I've grown up going to Montgomery Bell State Park and have been camping there for 23 years. The campground has water and electric hookups, space for RVs, and bathrooms with showers.
The campground is adjacent to a creek and a baseball diamond. In addition to these features, the park offers a lake for boating as well as a roped off swimming area and man-made beach. Next to the lake is the park lodge which includes a restaurant, meeting rooms, and a swimming pool. The lake also has a picnic pavilion with restrooms.
The park was built on an historic home site so there is an old chapel (which still has services) and an old log home as well as a small family cemetery. There are also a number of hiking trails, a suspension bridge, and very nice, modern cabins available to rent.
Some friends and I camped at Standing Stone during the 2017 Solar Eclipse. The state parks in Tennessee all hosted special programs for the event, and Standing Stone park rangers invited everyone to row out on the lake to watch this magnificent phenomenon. They provided boats and life jackets for everyone who registered and made sure everyone made it out on the water in time. The park also provided everyone with takeaway bags that included eclipse glasses and commemorative swag.
The campground and facilities included water and electric hookups as well as bathrooms with showers. Dogs are allowed as are camp vehicles.
The park has lots of great hiking trails, a playground, and a pool with concessions.
At the end of our trip, my car battery died and we called the park office. Within minutes, a park ranger arrived to jump me off. I can't say enough good things about this park.
