Let’s explore Kaumana Caves in Hilo, Hawaii

Created during the 1881 lava flows into the areas around Hilo, The Kaumana caves are a fascinating place to explore as part of the Kaumana Caves State Park and they are free to visit. You can visit the entrance to the cave areas and a short distance before it actually becomes private property and you cannot go further. (There are no boundary marks to designate private property)

Let’s explore Kaumana Caves in Hilo, Hawaii

History of the Kaumana Caves

The Kaumana caves were formed by the 1881 lava flows from the flanks of the Moana Loa volcano active during that timeframe that stopped abruptly above Hilo which was a very small town during that timeframe. The lava tube formed as faster lava stays in a channel area while the cooled areas on top create a crust surrounding the tube and acts as an insulator while the hot and fresh lava continues below the surface forcing lava downhill. The molten lava finally erupts at the end and with no fresh lava from the source creates an empty tube or cave as we see today.

The Kaumana caves extend out a distance of over 20 miles on mostly private property. There is actually no clarification on what parts of the tube are public property and which parts are private so enter the caves at your own risk. The entrance to the lava tube is through a flight of stairs to a collapsed portion of the Kaumana Caves and splits into two separate areas to explore and the largest one is on the right hand side.

Where are the Kaumana Caves Located?

Locate Kaumana Caves State Park on Kaumana drive between the 4- and 5-mile markers (right after 4 mm) and there should be a sign up ahead for the Kaumana Caves and parking. The parking area is on the south side of the road, but the park is on the north side, just across from the road. Enter down the flight of stairs to either side of the lava tubes which actually is a collapsed portion of the lava tube itself.

Details to visiting Kaumana Caves

After descending the ladders to the entrances, there are two openings to explore around the park. You can explore for a short distance but afterwards the tunnels go through private property and should not be explored the entire length of the lava tubes. The crashed opening is lush with gorgeous tree ferns, indigenous plants and other tropical plants that thrive in this wet and beautiful areas surrounding the openings to the cave.

The larger tube is on the right side and is light for a short distance until it gets extremely dark, there are no trails and you have to climb over jagged rocks in the cave.

There are picnic grounds and toilets around the grounds above the cave areas.

Bring plenty of bug spray since the area is very lush and wet

Also have a few light sources if you plan on going into the cave

Wear Sturdy shoes since the area is mostly slippery rocks and mud.

It is probably acceptable to just explore a short distance from the entrance where the cave gets extremely dark and you can return back safely to the opening

Enter at your own risks, there are no trails or walkways beyond the stairs down to the caves and there are no boundary signs as to what is private property space within the caves.
