find locals sharing songs, stories, and good vibes. It’s a great way to experience the true spirit of aloha.
How to Find a Kanikapila: Keep an eye on local event listings in newspapers or online. Ask your hotel staff or local residents if they know of any upcoming kanikapila events. Many local restaurants and bars that showcase local Hawaiian music will often do this.
What to Expect: Kanikapila is all about sharing and having fun. Feel free to sit back, listen, and enjoy the music. If you play an instrument or sing, you might even be invited to join in! Be respectful of the musicians and the culture.
