Welcome to Grand Isle State Park, located on South Hero Island in Lake Champlain. The Island, also known as Grand Isle, is 14 miles long and over 3 miles wide, making it the largest in Lake Champlain. It contains the towns of Grand Isle (on the northern half) and South Hero (on the southern half). The North and South Hero Islands are named in honor of early pioneering Vermonters who served in the American Revolution.
Grand Isle State Park is the most-visited campground in the state park system. With 4,150 feet of Lake Champlain shoreline, Grand Isle is popular with many destination campers who spend their entire vacation here. At the same time, the park location on US Route 2 attracts a high number of one-night campers, while proximity to population centers in Burlington, Vermont and Montreal, Quebec make it an easy destination for the weekend or spur-of-the-moment camper. Park property extends all the way west to Route 2, where part of the land is being kept open by agricultural lease, and some of what was pasture thirty years ago has reverted to woodland.
