In the summer, you’ll want to bring or rent a boat of some kind to explore the river; there are many local outfitters. In the fall I’ve heard about the elk herds here and it’s not far from a wildlife refuge. Pros: outhouses, water (seasonally), beautiful landscape (cliffs, river, meadows), lots of water recreation, interesting (but tragic) local history, stargazing, choice of shady or open campsites, along river. Cons: bugs and mud (both seasonal).
