Visit Kipahulu Visitor Center: No food, gas, or water here, however you’ll find interesting natural history and cultural exhibits, as well as informative naturalists available to answer questions. Permits can be picked up here.
Go on a Self-Guided Hike: on the lush, easy loop past Kuloa Point, or the more difficult Papwai Trail to see and waterfalls and as many as 24 pools.
Swim in the freshwater pools at Oheo Gulch: These are prone to flash-flooding so know weather conditions before you jump in. (getting washed out to sea will ruin your vacation)

Photograph the rain-forest: This lush, wet environment will provide endless subjects for your camera.

Ride a horse: in the Kipahulu area. This is an excellent choice for a rain forest experience.
Look for Pictographs: made by locals who lived here long ago.
Car-Accessible Camp: At Kipahulu campground, about 1/8 mile south of the Kipahulu Visitor Center, and a short walk from Oheo Gulch. Experience the night sounds of nearby ocean waves as you camp above sea-side cliffs, but be ready for rain, lots of sun, and pesky mosquitoes. Permits to camp are not required, but no reservations are accepted.

You might See: Whales, turtles, dolphins and seabirds. Views from the cliffs often yield wonderful surprises.
