#3 of 15 in Things to do in Alexandria Bay
The Thousand Islands constitute an archipelago of 1,864 islands that straddles the Canada–US border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. They stretch for about 50mi downstream from Kingston, Ontario. The Canadian islands are in the province of Ontario and the U.S. islands in the state of New York.The islands range in size from over 40sqmi to smaller islands occupied by a single residence, or uninhabited outcroppings of rocks. To count as one of the Thousand Islands, emergent land within the river channel must have at least 1ft2 of land above water level year-round, and support at least two living trees.GeographyThe Thousand Islands archipelago is located at the outlet of Lake Ontario at the head of the Saint Lawrence River. The region is bisected by the Canada-United States border and covers portions of Jefferson and St. Lawrence counties in the U.S. state of New York, in addition to parts of the United Counties of Leeds and Grenville and Frontenac County in the Canadian province of Ontario.

  • A magical place of more than 1000 small, small islands in the st Lawrence river ,sharing the boarder of America and Canada.German style Boldt castle and Singer castle are worth to see.
  • Basically as the name says, a group of more than a 1000 islands. Every small land mass or rock above water is counted as an island :) But it is definitely worth a visit. The islands and houses on them are very beautiful. Take a ganonoque cruise from the canadian side, the boat will take you around all of them with some good commentary. There is one small island with a tiny bridge that crosses Canada/US border!!
  • I felt when i was over a boat cruising those islands like I was in magic land πŸ˜‚ so niceπŸ˜πŸ‘πŸ‘πŸ‘πŸ‘
  • The most wonderful Islands I have ever seen.
  • Naturally created 1864 small islands between Canada & USA. There is a smallest bridge connecting two countries.
