The Lava Flow campground & boat ramp is located south of the unimproved launch area that’s next to the actual lava flow.
When you turn off the highway heading to the unimproved launch go straight through the open green gate just before the road takes a hard right. The gate (and campground area) is closed until Sept 1st to protect nesting eagles in that area. From there just follow the signs… cant miss it.
If you see a chipmonk on an old stump you went too far

. Just kidding.
