From the entrance, the lava tunnel leads in two directions. The tunnel system is 2,197 meters long in total. Sturdy footwear and sufficient lighting are recommended.

The water on the upstream side runs through an old lava tube. I'm told (but haven't seen myself) that when the water isn't too rough, you can carefully hike upstream through the tube to see two waterfalls. There's good parking for several cars just past the bridge in the direction away from Hilo (towards Pepeekeo).

The Kawainui Stream Bridge has become a little attraction around this rainforest because some people like to jump from the bridge into the water. Warning: Jumping off the bridge can be dangerous, as the river level can change and it can become too shallow. Jumping is not recommended.

Onomea Bay has an amazing view of rocky shores, crashing waves, and a nice viewing platform. The waters are a bit too rough to swim, especially with all the lava rocks. The jungle surrounding the shores and trail are amazing with flowers and thick vegetation.

Rainbow (Waiānuenue) Falls is a large waterfall, measuring 80 ft (24 m) tall and almost 100 ft (30 m) in diameter. It is free to enter and see the falls because this area is part of the Hawai'i State Parks. There is no fee to see the falls. Rainbow Falls gets its name from the rainbows that show around the falls, created by the mist from the falls and the sunshine at 10:00 a.m.

Kaumana Cave is a lava tube that is free to enter. It was made by an 1881 lava flow from Mauna Loa volcano. The lava tube has been measured at just over two miles long, which ranks it as the 57th longest lava tube in the world. There is a warning sign at the entrance that indicates: "no lights, no walkways, sharp and loose rocks". Visitors should heed the warning and bring good shoes and a light.
