Waterfalls in Oahu: Introduction

Waterfalls in Oahu are simply amazing!

Oahu, the third-biggest of the eight main Hawaiian islands, is an incredibly beautiful tropical island with mountains, valleys, forests, beaches, and of course, the most beautiful waterfalls!

Waterfalls are one of my favorite things to see on Oahu: a fitting reward after a hike through the jungle. They are also great places to cool off, swim, or even jump into from cliffs.

There are hundreds of waterfalls on Oahu, but only a few are easy to access or open to the public. Some of them require a long hike, a permit, or a guide to reach them.

Others are on private property or sacred land that you need to respect. That’s why I have selected the 10 best waterfalls on Oahu that you can see or hike to without too much hassle.

While some of these are waterfalls from majestic heights, others are much smaller but with beautiful natural pools that you can swim in or stunning hikes through lush, tropical jungles and dense bamboo forests!

Geological Forces Shaping Oahu’s Waterfalls

Oahu was formed by two volcanoes (Waiʻanae and Koʻolau) that erupted millions of years ago. They are not active anymore, but they created the steep mountains, reaching up to 4,000 feet, and the beautiful valleys that you see today.

Waterfalls in Oahu are mostly found in the wet forests on the windward side of the island.

The windward zone is the side of the island that faces the northeast trade winds. This side of the island receives plenty of rain and has many valleys and streams that feed into waterfalls.

The windward waterfalls are usually more lush and green, surrounded by tropical plants and flowers. They are also more likely to have clear and fresh water, since they are fed by rainwater.

The leeward zone is the side of the island of Oahu that is sheltered from the trade winds, and receives less rainfall.

The leeward waterfalls are usually more dry and brown, surrounded by rocks and cacti, and often completely dry up! They are also more likely to have murky and brackish water, since they are fed by groundwater.

The peak flow of the waterfalls on Oahu depends on the rainfall and the season. Generally, the waterfalls are more full and powerful during the winter months (November to March), when there is more rain and storms.

If you want to see the waterfalls at their most spectacular, you should visit them during or after a rain, when they are more swollen and roaring. Be careful of flash floods, landslides, and slippery trails.

If you want to swim or jump in the waterfalls, you should visit them during a dry spell, when they are more calm and clear. But you should also be aware of bacteria, algae, and leeches in the water.

Note that some of the below waterfalls can be reduced to a trickle or even completely dry, depending on the recent weather.

Never mind, the hike through Oahu’s rainforests is always fabulous!

Manoa Falls

The most popular and easy waterfall to visit in Oahu is Manoa Falls. This waterfall is located in Manoa Valley, a beautiful, green valley, about 5 miles from downtown Honolulu.

Manoa Falls is one of the tallest waterfalls in Hawaii at 150 feet high and falls into a small pool of water, and is especially impressive to see after rain.

The waterfall was featured in movies and TV shows such as Jurassic Park and Lost. Some of the scenes filmed here include the dinosaur chase, the plane crash, and the hatch.

Hike on Manoa Falls Trail

To get to Manoa Falls, you need to drive or take a bus to the end of Manoa Road, where you will find a parking lot and a trailhead. The parking lot charges $5 per car, but you can also park for free on the street if you find a spot.

The trailhead has a sign with information and maps of the area.

The hike to Manoa Falls is about 0.8 miles one way, or 1.6 miles round trip. It takes about 30 minutes to an hour to complete, depending on your pace and how long you stay at the waterfall.

The hike is easy and family-friendly, but it can be muddy and slippery, so wear good shoes and be careful.

The hike starts on a gravel road that leads you through a eucalyptus forest. You will smell the fresh and minty scent of the trees as you walk.

Then, the trail becomes a dirt path that goes uphill through a lush rainforest with ferns, bamboo trees, ginger plants, and guava trees.

You will also hear and see many birds, such as cardinals, doves, and honeycreepers.

The highlight of the hike is the waterfall itself. When you reach the end of the trail, you will see Manoa Falls in front of you, cascading down a rocky cliff into a clear pool.

