Washington is beautiful year around. The highways across the Cascade Range will be open in June, which is an excellent time for fishing lakes, but streams may be high and discolored. As much as I love this state, the Canadian Rockies in August may be a better choice. They're amazingly beautiful, and high mountain lakes will be open. The Bow River, which flows through Calgary, is one of the great trout rivers in North America.
