Hawaii isn’t just about sun-kissed beaches and mai tais. Beyond the postcard-perfect shores lie emerald rainforests teeming with life and dramatic volcanic peaks offering breathtaking vistas. This article dives into the best hiking experiences Hawaii has to offer, focusing on specific trails and practical advice to make your adventure unforgettable.
Oahu: Stairway to Heaven (Haiku Stairs) and Beyond
Let’s start with Oahu. The infamous Haiku Stairs, also known as the “Stairway to Heaven,” are a legendary hike that are technically illegal due to safety concerns and ongoing repairs. While officially closed to the public and heavily monitored, it’s important to understand why it draws so many. These stairs, originally built for a WWII-era naval radio station, climb nearly 3,000 feet up the Ko’olau mountain range. Respect the law, however tempting it may be, because trespassing carries significant penalties. Always check for updated legal status with the City and County of Honolulu before planning any trip in the area.
Instead of risking the Haiku Stairs, explore the Aiea Loop Trail. This 4.8-mile loop trail on Oahu is rated moderate and known for its beautiful views, lush greenery, and relatively easy accessibility. It’s a fantastic introduction to Hawaiian rainforest hiking. You’ll find access from Aiea, Oahu, at the end of Aiea Heights Drive. The trail is free to access and well-maintained. Plan for about 3-4 hours to complete the loop. Pack plenty of water, as the humidity is high even on cooler days. Look out for native birds like the ‘iwa, one of Hawaii’s forest birds.
For panoramic coastal views on O’ahu, consider the Makapu’u Point Lighthouse Trail. It’s a 2-mile round trip and paved, making it a comfortable hike for families with children. The trail is free and provides views of the Koko Crater, Rabbit Island and, during whale season (November to May), you might even spot humpback whales breaching. This hike is very exposed, so wear sunscreen and a hat. Start early in the morning to avoid the midday heat. Parking at the trailhead can get crowded, especially on weekends, so arriving early is also recommended.
Another popular, but more challenging, hike on Oahu is the Diamond Head Summit Trail. It’s a 1.6-mile round trip that climbs to the summit of a volcanic tuff cone. While relatively short, the trail includes steep stairs and uneven surfaces. The entrance fee to Diamond Head State Monument is approximately $5 per vehicle or $1 per person for walk-ins. Reservations are now required for entry to the park, so be sure to book your time slot online in advance at the official park website. The views from the summit are stunning, offering panoramic vistas of Waikiki and the surrounding coastline. Bring water and wear comfortable shoes, as the trail can be hot and crowded.
Maui: Haleakala’s Summit and the Road to Hana Waterfalls
Maui offers a diverse range of hiking experiences, from otherworldly volcanic landscapes to lush rainforests. A visit to Haleakala National Park is a must. Hiking within the Haleakala Crater is an unforgettable experience. The Sliding Sands Trail is a popular option, descending into the heart of the crater. Be aware that altitude sickness is a real concern at this elevation (over 10,000 feet), so acclimatize gradually and drink plenty of water. The trail is strenuous since the altitude can challenge even experienced hikers. The park entrance fee is approximately $30 per vehicle and is valid for three days. If you plan to return often, consider purchasing the America the Beautiful Pass, which grants access to all national parks for a year.
If you’re an experienced hiker, you might consider the Halemau’u Trail. It starts at the Halemau’u parking lot and has a much better descent grade coming down versus going up. Another option at Haleakala National Park is to hike the shorter Pa Ka’oao (White Hill) Trail. This is a short and accessible paved loop at the summit, offering stunning views with minimal effort. It gives you fantastic panoramic views and is perfect if you’re short on time or have limited mobility. Consider purchasing the National Park Annual Pass if you plan on visiting several national parks within a year.
