Little Boulder is a climbing area on county land within the Carter Lake unit in Colorado. It sits among a cluster of other climbing spots, so it works well as one stop in a day of exploring the surrounding crags. The most comfortable months for a visit are typically late spring and early fall. Typical averages from the nearby Waterdale weather station, which sits a few hundred feet lower than the area, run to highs around 68°F in May and 76°F in September, with July the warmest at about 87°F. Several climbing areas lie just 0.1 mile away, including Chain Rock, Big Block and Pocket Wall. For time off the rock, the Sundance Trail is about 2.3 miles away, and the Big Thompson River offers paddling roughly 4 miles out.
