The Jackson demonstration forest was a great place to forage some mushrooms. You do need a permit, which was affordable and last a year. Otherwise it's a great place to hike and enjoy an afternoon. It's pretty remote and the roads are gravel with a lot of logging roads. There was a porta potty at one of the parking sites, but otherwise there is not much infrastructure (bathrooms, water, etc), so be sure to bring plenty of water and food.
