Sand Bar State Park, State park on Lake Champlain in Milton, United States

Sand Bar State Park is a recreation area featuring a long sandy beach along the eastern shore of Lake Champlain near Burlington. The grounds include swimming zones, a boat rental service, picnic areas with grills, courts for volleyball and horseshoes, and walking paths.

The park was developed in the 1930s when the Civilian Conservation Corps built a stone bathhouse and converted the original swamp into a recreational destination. It was among the first lands purchased under Vermont's state park program, which began in 1929.

The park's name comes from the natural sandbar beneath it, most of which now carries the US 2 causeway toward South Hero Island. The 2,000-foot beach and the CCC-built stone grill, still standing, are the features visitors use and notice most.

Access to the facilities runs along Sand Bar Park Road, which branches north off US Route 2 at the eastern end of the sandbar causeway. The beach itself runs about 2,000 feet (610 m) along the lake, and the park borders the 1,560-acre Sand Bar Wildlife Management Area to the east. The bathhouse interior was only modified for electricity and plumbing.

Most of the sandbar now carries a causeway for US Route 2, so the park occupies only a triangular parcel at its eastern end. The 1,560-acre Sand Bar Wildlife Management Area borders the park on the east, and Sand Bar Park Road runs north from US 2 to the facilities.
