This island is the farthest away and the campgrounds are very small (only 9 sites) but the voyage is worth it. Apparently its high point is in the winter when people come from all over to see the 20,000 or so sea lions and seals, but when we were there they seemed to be replaced by hundreds and hundreds of birds of all sorts. Birdwatchers would probably love it there. There are wildflowers everywhere painting the grasses and jaggy coastlines.
There are a couple of geologic and historic neat things to do here. There''s a fossil of a pygmy mammoth and sociological remnants of human civillization from 10,000 years ago... but the most facinating was the "caliche forest". This is a ghost forest... once long ago there was a forest here, and you can see caliche sand castings of roots and trunks and leaves, but the plants are long gone. It''s very eerie.
Reservations far in advance are required, permit required, camping free, reservation fee $2.50 by calling number. It''s at least a mile hike uphill to camp site and you must carry everything on your back, so make sure you''re fit before thinking of coming. No wood can be brought in, but instead charcoal or firelogs are recommended. Bring sturdy tentstakes lines and windbreaks as the wind here is very fiesty.