The waterfall is very beautiful and photogenic, especially when the sun shines through the mist and creates rainbows. You can get close to the waterfall and feel its spray on your face, but you cannot swim in the pool because it is dangerous and prohibited.

Manoa Falls can also be accessed via the Aihualama Trail, a more difficult but less crowded hike!

While visiting Manoa Falls, you can also see Lyon Arboretum, a botanical garden, and Paradise Park, ruins of a former amusement park.

Treetops Restaurant located near the trailhead, with a view of the valley, offers a buffet lunch.

I visited Manoa Falls with my family when we went to Oahu for our last vacation. We had a great time hiking through the forest and admiring the waterfall.

I thought the hike on Manoa Falls Trail was one of the best waterfall hikes I’ve been on, an easy hike, but very beautiful!

It was very cool to see the locations where scenes from Jurassic Park and Lost were filmed.

Tips for Visitors to the Best Waterfalls of Oahu

Oahu is home to many beautiful waterfalls that you can hike to and enjoy. However, there are also some risks and challenges that you should be aware of before you go.

Bacteria in the pools

Many of the waterfalls in Oahu have pools that you can swim in, but be careful of leptospirosis, a bacterial infection that can be contracted from contaminated water. If you have any open wounds or cuts, avoid swimming or jumping in the water.

Do not drink the water or let it get into your eyes, nose, or mouth. If you develop any symptoms such as fever, headache, muscle pain, or rash, seek medical attention immediately.

Rock falls and the Sacred Falls tragedy

Some of the waterfalls in Oahu are located in areas that are prone to rock falls, especially after heavy rain. This can be very dangerous and even fatal, as it was in 1999 when eight people were killed and dozens injured by a massive rock slide at Sacred Falls.

Heed the signs and warnings and stay on the designated trails.

Trail conditions, especially after rain

Many of the trails to Oahu waterfalls are steep, rocky, muddy, and slippery, especially after rain. You’ll need good hiking shoes, water, and snacks.

Be prepared to cross streams and climb over rocks and roots. Use caution and common sense when hiking and do not go beyond your abilities.

Avoid hiking after heavy rain, as the trails can get flooded and dangerous. Check the weather forecast and trail conditions before you go.

Permits

Some of the above waterfalls and trails are on private property, and require a permit (usually free). Make sure you apply for the permit well in advance, and print copies of the permit to carry with you and display on your vehicle.

Crowds

The best waterfalls in Oahu are also the most popular, and crowded on holidays and peak times. The best time to visit these waterfalls are early morning and weekdays.

Renting a Car in Oahu

If you want to explore more of the island of Oahu on your vacation, you should get a rental car.

Oahu’s popular attractions are spread over the island: the windward coast, the North Shore, and Ko Olina are great places to explore beyond Waikiki (or the greater Honolulu area).

While Oahu does have public transport options that are better than the other islands, a car offers a lot more flexibility and time savings.

We always use Discover Cars to book Oahu car rentals. They search across a variety of rental car companies, both budget and brand, to offer you the best deals, AND they offer free cancellations. Plus, there are no hidden fees.

Honolulu Airport-Hotel Shuttle

If you are not planning to get a rental car at Honolulu Airport, consider booking shuttle transport in advance!

This shared shuttle can be canceled up to 24 hours from the date of service. It serves hotels in Waikiki and Honolulu and then back again to the airport the day you leave. It’s convenient and inexpensive, and saves time and hassle!

Where to Stay in Oahu

Honolulu (Waikiki in particular) offers a large number of hotels and resorts, along with shopping and dining options. Most visitors to Oahu choose to base in Honolulu at least for a part of their stay.

While many of the large chains have a presence if you are looking to use your memberships, Honolulu also has several unique boutiques to consider.

Our faves include Halekulani for a splurge stay, the Lotus Honolulu for views of Diamond Head, and The Laylow for its awesome location.

Want more room to spread out or looking to stay elsewhere on Oahu? You will find VRBO listings all over the island!

On previous trips to Oahu, we have stayed in VRBO rentals in Waikiki as well as on the North Shore and the east coast and we’ve found the choice and quality great.
