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.

This marks the start of Mauna Kea! From here you can enjoy the views of the absolutely gargantuan mountain overhead. By this point whether you rode from Hilo or the west coast, you've already done enough climbing to put most cyclists to shame. You can give yourself a pat on the back and enjoy the long descent back into town, or drop a gear and head up the mountain!

Kawaiku'i Beach Park is a tucked-away park with rocky beaches, grass to play games, and benches for a picnic. The water is a bit shallow and murky, so swimming is not as good as other beaches, but that means less people will be here.

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.
