Warm-Up Block Two is a bouldering area in Colorado's Arapaho and Roosevelt National Forests, on the Clear Creek Ranger District. The Forest Service manages the land, and the area sits about 1.5 miles from the Cabin Creek weather station, which is at roughly 10,000 feet. The climbing here is all bouldering, with nine routes spread across the block. Grades run from V0- up to V5, with the median around V3. Some of the named routes are Downclimb (V0-), Backside Problem (V2), Chalk Block (V2), and Tap Crack (V4). The area sits right beside Warm-Up Block Three, and Guanella Pass is just 0.1 mile away. Summer is the most comfortable time to go. Typical averages from the nearby Cabin Creek station show July highs around 69°F with lows near 46°F, while winter highs hover around freezing. The station sits a few hundred feet lower than the boulders, so temperatures on the rock run slightly cooler. Clear Lake Campground is 1.2 miles away and Guanella Pass Campground is 1.6 miles away for an overnight base. Silver Dollar Lake and Mount Bierstadt are both within about 2.5 miles for hiking.
