Hike the most scenic mountain stream trail in Hawai'i. It's a short trek along the side of the stream with beautiful, lush views.
Kawaikoi stream trail starts 3/4 mile beyond the Forest Reserve entrance sign on the Mohihi-Camp 10 road across the stream at "Sugi Grove". It's a DLNR maintained trail, so there's signage mile markers for the trail.
At 1.75 miles total-roundtrip, it's a very easy walking trail, great for families, especially with small children. The first half follows the southern side of the stream. The upper portion makes a loop, first going inland, then returning on the north side of the stream to reconnect with the first half.
If you're not too distracted by the beautiful surroundings, you will find wild strawberry guava blackberries to snack on in the winter-spring time ;)
At the starting point, on both sides of the Sugi Grove area, there are picnic areas compost toilets, which is a nice luxury out in the wilderness. There's NO drinking water/faucets, however.
