The lava tube is at a constant 42°F or 6°C...so dress accordingly.
Bring at least 2 light source. If you are soloing, I suggest a headlamp as your primary... you might need your hands free. Please make sure your children know not to shine their light at oncoming hikers.
The floor is uneven and you will need to scramble over some larger rocks. Sturdy shoes are recommended.
The entrance is awe inspiring. Especially when look up and out the way you came in with lighting.
When you reach the bottom of the metal stairs it will almost be total darkness. You have 2 paths select from.... under the stairs takes you 1.5 miles one way (I did not take that route) the other route is .75 miles one way.
I an not going to dishonor the amazing trek but trying to describe what you will see. But it's pretty cool. I attached some pictures.
