Oahu’s stunning landscape features some amazing waterfalls that I’ve been lucky enough to explore over the years. From easily accessible cascades perfect for families to hidden gems requiring adventurous hikes, the island offers something for every waterfall enthusiast.
The best waterfalls on Oahu combine beautiful scenery, swimming opportunities, and hiking adventures that showcase Hawaii’s natural beauty. I’ve found that visiting these waterfalls provides a refreshing escape from the island’s popular beaches and gives you a chance to connect with Oahu’s lush interior landscapes. Many of these waterfalls are located within tropical forests, where you can experience Hawaii’s diverse plant and animal life up close.
Manoa Falls
Manoa Falls is one of Oahu’s most popular waterfall hikes, and it’s easy to see why. I was immediately struck by the lush rainforest surroundings as I made my way along the trail. The path winds through a stunning botanical garden and bamboo forest before revealing the majestic 150-foot waterfall.
The hike to Manoa Falls is relatively short, about 1.6 miles round trip. I found it accessible for most skill levels, though parts can be muddy and slippery after rain. I’d recommend wearing proper footwear and bringing a small bottle of water for the journey.
When I reached the waterfall, I was mesmerized by how the water cascades down the rocky cliff into a small pool below. The mist from the falls created a refreshing atmosphere, especially welcome after the humid hike through the valley. I noticed many visitors taking photos, as the scenery is truly Instagram-worthy.
I visited early in the morning to avoid crowds and had a more peaceful experience. While swimming isn’t permitted at the falls for safety reasons, just standing near this natural wonder and feeling its cool spray made for a memorable Oahu adventure.

Mānoa Falls Trail
I recently hiked the beautiful Mānoa Falls Trail in Honolulu, and it was truly a refreshing experience. This 1.7-mile round trip journey takes you through a lush rainforest setting that feels worlds away from the busy beaches of Waikīkī. The trail leads to a stunning 150-foot waterfall that’s well worth the effort.
The path has been renovated recently, making it much less muddy than it used to be. While it’s mostly uphill to reach the falls, the hike isn’t too challenging and takes about 30-45 minutes each way. I’d definitely consider this one of Oahu’s most accessible waterfall hikes.
Be aware that although the waterfall is beautiful to look at, swimming at the base is prohibited. I noticed clear warning signs and there are reports of people being fined for ignoring them. The area can also get quite busy, so I recommend visiting early in the morning to enjoy a more peaceful experience.
The trail is surrounded by tropical vegetation, creating a magical jungle atmosphere. I loved how the sunlight filtered through the canopy, creating beautiful light patterns on the path. The sound of the waterfall gets louder as you approach, building anticipation for the final reveal.

Maunawili Falls
Maunawili Falls is one of my favorite waterfall hikes on Oahu. The trail takes you through a lush rainforest with beautiful mountain views along the way. I was amazed by how green everything was during my recent visit.
The hike itself is moderately challenging and can get muddy, especially after rain. I recommend wearing proper hiking shoes and bringing bug spray. The trail is about 2.5 miles round trip and includes some stream crossings that add to the adventure.
When I finally reached the falls, I was rewarded with a picturesque waterfall cascading into a swimming hole. Many visitors enjoy jumping from the rocks into the pool below, though I preferred to just wade in the refreshing water. The swimming area is perfect for cooling off after the humid hike.
The best time to visit is on weekdays when there are fewer people. I arrived early in the morning and had some peaceful moments at the falls before it got crowded. Remember to respect the natural environment and take any trash with you when leaving.

Lulumahu Falls
I recently hiked to Lulumahu Falls and it was absolutely breathtaking! This hidden gem requires a bit of adventure to reach, as you’ll need to cross a creek and navigate through a gorgeous bamboo forest to find it.
The trail is unofficial and unmarked, which adds to its charm but also means you need to come prepared. I recommend wearing shoes that can get wet and bringing plenty of water. The hike isn’t too difficult, but there are some slippery sections to watch out for.
What makes this waterfall special is how secluded it feels despite being relatively close to Honolulu. When I arrived at the falls, I was rewarded with a stunning cascade of water plunging into a refreshing pool. The surrounding lush greenery creates a magical atmosphere that’s perfect for photos.
One important thing to know is that you’ll need a day use permit from Hawaii’s Division of Forestry and Wildlife before visiting. I printed mine ahead of time and kept it with me throughout the hike as required.

