Be prepared for the hike, a swim, and an amazing campsite

You have to hike down a hill to get there, but it is super pretty. It’s in a valley, so it will get cool at night and is warm during the day, but it’s super quiet, and an amazing spot.

The hike down can be a bit steep and if it is raining it gets SUPER wet and slick. It is worth it! A beautiful pristine beach, waterfalls all around, and towering green mountains covered in dense jungle. Absolutely amazing! Be sure to pack in enough water and food! hike back to cars isnt too bad either if more supplies are needed.

Phenomenal!!!

Waimanu Valley is a state campground for backpacking. It starts out at Waipio Valley lookout and continues 9 miles up to the next valley over. It's a moderately strenuous hike with a pack on your back! Be prepared with water filter, rain gear, mosquito repellant and everything else you need for backpacking. Check the weather in advance because there are two stream crossings that can get rather dangerous if it rises. Otherwise this is the most fantastic paradisiacal campsite on a beach you'll find in Hawaii! Less people than the popular Kalalau on Kauai. Research this one a ton and get permits far in advance!
