There's a trail up to an observation tower on Gorda Peak. On a clear day there is a great view from there.

Also, I recall a shorter hike starting from the beach at Biras Creek to the top of the hill - nice view of the North Sound from there.

BEYC used to have a small network of trails - I seem to recall they had a map of them available.

I recall a nice "hike" (more of a walk) from Great Harbor to White Bay on Jost.
