Located about five miles north of downtown Hilo on Highway 200 (Saddle Road), Kaumana Caves is actually a large lava tube formed during the 1881 erruption of Mauna Loa. You can't miss signs for the cave on your right as you drive north.
You walk down a steep staircase and into a large opening. You will see and smell tropical foliage and wildflowers. Bring a flashlight if you want to hike further into the lava tube.
