The Big Island of Hawaii is a paradise for waterfall lovers! Forget crowded beaches for a day and lace up your hiking boots to discover hidden cascades and lush rainforest scenery. This guide will take you off the beaten path to some of the most stunning waterfalls the island has to offer, providing you with all the details you need to plan your own unforgettable adventure.

Choosing Your Waterfall Adventure: Tailoring the Hike to Your Needs

Before diving into specific waterfalls, let’s talk about choosing the right hike for you. Not all waterfall hikes are created equal. Some are short, easy strolls perfect for families, while others are challenging treks for seasoned adventurers. Consider these factors:

• Fitness Level: Be honest with yourself! If you haven’t hiked in a while, start with an easier trail.
• Time: How much time do you have? Some hikes can take half a day or longer.
• Accessibility: Are you looking for a paved path or a rugged, muddy trail?
• Crowd Tolerance: Some waterfalls are very popular, especially during peak season. If you prefer solitude, seek out lesser-known spots.

Waterfall Hikes for Beginners and Families

If you’re new to hiking or traveling with kids, these options are gentle and rewarding:

Akaka Falls State Park

This is probably the most famous and accessible waterfall on the Big Island. The park itself is a short, paved loop trail (only about 0.4 miles!) that takes you past not one, but two waterfalls: Akaka Falls and Kahuna Falls. Akaka Falls plunges an impressive 442 feet, making it a truly spectacular sight. Kahuna Falls is smaller but still beautiful.

Directions: Located off Highway 220, about 11 miles north of Hilo. Just follow the signs!
Cost: There is a fee for parking, typically around $5 per vehicle for non-residents, and a $1 per person entrance fee.
Tips: Go early in the morning to avoid crowds. The trail can be slippery after rain, so wear appropriate shoes. No swimming here.

Rainbow Falls

Located right in Hilo, Rainbow Falls is incredibly easy to access. You can view the waterfall from a convenient viewing platform, making it ideal for those with limited mobility or time. The falls are particularly beautiful in the morning when the rising sun creates rainbows in the mist. While there’s no “hiking” required in the traditional sense, you can explore the surrounding banyan trees and lush vegetation.

Directions: Take Waianuenue Avenue in Hilo until you reach Rainbow Drive. It’s well-marked.
Cost: Free!
Tips: Visit early for the best chance of seeing a rainbow. Swimming is not recommended due to swift currents and potential for leptospirosis.

Moderate Waterfall Hikes for the Adventurous

These hikes offer a bit more of a challenge but are still manageable for most people with a reasonable level of fitness:

Umauma Falls

Umauma Falls is on private property, so you’ll need to book a tour to see it. However, the experience is worth it! The tour often includes ziplining over the falls, which is an exhilarating way to see the Big Island’s beauty. Alternatively, adventurous souls can often kayak to the falls, providing a unique perspective. The hike to the base of the falls is of mild difficulty.

Directions: Most tours depart from locations near Hilo. Check with the tour operator for specific instructions.
Cost: Tour prices vary depending on the package. Expect to pay around $150+ for a ziplining tour, roughly $80 for access to a hike and swim.
Tips: Book your tour in advance, especially during peak season. Wear comfortable clothing and shoes that can get wet.

Peepee Falls (Boiling Pots)

Peepee Falls, also often know as Boiling Pots, is another site along the Wailuku River. While not exactly a “hike”, the viewpoint to see it requires a short walk on an easy trail. Due to the unique rock formations, the water appears to be boiling when the river is flowing strong. While this is a popular sightseeing stop, you often see locals swimming when the water has calmed, but be aware of flash flood potential here!

Directions: Located off Waianuenue Avenue in Hilo, near Rainbow Falls.
Cost: Free!
Tips: Best viewed after heavy rainfall when the river is flowing strongly. Swimming is generally discouraged, especially during high water levels.

Challenging Waterfall Hikes for Experienced Hikers

These hikes require a higher level of fitness, good hiking boots, and often involve navigating uneven terrain and potentially hazardous conditions:

Hi’ilawe Falls (Waipi’o Valley)

Reaching the base of Hi’ilawe Falls, once thought to be the tallest waterfall in the state, is no small feat. It involves traversing the rugged Waipi’o Valley, often referred to as the “Valley of the Kings”. You can hike down into the valley (a steep and challenging descent), take a shuttle, or ride in a 4×4 vehicle. You’ll then need to hike or kayak up the valley floor to reach the falls. The hike can be muddy and slippery, and the river crossings can be challenging. Hi’ilawe Falls is on private property, so it may require special permissions or guided tours. If there has been recent dry conditions, the waterfalls may not be flowing.

Directions: Drive to the Waipi’o Valley Lookout near the end of Highway 240. The trailhead down into the valley is located there.
Cost: Shuttle services typically charge around $60-80 per person. Guided tours can cost significantly more.
Tips: This hike is not for beginners. Be prepared for a full day of hiking and bring plenty of water and snacks. Check the weather forecast before you go, and be aware of potential flash floods. Respect the local community and their ancestral lands.

