Hiking boating good ramp


mix of day and overnight use

Black Sandy campground.

This is primarily a RV campground and boating access campground. Only A few tent only sights. With the exception of the first few sites, the rest are RV sites packed in tight. Short trail leads to a good overlook of the lake. Nice picnic area just past campground. Campground has flushing toilets during the main season, outhouses the rest of the year. Good hiking trail along the Missouri river is just down the road at the dam.

Outside Helena

Nice big state park campground, but it fills up quickly. Views are good but they aren’t the Montana stereotypical snow-capped peaks. The camp sites where we stayed were pretty close together but right on the water. Good place to stay for a day passing through or for longer if you just want low-key time on the water.

Jumping off point

This campground is pretty small but is located right on the edge of the lake making for some nice views and a relaxing environment. There are bathrooms, small docks, a swimming area in the lake, fire pits, and water. The best thing about this campground is the proximity to Hauser Dam. There are some wonderful hikes around the dam as well as great fishing. If you are there in August you can see the largest concentration of Bald Eagles west of the Mississippi.

Nice Little Place

Spent the weekend here mainly because it was cheap and I was really happy with what I got. The campsites were a little small and crowded if you have a bigger group and there wasnt any portable water. Despite this, it was really clean and nice.

Black Sandy

Very few camp spots, a few pull off picnic areas, farther down by the Hauser damn is really good trout fishing!! Browns are release, Rainbow and brook trout below the damn. Good spot to take the kids fishing, no pests to bug them :) rope swing in to water, water is wading level.
