Mark Twain Lake consists of 18,600 acres of surface water and is surrounded by 38, 400 acres of land managed by the US Corps of Engineers. The lake is approximately 27 miles in length and provides 285 miles of beautiful shoreline. This lake is ideal for both sail boating and motor boating and provides fishermen with a variety of fish species. Sailboats began to explore the lake in 1986, not long after it was filled. Many sailboats still roam the lake for fun, racing, and camaraderie. With nearly 12 nautical miles available, the Lake has good accommodations at two marinas, Blackjack Marina, and Indian Creek Marina. You’ll also find campgrounds, picnic shelters, beaches, playgrounds, boat ramps and marinas, along with numerous private facilities offering lodging, dining, shopping and family entertainment.
