Best mountain swim on Oʻahu!

If lush tropical valleys and pristine mountain pools is your thing – you cannot miss this tour! Hikers will board a military all-terrain vehicle in Hale’iwa town and off-road 7 miles mauka (mountain ward) to the trailhead.

High in the Ko’olau mountains is a valley of unparalleled beauty with an abundance of exquisite freshwater pools and the best mountain swimming on the island! Possibly the most delightful hike on O’ahu, this trail includes 10 stream crossings and an amazing array of tropical flowers and fruits. See wild tangerines, liliko’i (passion fruit), ‘ohi’a ‘ai (mountain apple), mango, hau (sea hibiscus), and much more!

Enjoy the islands through Hawaiian eyes as your expert guide shares the history, language, and mo’olelo (stories) of Hawai’i and its fascinating environment. The “Nui” however, is all about the wai (water), so get your swimsuit on and strap up the hiking boots North Shore EcoTours is taking you on an adventure – Hawaiian style!

This was the perfect tour for me and my wife. We don’t really do a lot of hiking but we loved getting closer to nature along the trails here. This definitely gave us some amazing photos for our trip.

I can tell you this is one of the best swims that we had during our time in Hawaii. The vehicles that they have on this tour are absolutely incredible and exploring the mountain/being taken to some of the private swimming areas made for some amazing photos at the end of the tour.

Excellent for an all-day activity, guides are full of information, we learned many new words and their meaning, the pool was the crown jewel of the tour.

Very cool tour. Educational and fun. It has everything you could ask for in a mountain hike, from wild animals to colorful plants and the dip in the pool was very refreshing although it was raining it was filled with excitement and fun.

My friends and I enjoyed this activity yesterday and even though I am sore the tour was a wonderful thing to do as a group, we all loved to swim in the water pool. The views from the top were breathtaking. even the first part on the truck, it was very fun and bumpy, we all loved this tour. we recommend this to anyone that loves outdoor activities.
