Arch Rock is a climbing area in the South Platte Ranger District of the Pike and San Isabel National Forests in Colorado, managed by the Forest Service. It sits among several other named climbing areas, so it works well as part of a larger outing in the district. The most comfortable months for a visit are typically June through September. At the Cheesman weather station 3.5 miles away, typical July highs reach about 84°F with lows near 53°F, and September cools to around 76°F by day and 43°F at night. That station sits roughly 1,000 feet below the climbing area, so expect temperatures at the rocks to run cooler. Two climbing areas, Metaphysical Wall and Great Warm-Up Boulder, lie just 0.1 mile away. For an overnight stay, YMCA Camo Shady Brook is about 2.5 miles off, and the South Platte River offers river fishing within 3 miles.
