The Thousand Islands constitute a North American archipelago of 1,864 islands straddling the Canada–Unite States border on the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. The region is steeped in history and is a popular vacation destination, especially in summer, for boating, fishing, camping, cycling, & more. In New York state, there are 15 state parks, several nature preserves, and quiet waterside roads. In Ontario 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, which includes 21 islands, and the Thousand Islands Parkway. Our guide to running in the Thousand Islands region is focused on the most visited towns, scenic waterfront roads and paths, and some of the best trails.
On the U.S. side in New York, there’s some lovely waterfront running in historic communities on Wellesley Island, and in Clayton, Cape Vincent, Point Salubrious, and Sackets Harbor. On the Canada side, there are some terrific multi-use paths, including the Waterfront Trail alongside the Thousand Islands Parkway and near Upper Canada Village. We also love running on the scenic Long Sault Parkway, which crosses 11 islands. We’ve also provided recommendations on good running spots in the gateway towns of Gananoque and Brockville. We also have a separate running guide for the city of Kingston.
Notes: Remember to bring your passport! Also, although the Thousand Islands is popular summer destination, it’s also a good spot for winter running lovers, owing to the area’s cold winter temps and copious snow.
