Boulder Canyon Loop from First Water Professional Review and Guide
"This loop ascends from First Water trailhead, climbs through The Garden, then descends through Second Water Canyon to the confluence of Second Water and Boulder creeks. It then follows Boulder Canyon past Battleship Mountain, between Yellow Mountain and the Red Hills, and up into East Boulder Canyon to the junction with Dutchman's Trail.
Finally, it follows Dutchman's Trail back to First Water trailhead. The difficulty of this hike is tied to the water level in Boulder Creek. OUTSTANDING FEATURES, Cholla forests, The Garden, mountain vistas, Battleship Mountain, all manner of granite formations, and a plain right out of a spaghetti western."
