The Thousand Islands constitute a North American archipelago of 1,864 islands straddling the Canada–US border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. In New York, there are 15 state parks, several nature preserves, and quiet waterside roads. On the Canada Side, the Parks of the St. Lawrence is a group of historic and recreation sites along the river, including Thousand Islands National Park, 21 different islands, and the 1000 Islands Parkway. Since this is a large geographic area, it’s challenging to provide a comprehensive guide to running in the Thousand Islands. We’ve tried to showcase some of the best spots, including quiet waterside roads and gentle trail running in the numerous parks.
This 1,000-acre state park in Henderson is the former estate of Robert Wehle, and consists of 10 miles of wide, scenic trails along Lake Ontario, and around the estate grounds. We've mapped a 4.7 mile loop along the Snakefoot Trail.
