Lots to do in this park with local history and geology being the focuses. Not far off 90 if you’re road tripping. The campground is simple and open. Pros: different sleeping options (tent, RV, cabin, yurt, tipi), cave tours, river access, short hiking trails, lots of history (native, mining, settlers, etc), ranger talks, ice/wood camp store, helpful rangers, stargazing, nice modern bathrooms. Cons: very open campground with no privacy nor shade, no tent-only area, lots of RVs. We’d definitely visit again.
