I don't know anything about Wolf Creek, but if they've got trails and such for folks that wanna hike, that sounds awesome. Also don't know anything about how off-season camping works there, nor their policies on hammock camping.

What's been your experience with that stuff there?

As I've mentioned, the only 'local' experience I've had so far is Woodridge, but I can reach out to other places and find out costs/policies for off-season and hammocks.
