Kaltxi ma 'eylan, Sure no problem. Below are a few useful links. I believe the Callam buses go along highway 101 past the entrance to Sol Duc, but I think the camp is some 5 miles down that road. If you get off at Port Angeles you could possibly get a taxi from there, but I think it is about 30 miles from there to the camp. Maybe they should have picked somewhere a bit more accessible for everyone? Anyway, here are the links. Hope they are of use:
Olympicbuslines.com - article
Clallam Transit - Home
Jefferson Transit: Bus to Seattle/Sequim/Kitsap County
WSDOT - Choices - Travel by Bus
As I said in the thread, I'm sure someone will be able to pick you up along the way. Aketuan is leading the camping trip and will be able to help you more than I as I'm flying in too.
Eywa ngahu,
