Rabun Boat House (Hall's)
Hall's has been a fixture on the lake since the 1930's. They provide fuel, boat repairs, boat rentals, a convenience store, and boat slips. Also a great place to fill up tubes and large floats with their air compressor.
Annie's At Alley's Market and Deli
A historic general store restored and remodeled in 2009. A great place to grab sandwiches for a picnic lunch on the lake.
Louie's On The Lake
Pizza/Italian and the only restaurant accessible by boat. About a 2 minute drive and similar by boat. To reach them by boat, come to Hall's and dock on the right side of the cove when entering. Walk up the hill and you'll see them.
