The Main Cliffs are a climbing area on city land in Colorado. The surrounding area has several other spots within a short walk, so it works well as a cluster of options rather than a single destination. Summer is the most comfortable time to visit. Typical averages from a nearby weather station run from highs around 73°F in June to about 79°F in July, with lows in the 40s. Winters are cold, with January highs near 39°F and lows around 17°F. Pebble Beach and Sacred Cliffs are both climbing areas about 0.1 mile away, and the E.M. Greenman Trail is a hike at the same distance. Pebble World, another climbing area, sits about 0.3 mile off.