Waimea Falls
Waimea Falls is truly one of Oahu’s natural treasures. I visited this 45-foot waterfall on the North Shore and was amazed by its beauty. What makes this waterfall special is that it’s accessible via a paved path through stunning botanical gardens.
The journey to the falls is as memorable as the destination itself. I enjoyed strolling through the lush gardens, taking in the diverse plant life and peaceful atmosphere. For those who prefer not to walk, there’s a convenient shuttle service available.
When I reached the waterfall, I couldn’t resist taking a refreshing swim in the pool below. The water was cool and rejuvenating after the walk. I recommend bringing a towel and swimwear if you plan to take a dip like I did.
The entire Waimea Valley is rich with Hawaiian cultural significance. During my visit, I noticed various cultural demonstrations and exhibits along the path that helped me appreciate the historical importance of this beautiful place.

Likeke Falls
I recently visited Likeke Falls and found it to be the perfect family-friendly waterfall hike on Oahu. The trail is incredibly short at just 0.9 miles round trip, making it ideal for those who want to see a beautiful waterfall without a lengthy trek.
What makes Likeke Falls special is that it flows year-round since it’s spring-fed rather than rain-fed. This means you’re guaranteed to see the multi-tiered cascade no matter when you visit. The minimal elevation gain along the trail is another bonus, especially compared to the more strenuous Manoa Falls hike.
Be prepared for mud! This was definitely one of the muddiest trails I’ve hiked on the island, regardless of recent rainfall. The path starts at a service road leading to a water tank, then winds through dense jungle before you begin hearing the soothing sounds of falling water. The cool pool at the base is perfect for cooling off on a hot day.

Waimea Falls
I recently visited Waimea Falls, and it was truly a magical experience. The waterfall is located in the beautiful Waimea Valley on Oahu’s North Shore. Walking through the lush botanical gardens to reach the falls was just as enjoyable as seeing the waterfall itself.
The path to the falls is about 3/4 mile long and offers amazing views of native Hawaiian plants and flowers. Everything is clearly labeled, so I learned a lot about the island’s flora. There were even guides at the Hawaiian village huts who shared fascinating cultural information.
When I finally reached the waterfall, I was amazed by its beauty. The falls drop into a swimming pool surrounded by gorgeous foliage. I took a refreshing swim in the cool water – they provide life jackets for safety. The area around the falls creates a peaceful atmosphere that made me feel connected to nature.
I’d recommend wearing comfortable shoes and bringing a swimsuit if you plan to take a dip. The botanical garden setting makes this more than just a waterfall visit – it’s a complete cultural and natural experience.

Mānoa Falls
I recently hiked to Mānoa Falls and was completely mesmerized by its beauty. This stunning waterfall is tucked away in a lush rainforest valley just minutes from downtown Honolulu. The 150-foot cascade creates a peaceful atmosphere as water tumbles down into a small pool below.
The trail to reach the falls is about 1.6 miles round trip. I found it moderately challenging with some muddy and rocky sections, especially after rainfall. Wearing proper footwear is definitely a must – I learned this the hard way after slipping on some muddy patches!
The dense jungle surrounding the path feels magical. Giant bamboo groves, colorful tropical plants, and the sounds of birds create an immersive experience. I spotted several interesting native plants and even a few wild chickens along the way.
The waterfall itself feels like a reward after the hike. While swimming isn’t allowed at the base of the falls, I spent time enjoying the cool mist and taking photos. The best time to visit is weekday mornings when there are fewer people around.

Waipuhia Falls
Waipuhia Falls is one of the most magical waterfalls I’ve seen on Oahu. What makes it truly special is its nickname “Upside Down Falls.” When the wind blows strongly, the water appears to flow upward instead of down!
I visited during a slightly windy day and was lucky to witness this incredible phenomenon. The water seemed to defy gravity, creating a misty spectacle that left me speechless. It’s definitely worth timing your visit on a windy day if possible.
The hike to reach the falls is moderately challenging but absolutely worthwhile. I recommend wearing proper footwear as the trail can get muddy and slippery. The lush surroundings along the way showcase Hawaii’s beautiful native plants and offer plenty of photo opportunities.
When I reached the viewing area, I spent nearly an hour just watching the water dance with the wind. The surrounding valley creates a natural amphitheater that amplifies the peaceful sounds of rushing water and rustling leaves.

