Upper Chaos Canyon is a climbing area in Rocky Mountain National Park, within the Rocky Mountain National Park Wilderness, on land managed by the National Park Service. It sits in the park's backcountry, and a fee is charged for visits. Summer is the most comfortable time to go. Typical averages from a nearby weather station show July highs around 68°F with lows near 43°F, and September highs around 59°F with the fewest wet days of the year. That station sits about 800 feet lower than the canyon, so temperatures here run cooler. Climbers will find Creme Fraiche Boulder about 0.1 mile away and Hallett Peak - ice/mixed/snow about 0.3 mile away. Hikers can take the Lake Haiyaha Trail, about 0.7 mile off, or the Flat Top Mountain Trail, about 1.1 mile away.
