I made it to Clear Lake Campground and to Trillium Lake Campground.
Trillium I don't think will work and the hike in would be a little tough for some.
Clear Lake campground is FULL of perfect trees and is rather Large.
Was a bit windy down on the beach but up a little higher was really nice.
Its my top choice as of now, I would like to do an overnight trip up there soon so I can do the hike from the Skyline snow park and see how that is.
