Castle Rock

Castle Rock Fishing Access Site, managed by Montana Fish, Wildlife & Parks Region 5, puts campers directly on the Stillwater River in Nye, Montana. Sites are large and spread out enough that even a full Labor Day weekend crowd doesn't feel compressed. No hookups are available, and cell service is absent for miles in any direction, so plan accordingly.

Fishing is the primary draw here. An elevated cement platform beside the river gives anglers a raised vantage point, and a deep pool across the water draws swimmers who use the rock ledge as a diving spot. The rocky riverbank also makes this a reasonable stop for rock hounding. Snakes are present among the river rocks, worth keeping in mind for anyone with dogs or small children, though pets are permitted on-site.

Amenities are straightforward: a vault toilet, picnic tables, fire rings, and firewood available on-site. Bring a flashlight since there's no lighting at the facilities after dark. Pay at the entrance so the site host knows you've checked in. Kathi F. notes "a really cool, elevated cement lookout area next to the river." The campground is consistently described as clean and well maintained. Buffalo Jump Camp sits a few miles to the southwest for those wanting a nearby alternative, and there are additional campgrounds near Castle Rock Fishing Access Site worth considering for longer stays in the region. This site works best for anglers and river-focused campers who don't need electrical hookups or reliable connectivity.
