11 Amazing Waterfalls in Oahu

Imagine a place where emerald mountains meet the sapphire sea, where the air hums with the scent of plumeria, and hidden within lush rainforests, the Earth whispers its ancient secrets through cascading water. Welcome to Oahu, Hawaii’s vibrant heart, a land not just of iconic beaches but of breathtaking, often mystical, waterfalls. You might think of Waikiki’s golden sands, but Oahu’s interior holds a wilder, wetter magic waiting to be discovered.

From easily accessible cascades perfect for families to secluded, challenging treks for the adventurous soul, this island offers a waterfall for every explorer. The best time to chase these watery wonders is typically during the wetter months from November to April, when the falls are at their most powerful and dramatic, though many flow year-round. Pack sturdy, waterproof shoes, mosquito repellent, and a sense of awe, because you are about to embark on an unforgettable journey through Oahu’s most amazing natural masterpieces. Get ready to feel the spray, hear the roar, and witness the raw beauty of Hawaii’s hidden gems.

Manoa Falls

Manoa Falls is perhaps Oahu’s most famous and accessible waterfall, drawing visitors into a world that feels straight out of a Jurassic Park movie. Nestled within a lush, misty rainforest, the hike to Manoa Falls is a relatively easy, well-maintained 1.6-mile roundtrip journey. As you walk, you’ll be enveloped by towering bamboo groves, massive fern walls, and vibrant tropical foliage, making the experience just as captivating as the destination itself.

The trail can be incredibly muddy, especially after rain, but the reward is a slender, 150-foot waterfall gracefully plunging into a shallow pool below. While swimming is strongly discouraged due to falling rocks and leptospirosis risk, the sheer beauty and tranquility of the falls make it a perfect spot for photos and quiet contemplation. This is an ideal adventure for families, couples, and solo travelers looking for a taste of Oahu’s natural beauty without an overly strenuous hike. The cool, damp air and verdant surroundings offer a refreshing escape from the island’s warmer coastal areas.

Upside-Down Waterfall

The Upside-Down Waterfall, officially known as Waipuhia Falls, is a truly unique and ephemeral natural wonder on Oahu. Unlike typical waterfalls where water cascades downwards, Waipuhia Falls defies gravity, appearing to flow upwards when strong winds hit its cliff face. This rare phenomenon occurs due to powerful trade winds pushing the water spray back up the cliff, creating an illusion of an “upside-down” cascade.

Located on the windward side of the Ko’olau Mountains, this waterfall is not a guaranteed sight and requires specific wind conditions and heavy rainfall to be active. There’s no official trail, and reaching it involves a very strenuous, often overgrown, and potentially dangerous bushwhack through dense, muddy terrain, making it suitable only for experienced and prepared hikers. If you’re an extreme adventurer seeking a truly one-of-a-kind natural spectacle that few ever witness, and you’re willing to brave the challenging conditions, this might be your ultimate Oahu quest.

Lulumahu Falls

Lulumahu Falls offers an adventurous escape into Oahu’s lush interior, providing a more rugged and less crowded experience than some of the island’s more popular trails. This beautiful 50-foot waterfall is nestled within the Honolulu Watershed Forest Reserve, and accessing it requires navigating an unmaintained trail that involves stream crossings and muddy sections. The journey itself is part of the allure, as you trek through dense bamboo forests and past a unique graffiti-covered dam, adding an unexpected urban art twist to your nature hike.

While the trail can be challenging, the reward is a serene, powerful waterfall cascading into a clear pool, perfect for cooling off after your exertion. It’s important to note that this area is technically restricted, requiring a permit from the Board of Water Supply, though many hikers proceed without one. This hike is best suited for moderately experienced hikers and those seeking a sense of discovery and solitude away from the usual tourist paths.

Likeke Falls

Likeke Falls is a hidden gem that rewards those willing to venture slightly off the beaten path, offering a relatively short but incredibly scenic hike to a beautiful multi-tiered waterfall. Located near the historic Pali Lookout, the trail descends through a dense, enchanting forest, often muddy and slippery, but manageable for most. What makes Likeke Falls unique is its serene, almost mystical atmosphere, with lush greenery and the sound of falling water creating a peaceful retreat.

There are often multiple tiers to the falls, depending on recent rainfall, with the main cascade being particularly picturesque. This hike is perfect for those seeking a quick dose of nature’s beauty without committing to a full-day trek. It’s a great spot for couples, solo adventurers, and families with older children who enjoy a bit of a challenge. Its proximity to the Pali Lookout also makes it a convenient addition to a scenic drive across the island.

Maunawili Falls

Maunawili Falls, though currently closed to the public for restoration and trail rehabilitation, has historically been one of Oahu’s most beloved and adventurous waterfall hikes. When open, it offered a vibrant journey through a tropical rainforest, crossing streams and navigating muddy paths to reach a beautiful swimming hole fed by a multi-tiered waterfall. What made Maunawili Falls truly special was the opportunity to swim in its cool, refreshing waters and even jump from a lower rock ledge (at your own risk).

The trail was known for its lush scenery, including guava trees and dense foliage, making the hike itself a memorable experience. It was a popular spot for locals and adventurous tourists alike, providing a perfect blend of exercise, natural beauty, and a refreshing dip. While it’s currently inaccessible, its future reopening will undoubtedly bring back an incredible outdoor experience for those seeking an active adventure and a rewarding swim.