For a rainforest adventure, drive the legendary Road to Hana. This winding road is famous for its scenic beauty and stunning waterfalls. Several hiking trails lead to hidden waterfalls. One popular option is the Pipiwai Trail in Haleakala National Park’s Kipahulu District. This 4-mile round trip hike leads to the majestic Waimoku Falls, passing through a bamboo forest along the way. The trail is generally well-maintained, but be prepared for muddy conditions after rain. Allow ample time for the Road to Hana as it takes the entire day to drive the full loop.
The Twin Falls hike, located near mile marker #2 on the Road to Hana, is a popular and relatively easy option for waterfall viewing. Note that this is on private land, and there is sometimes a small fee for parking and access. The hike leads to several smaller waterfalls and swimming holes. Before heading to Twin Falls, it is always a good idea to check current access status. Use caution when swimming in the pools, as flash floods can occur.
Kauai: The Na Pali Coast and Waimea Canyon
Kauai, known as the “Garden Isle,” is a hiker’s paradise. The majestic Na Pali Coast offers some of the most spectacular hikes in Hawaii. The Kalalau Trail is a challenging 11-mile (one way) hike along the Na Pali Coast, requiring permits for overnight camping. This hike is not for the faint of heart, as it involves steep climbs, stream crossings, and exposure to cliffs. Permits are required for camping or day hiking beyond Hanakapiai Valley. The Kalalau Trail gives you stunning scenery but should only be attempted by experienced hikers.
For a shorter, less strenuous taste of the Na Pali Coast, hike to Hanakapiai Falls. This 8-mile round trip hike follows the first two segments of the Kalalau Trail, leading to a beautiful waterfall. You’ll need to obtain permits and make reservations in advance with the Division of State Parks. Even this shorter hike requires a good level of fitness and includes stream crossings and rocky terrain. Be sure to check current trail conditions and any advisories before setting out.
For views of the iconic Na Pali coast without the demanding hike, consider visiting the overlook at Kokee State Park. The view is breathtaking. Another option on Kauai is exploring Waimea Canyon, known as the “Grand Canyon of the Pacific”. Several hiking trails offer stunning views of the canyon. The Canyon Trail is a 3.4-mile scenic hike to Waipo’o Falls with beautiful canyon and waterfall views. Make sure you pack your camera to capture the vibrant colors of the canyon walls.
Another iconic spot for viewing Waimea Canyon is the Pu’u Hinahina Lookout. This is easily accessible and offers panoramic canyon views. This is a great place to get a sense of scale and grandeur of this geological marvel. It’s a fantastic option for those who prefer not to hike but still want to experience the beauty of Waimea Canyon.
Big Island: Volcanoes National Park and Lush Valleys
The Big Island, also known as Hawai’i Island, offers diverse landscapes, from active volcanoes to lush valleys. Volcanoes National Park is a must-visit for any hiker on the Big Island. Hike across solidified lava flows, explore steaming vents, and witness the power of volcanic activity. The Kilauea Iki Trail is a popular 4-mile loop hike that descends into the Kilauea Iki crater, offering a unique opportunity to walk across the crater floor. The trail is well-marked but can be hot and exposed, so bring plenty of water and wear sunscreen. Check the park’s website at nps.gov/havo for current conditions and any closures before heading out.
The Thurston Lava Tube (Nāhuku) is another popular attraction in Volcanoes National Park. It’s a short, easy walk through a lava tube formed centuries ago. It’s a fascinating geological formation. Keep an eye out for native birds and interesting plant life along the trail. Since this is inside Volcanoes National Park, plan your visit to align with the park entrance fee schedule.
For a completely different experience, head to the Pololu Valley Lookout. This dramatic overlook provides stunning views of the coastline and the black sand beach below. A steep trail leads down to the beach. Another great hiking spot is Waipio Valley, it offers a challenging but rewarding hike down to a beautiful black sand beach fringed by towering cliffs. The road down to the valley is very steep and requires vehicles with 4-wheel drive. If you don’t have a suitable vehicle, you can hike down but be prepared for a strenuous climb back up.
