Tonnere Tower is a climbing area in the Boulder Falls area of the Boulder Ranger District of the Arapaho and Roosevelt National Forests, in Colorado. It sits on city land, and the Boulder Falls setting puts it within easy reach of Boulder. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July highs around 79°F with lows near 50°F, while winter highs stay in the low 40s. That station sits about 1,000 feet below the tower, so temperatures at the climbing area run cooler. The Garden and Creekside climbing areas are both about 0.1 mile away. The Hawkins Surguine Spur Trail is about 1.3 miles off, and Winiger Ridge campground is about 4.2 miles away.
