Well maintained, reasonably priced campground. A couple of miles of dirt roads coming in. Make sure to fill your water tank at the dump station before you get to the campground. Good 50 amp electric and bathrooms are clean. Lovely sites right on the river. BUT they are so close together we couldn’t put out our awnings. Very popular spot for local families to bring their boats.

This is more of a RV camping and parking area than a great picnic spot although there are tables and fire rings. There are restrooms in a fairly new building. There is also a boat ramp and docks. On this day in late September there were still several RVs although not many people out and about. It's not a terribly scenic or wild area although the lake is nice. It's not a good swimming area. Dogs have to be leashed. Hiking trails weren't obvious. The picnic areas might be hard for wheelchair access because they are hills.

A very nice little state park. Well maintained and with necessary facilities for tents, RV, boat docks/ramp, and swimming. RV spaces are 2 per space. There is AC power, water and a dump station for the traditional fee of $5.00. Additional parking is available. Volunteer staff were courteous and friendly. We never did see the park store open, but that may be a ‘seasonal’ thing. Driving into the park, be careful of the downhill, gravel roads. You could very easily loose control coming down into the parks. Also, there is a narrow road past the park that will take you to Hauser Dam. The park is convenient for visiting Helena, The Gates of the Mountains, and other river related facilities. One final word, it’s beautiful to walk up to the overlook in the morning and see the sunrise with fish jumping around the lake.

Our family stayed here a while ago, in our trailer. It was our maiden voyage, and we needed to figure out how the trailer was, and what we might need for longer trips, etc.. First off Black Sandy is a great location, we had a spot literally right on the water in front of the ropes swimming area, and my girls had a blast swimming and enjoying themselves. We had a campfire and roasted marshmallows and enjoyed our time. We had power for our trailer, but I took one star off because there was no water or dump station. The main thing we figured out on this trip was that with two adults and three children, Water is a 100% must. We actually ran out of water in the evening late, and since we only lived a mile away, we drove home. Now we only go where there is full service of electricity, water, and a dump station. For anyone else, though, that doesn’t have so many people, this is an ideal place to take a small vacation and we recommend it highly if you don’t need a water connection.

You can't go wrong with this lakeside park. It has everything you could possible need. Beautiful tent camp spots, nice RV pads, boat slips for $6 night, trees on a black sandy shoreline, fish, a little check in station with ice and incidentals, a camp host to help you after hours, nice bathrooms and views for days. Dog and kid friendly, wheelchair accessible to most areas, and very friendly parks officials.
