With a shore that stretches on for 40 miles and a total surface area of more than 7,000 acres, Lake Granby is truly a sight to behold. The modern Lake Granby was created along with the Granby Dam in 1950, but the lake had a boating presence even before it grew with the damÃ¢ÂÂs creation. Since 1902 the lake has been home to the Lake Granby Yacht club. The club is home to ColoradoÃ¢ÂÂs most committed sailboat racers. If youÃ¢ÂÂre not looking to join a yacht club, you can rent or charter a boat at the Indian Peaks Marina, Beacon Landing Marina, or Highland Marina. With a lake the size of Lake Granby, there are plenty of options to choose from!
