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.

The boiling posts are sink holes with bubbling waters. For safety, it's best to stay far away from the edge of the river near Boiling Pots. Visitors are warned about the dangers of slipping and falling. The bubbling is caused by the water in the lava tubes, which are not boiling hot but give the illusion of boiling. This is a very unique thing to see, and it is highly recommended for visitors to walk down and check them out.