Sacred Falls
Sacred Falls is one of Oahu’s most beautiful waterfalls, tumbling dramatically down a sheer cliff face. When I visited, I was struck by the lush greenery surrounding the falls and the refreshing mist in the air.
The waterfall is located on the northeastern side of Oahu in the Koolauloa area. It’s important to note that Sacred Falls State Park has been officially closed to the public since 1999 due to deadly rockslides. Access is prohibited and trespassing can result in hefty fines.
I could see why this place was once a popular hiking destination. The tall cascade drops into a pristine pool surrounded by steep valley walls. The natural beauty here is truly breathtaking, though I respect that it must be appreciated from afar for safety reasons.
While I couldn’t get too close, even viewing Sacred Falls from a distance gave me an appreciation for why it earned its name. There’s something truly spiritual about the way the water cuts through the ancient volcanic rock.

Understanding Oahu’s Waterfalls
Oahu’s waterfalls are shaped by unique geological conditions and seasonal rainfall patterns. These natural wonders range from accessible tourist spots to hidden treasures tucked deep in rainforests.
The Geography of Oahu
Oahu’s waterfalls exist thanks to the island’s volcanic origins and abundant rainfall. The Ko’olau and Waianae mountain ranges catch moisture-laden trade winds, creating perfect conditions for waterfall formation.
The eastern and northern parts of Oahu receive the most rainfall, which is why you’ll find popular cascades like Manoa Falls and Waimea Waterfall in these regions.
The island’s steep valley walls carve perfect channels for these flowing waters. Many waterfalls are nestled in lush valleys that were formed millions of years ago by erosion.
Waterfall Types and Features
Oahu’s waterfalls come in several types, from single drops to multi-tiered cascades. The water volume varies dramatically based on recent rainfall, with some falls like those in Mānoa Valley showing significant changes throughout the year.
Many Oahu waterfalls feature swimming holes at their base. Popular swimming spots include Waimea Falls and Maunawili Falls, where you can cool off after your hike.
Some falls are perfect for cliff jumping, though I always recommend checking water depths and current conditions first. Safety is crucial, as tragic accidents have occurred – Sacred Falls State Park has been closed for 25 years due to dangerous terrain.
The surrounding flora and fauna make each waterfall unique. You’ll spot native Hawaiian plants, colorful birds, and sometimes small freshwater fish in the pools below the falls.
Planning Your Waterfall Adventure
Visiting waterfalls on Oahu requires some preparation to make the most of your experience. I’ve learned that timing and proper gear can make a huge difference in your waterfall adventure.
Best Time to Visit
The best time to visit Oahu’s waterfalls is during the rainy season (November to March) when water flow is strongest. After heavy rain, Manoa Falls and other popular falls are at their most impressive.
However, be cautious as trails become muddy and slippery. Flash flooding can also be dangerous. I recommend checking the weather forecast before heading out.
Early morning visits (before 9 AM) help you avoid crowds, especially at popular spots like Waimea Falls. Weekdays are much less crowded than weekends.
During summer months, some smaller falls like Maunawili might have reduced flow, but the hiking conditions are generally drier and more comfortable.
What to Pack for Your Trip
When you hike to Oahu waterfalls, you need proper gear. Here’s what I always bring:
Footwear:
- Hiking shoes with good grip (trails get muddy and slippery)
- Water shoes if you plan to swim
Clothing:
- Quick-dry clothes
- Swimwear for falls that allow swimming
- Light rain jacket or poncho
Other Essentials:
- Plenty of water (at least 1 liter per person)
- Bug spray (mosquitoes love the humid forest areas)
- Sunscreen (even on cloudy days)
- Small towel
- Waterproof bag for electronics
- First aid kit with bandages and antiseptic
I always bring a snack to enjoy at the waterfall viewpoint. Respect nature by taking all trash with you when you leave. For longer hikes like Lulumahu Falls, I pack extra water and energy bars.
