WA - Wallula Gap and Columbia George. If you like to sail big wind and don't mind colder water come sail the Columbia River. Our favorite spots are Wallula Gap and Three Mile Canyon. The Gap (at Port Kelly) has the most favorable winds for sailing, usually 5 - 25 knots, with many 12-18 knot days and moderate swells (1-4 ft). There is also a small sandy beach/launch area, but no facilities. Three Mile Canyon has a protected inner bay, but tends to blow harder (10 - 30 knots, but at times up to 40 Knots+) and has bigger swells (4 to 10+ feet). Three mile has a boat launch, gravel beach, and Pit toilet. Each area allows for non-hook-up camping.
