I drove by near
this cave many times but never walk in. This is nice lava tube not as impressive
as the lava tubes that are in Lava Beds National Monument, but it is fun to
have a short stop on your way and visit this place.
How the cave was formed:
20,000 years ago large lava flow covered 16 miles of Hat Creek Valley. While
the top crust cooled and hardened, rivers of hot lava continued to flow in the
tubes. Eventually, the lava drained away, leaving empty tube-like caves. The
entrance to the cave was formed by a collapse of the cave’s roof.
trail is approximately 1/2 mile long.
parking lot there is a very short trail leading to the cave entrance.
down into the open of the cave.
Once you enter
the cave and start to progress inward it get completely dark, so don't forget
to bring a flashlight.
walk inside the cave and few bends you will see the light from the exit where another
set of stirs leading out.
The cave itself
is big, you do not need to crawl or bend and the floor, unlike other lava
caves, is relatively flat.
This is a very
short walk from one side of the cave to the other side.
You can walk
back to the parking lot or as we did walk back into the cave and went back on
the same way we walked in.
This is short
fun walk, a rest on your trip where kids and adult will enjoy at.
