I stayed here in spring of 2007, and was struck by how similar it was to Northern California, with the tall eucalyptus trees, and cute little cabins.
The camping bathroom didn't have showers, but the communal bathroom for the cabins did, and a sympathetic cabin renter let me into that bathroom. (I'm a bike tourist, so I really need the shower.)
I spent two nights here, because the second day I went for the dusk hike among the lava fields. Note to bikers, make friends with someone at the bottom who can drive you up, because it is a big climb not to be biked up in the dark.
There was a pavilion with a stone fireplace that was very attractive for groups.
