Ke‘anae Peninsula is an isolated and wildly beautiful place where the surf pounds against jagged lava rocks that edge a gnarly coastline. Turn left on Hāna Highway, a half-mile past mile marker 29. This is a detour that won’t disappoint and, as luck would have it, boasts public restrooms.
Nearby KE‘ANAE ARBORETUM is located in a tropical forest setting on leveled terraces built hundreds of years ago by Hawaiians for taro cultivation. A short, relatively flat asphalt walkway travels through the arboretum, but no guided walks or facilities are available.
To find the arboretum, take Highway 360, a little more than half a mile past mile marker 16.
Parking is on the side of the road near the arboretum sign.
