Birthday Boulder is a climbing area in the Hahns Peak-Bears Ears Ranger District of Medicine Bow-Routt National Forest in Colorado, on land managed by the Forest Service. Summer is the most comfortable time to climb here. Typical averages from the nearby Walden weather station put July highs around 76°F with lows near 38°F. The station sits at about the same elevation as the boulder, so those figures are a fair guide, though nights stay cold even in midsummer. The Right Wing and Main Amphitheater climbing areas are each about 0.6 miles away. Seedhouse Campground, about 1.8 miles off, makes a convenient base, and the Hinman Creek hike starts about 0.8 miles away.