Close to Volcanoes National Park, you can explore the Puna Coastline. Drive Chain of Craters Road and explore the jagged coast line that resulted from the recent lava flows into the ocean. Hike around the trails that hug the coast to observe the rugged beauty of the black lava cliffs and the vibrant blue ocean. Respect all posted closures and take precautions to avoid any dangerous areas.
Essential Hiking Tips for Hawaii
Hiking in Hawaii can be challenging due to the climate, terrain, and unique environmental factors. Here are some essential tips to ensure a safe and enjoyable experience:
- Check the Weather: Hawaiian weather can change rapidly. Check the forecast before you go and be prepared for rain, even on sunny days.
- Pack Appropriately: Wear sturdy hiking shoes with good traction. Pack plenty of water, sunscreen, a hat, and insect repellent. Consider bringing a light rain jacket.
- Stay on Marked Trails: Stick to marked trails to avoid getting lost and to protect the fragile ecosystem.
- Respect Wildlife: Observe wildlife from a distance and never feed them.
- Be Aware of Hazards: Be aware of potential hazards such as flash floods, landslides, and falling rocks.
- Inform Someone: Let someone know your hiking plans and expected return time.
- Leave No Trace: Pack out everything you pack in and leave the environment as you found it.
- Respect Local Culture: Be respectful of local customs and traditions. Ask for permission before entering private property. Note that some areas may be considered sacred.
Flash Floods: This is a real danger, especially in valleys and near streams. Even if it’s not raining where you are, heavy rain in the mountains can cause flash floods downstream. Pay attention to weather conditions and never attempt to cross flooded streams.
Sun Protection: The Hawaiian sun is intense. Use sunscreen with a high SPF, wear a hat, and consider wearing long sleeves and pants to protect your skin.
Hydration: Drink plenty of water, especially on longer hikes. Carry more water than you think you’ll need, as dehydration can set in quickly in the humid climate.
Footwear: Wear sturdy hiking shoes with good traction. The trails can be muddy, rocky, and uneven. Sandals or flip-flops are not appropriate for most hiking trails.
Insects: Mosquitoes and other insects can be a nuisance, especially in rainforest areas. Use insect repellent to protect yourself from bites.
Trail Etiquette: Yield to uphill hikers. Step aside to let others pass. Keep noise levels to a minimum to respect other hikers and the natural environment.
Best Time to Hike in Hawaii
The best time to hike in Hawaii depends on the island and the specific trail. Generally, the shoulder seasons (April-May and September-October) offer pleasant weather with fewer crowds. Summers (June-August) can be hot and humid, while winters (November-March) can be rainy, especially on the north and east sides of the islands. Always check local weather forecasts and trail conditions before heading out, regardless of the time of year.
Cost Considerations
Hiking in Hawaii can be relatively inexpensive, especially if you focus on free trails. However, some costs to consider include:
- Park Entrance Fees: Some national and state parks charge entrance fees, typically around $30 per vehicle.
- Permits: Permits are required for some hikes, especially those involving camping or access to restricted areas like the Kalalau Trail.
- Accommodation: If you’re planning multi-day hikes, you’ll need to factor in the cost of accommodation, which can range from camping fees to hotel stays.
- Transportation: Getting to and from trailheads can involve rental car costs or the expense of guided tours.
- Gear: Depending on the hike, you may need to purchase or rent hiking gear, such as backpacks, hiking poles, or waterproof clothing.
Ethical Considerations
Responsible tourism and ethical hiking are crucial for preserving Hawaii’s natural beauty and cultural heritage. When hiking in Hawaii, keep the following in mind:
- Respect the ‘aina (land): Treat the land with respect and avoid damaging or disturbing natural features.
- Support local businesses: Patronize local restaurants, shops, and tour operators.
- Learn about Hawaiian culture: Take the time to learn about Hawaiian history, traditions, and values.