Sacred Falls (Kohala)

Heads up: This hike is officially closed and highly discouraged. Attempting it is dangerous and could result in serious injury or even death. However, it is a waterfall so significant that it warrants mentioning. The trail is overgrown, unmaintained, and prone to flash floods. The rock formations are unstable, making it a risky climb up the watershed. Ignoring the closures endangers yourself and any potential rescue workers.

Directions: Access is discouraged.
Cost: The cost is your life.
Tips: Seek alternative waterfall experiences.

What to Pack for Your Waterfall Hike: A Checklist

Being prepared is essential for a safe and enjoyable hike. Here’s a checklist of essential items:

• Hiking Boots: Sturdy, waterproof hiking boots with good traction are a must.
• Water: Bring plenty of water, especially on longer hikes. A hydration pack is a great option.
• Snacks: Pack energy bars, trail mix, fruit, or other snacks to keep you fueled.
• Sunscreen: The Hawaiian sun is intense, even on cloudy days.
• Insect Repellent: Mosquitoes and other bugs can be annoying, especially near waterfalls.
• Rain Gear: Rain showers are common on the Big Island, so bring a raincoat or poncho.
• First-Aid Kit: A small first-aid kit should include bandages, antiseptic wipes, pain relievers, and any personal medications.
• Swimsuit and Towel: If you plan on swimming in the waterfall pool, don’t forget your swimsuit and a quick-drying towel.
• Dry Bag: Protect your electronics and other valuables from water damage.
• Camera: Capture the beauty of the waterfalls!
• Map and Compass/GPS: While many trails are well-marked, it’s always a good idea to have a map and compass or GPS, especially on more remote hikes.

Safety Tips for Waterfall Hiking: Stay Alert and Aware

Your safety is the top priority. Here are some important safety tips to keep in mind:

• Check the Weather Forecast: Avoid hiking during heavy rain or periods of flash flood warnings.
• Stay on Marked Trails: Don’t wander off the trail, as this can lead to getting lost or injured.
• Be Aware of Flash Floods: Water levels can rise rapidly in streams and rivers, especially after heavy rain. If you hear a sudden increase in water flow, seek higher ground immediately.
• Watch Your Step: Trails can be uneven, slippery, and muddy. Pay attention to your footing and take your time.
• Let Someone Know Your Plans: Tell a friend or family member where you’re going and when you expect to be back.
• Hike with a Buddy: Hiking with a partner is always safer than hiking alone.
• Respect the Environment: Pack out everything you pack in, and avoid disturbing the natural surroundings.
• Be Aware of Leptospirosis: Leptospirosis is a bacterial disease that can be contracted through contact with contaminated water. Avoid swimming in areas with stagnant water or where animals may have urinated.

Beyond the Waterfalls: Exploring the Big Island’s Natural Beauty

While the waterfalls are undoubtedly a highlight, the Big Island has so much more to offer. Consider exploring these other natural attractions:

• Hawaii Volcanoes National Park: Witness the power of active volcanoes and hike through lava landscapes.
• Mauna Kea: Visit the summit of Mauna Kea, a dormant volcano and home to world-class astronomical observatories.
• Punalu’u Black Sand Beach: See endangered Hawaiian green sea turtles basking on the black sand.
• Waipio Valley: Experience the natural charm of a culturally significant valley framed by towering cliffs

Don’t just chase waterfalls; immerse yourself in the island’s diverse ecosystems and cultural richness.

Treating Water for Drinking

While the allure of pristine waterfall water is strong, it’s crucial to remember that untreated water sources can harbor harmful bacteria, viruses, and parasites. To safeguard your health, always treat water before drinking it. Here are a few reliable methods:

• Boiling: This is the most effective method. Bring the water to a rolling boil for at least one minute (three minutes at higher altitudes).
• Water Filters: Portable water filters are a convenient option. Look for filters with a pore size of 0.2 microns or smaller to remove most bacteria and protozoa. Brands like Sawyer and LifeStraw are popular choices.
• Water Purification Tablets or Drops: These solutions typically contain chlorine dioxide or iodine, which kill harmful microorganisms. Follow the instructions carefully and allow sufficient contact time for the purification process to be effective.

Even if the water looks crystal clear, it’s always best to err on the side of caution and treat it. Staying hydrated is essential for a successful hike, but staying healthy is even more important.

Respecting Local Culture and Traditions

The Big Island of Hawaii is not just a tourist destination; it’s a place with a rich cultural heritage and deep connection to the land. As visitors, it’s essential to be respectful of local customs and traditions.

• Ask Permission Before Entering Private Property: Many waterfalls are located on private land. Always seek permission before entering.
• Be Quiet and Respectful in Sacred Sites: Some waterfalls and surrounding areas may be considered sacred sites by the local Hawaiian community. Be mindful of your behavior and avoid loud noises or disruptive activities.
• Dress Modestly: When visiting temples or other cultural sites, dress modestly and avoid wearing revealing clothing.
• Learn a Few Basic Hawaiian Phrases: Showing an effort to learn the local language goes a long way. “Aloha” (hello/goodbye/love) and “Mahalo” (thank you) are good starting points.
• Support Local Businesses: Choose to eat at local restaurants and buy souvenirs from local artisans. This helps support the local economy and preserve traditional craftsmanship.

By being a respectful and responsible visitor, you contribute to the preservation of Hawaii’s unique cultural heritage.
