Sandy Beach sits in the day use area of Pickwick Landing State Park, on the south shore of Pickwick Lake in Hardin County, Tennessee, a short distance upstream of Pickwick Landing Dam. Tennessee State Parks runs the park, which covers about 1,400 acres of the land the Tennessee Valley Authority once used to house the crews that built the dam in the 1930s. TVA still owns and operates the dam and the reservoir behind it, so the water you swim in is managed on a schedule set by a power and navigation agency rather than by the park.

The park has three public swimming beaches. Sandy Beach and Circle Beach are both in the day use area, and the third is across the lake at the Bruton Branch primitive area. Sandy Beach is the one to aim for if you want facilities, because the park puts a restroom near it while the other two get a porta-potty. Picnic Shelter 2 stands directly above the sand with a fire pit, water, electric, adjacent restrooms, parking and a lighted flag pole, and the point looks out over both the lake and the dam. Circle Beach is a short distance east, built around a circular turnaround drive with a volleyball court, and it splits into two separate swim areas.

Nobody is watching the water. The park states plainly that swimming is not supervised at any of the three beaches, and it asks visitors to swim only in designated areas and to be aware of the spillway and the generator schedule at the dam. Six generating units and a set of spillway gates sit less than a mile downstream, and they can change the current with little warning. Alcoholic beverages are not allowed anywhere in the day use areas.

Getting in costs nothing. Like every Tennessee state park, Pickwick Landing is free to enter, and the beach and its parking carry no fee. What costs money is anything reservable. Shelter 2 averages 200 dollars, and the larger Sandy Beach Point and Pavilion 2 venue averages 625 dollars and includes the parking area. For an additional fee a renter can close the adjacent beach area to other park guests, so a summer Saturday can be booked out from under you. The park office is open 8 a.m. to 4:30 p.m. daily, and the gift shop at 120 Playground Loop is open 24 hours. The two swimming pools belong to the lodge and are open only to lodge and cabin guests.

Water level is what changes this beach most. TVA holds Pickwick Lake between 413 and 414 feet through the summer and draws it down to a minimum of 408 feet for winter to keep navigation depth and open flood storage. That swing of roughly six feet widens the sand and pushes the waterline well out from the shelter in the cold months, then brings it back up toward the grass by early summer. At full summer pool the reservoir extends 53 miles south from the dam, covers 43,100 acres and carries nearly 490 miles of shoreline.

Camping is in an odd state right now. The main 48 site campground is closed for recent weather damage and upcoming renovations, with no reopening date posted. The Bruton Branch primitive campground on the north side of the lake stays open year round with 32 sites, many of them on the water, plus a bathhouse, playground, boat ramp and the park's third swimming beach. The marina sells gasoline and diesel at a full service dock, keeps two public launch ramps open all year, and rents pontoons, canoes, single and tandem kayaks and stand up paddleboards. The park keeps a free all terrain wheelchair, an accessible boat dock and an accessible kayak launch, and there is a 2.8 mile trail system plus a lodge, cabins and an 18 hole golf course on site.
