Together Treasure Valley Dog Island

Address: 3417 Crescent Rim Dr, Boise, ID 83706

Water surrounds this Boise off-leash island, acting as a natural boundary while giving dogs the chance to swim alongside more traditional park amenities. Separate large and small dog areas, shade, benches, waste bags, trash cans, restrooms, and a parking lot make it one of the more fully equipped options in the area. Mud accumulates after winter rain, and some visitors have raised questions about water quality, so conditions vary by season.
