Can you go Winter fly fishing in British Columbia? You better believe you can! The temperate climate of British Columbia’s southwest coast lends itself perfectly to year-round fishing, including getting out during the months of December, January & February. Prime time for a trout fishing trip is from mid November to late February. With limited fishing pressure on rivers near Vancouver, Squamish and Whistler, a Winter fly fishing trip is a great excuse to get out and experience some wild places.