Jackass Ginger Pool Falls

Jackass Ginger Pool Falls, located within the Lyon Arboretum, offers an easy and family-friendly natural escape. This small, charming waterfall cascades into a clear, shallow pool, often referred to as the “Jackass Ginger Pool” due to the abundant ginger plants in the area. The beauty of this spot lies in its accessibility and the serene environment of the arboretum.

While not a towering cascade, it provides a perfect spot for a refreshing dip on a warm day, especially popular with families and those seeking a gentle nature walk rather than a strenuous hike. The arboretum itself is a living laboratory, showcasing a vast collection of tropical plants, and the walk to the falls is a pleasant stroll through diverse botanical gardens. This attraction is ideal for families with young children, nature lovers, or anyone looking for a peaceful, low-impact outdoor activity with a delightful watery reward.

La’ie Falls

La’ie Falls is a lesser-known but rewarding waterfall hike located on the windward side of Oahu, offering a more secluded and authentic adventure. To access this trail, you must obtain a permit from Hawaii Reserves, Inc., which manages the land. This requirement helps manage crowd levels and preserves the natural integrity of the area, ensuring a more peaceful experience for those who make the effort.

The 7-mile roundtrip hike takes you through a shaded forest, following a dirt road that winds through beautiful, dense vegetation. While the trail itself is not overly steep, its length makes it a moderate challenge, and you’ll want to be prepared for muddy conditions, especially after rain. The reward is a beautiful, multi-tiered waterfall that cascades into a shallow pool, a perfect spot to relax and enjoy the tranquility away from the bustling crowds. This hike is ideal for adventurous hikers seeking solitude and a genuine connection with Oahu’s natural beauty.

Waimea Falls

Waimea Falls, nestled within the Waimea Valley, is arguably Oahu’s most family-friendly and culturally rich waterfall experience. Unlike the rugged hikes to many other falls, the path to Waimea Falls is a paved, easily accessible stroll through a stunning botanical garden. This allows visitors of all ages and abilities to enjoy the lush Hawaiian flora before reaching the magnificent 45-foot waterfall.

What sets Waimea Falls apart is not just its beauty, but the unique opportunity to swim in its natural pool. Lifeguards are on duty, and changing rooms are available, making it a safe and convenient option for a refreshing dip. Beyond the falls, Waimea Valley itself is a significant cultural site, preserving ancient Hawaiian traditions, archaeological sites, and hosting daily cultural demonstrations. This destination is perfect for families, seniors, and anyone seeking a blend of natural beauty, cultural immersion, and a refreshing swim in a controlled environment.

Kapena Falls

Kapena Falls offers an intriguing blend of urban proximity and natural allure, making it a unique stop for those seeking a more unconventional waterfall experience. Tucked away just minutes from downtown Honolulu, this waterfall is easily accessible, though finding the exact trailhead can be a bit tricky. The short, steep, and often muddy trail leads you down to a small but picturesque waterfall that cascades into a deep pool, popular with locals for swimming and cliff jumping (at your own risk).

What makes Kapena Falls truly distinctive is the presence of ancient Hawaiian petroglyphs (rock carvings) in the area, adding a historical and cultural layer to your visit. Unfortunately, the area also sees a fair amount of graffiti, which contrasts sharply with its natural beauty. This spot is best for adventurous solo travelers or groups looking for an easy-to-reach, local swimming hole with a touch of history, and who don’t mind a slightly gritty urban edge.

Waikahalulu Falls

Waikahalulu Falls, located within the serene and easily accessible Liliuokalani Gardens, is an urban oasis offering a tranquil escape in the heart of Honolulu. While not a towering, dramatic cascade, Waikahalulu Falls is a charming and picturesque series of small drops and pools that flow into Nu’uanu Stream. Its beauty lies in its peaceful setting, surrounded by lush, manicured gardens and historic stone bridges, providing a perfect spot for a leisurely stroll, a picnic, or quiet contemplation.

The falls are exceptionally easy to reach, making them ideal for all ages and abilities, including families with strollers or individuals with mobility challenges. This is a perfect attraction for those seeking a peaceful, low-impact encounter with nature, a pleasant photo opportunity, or a relaxing break from the city’s hustle and bustle. The cultural significance of the gardens, dedicated to Queen Liliuokalani, adds another layer of appreciation to your visit.

Hamama Falls

Hamama Falls offers a relatively easy and beautiful hike into a lush valley, culminating in a picturesque waterfall that feels like a hidden sanctuary. Located in the Kaneohe area, this trail requires a permit from the Board of Water Supply (BWS) because it traverses a watershed area. This permit system helps protect the valuable natural resources and ensures a less crowded experience for those who plan ahead.

The hike itself is mostly on a paved service road that transitions to a dirt path, making it a relatively gentle incline suitable for a wide range of fitness levels. As you walk, you’ll be immersed in dense tropical foliage, with the sounds of the stream accompanying you. The reward is a stunning, multi-tiered waterfall that cascades into a clear pool, offering a serene spot for relaxation and photography. This hike is perfect for those seeking a peaceful, moderately easy outdoor adventure with a beautiful waterfall payoff, and who appreciate contributing to the preservation of natural resources by obtaining the necessary permit.
