Reptile Rock is a bouldering area in the Calaveras Ranger District of Stanislaus National Forest in California, managed by the Forest Service. It sits among a cluster of climbing and camping spots, with Other Side of the River Wall and Stanislaus River Campground both about 0.3 miles away. The area has seven bouldering routes, all rated on the V scale from V1 to V7. The easiest are Alligator Lizard and Watersnake at V1, and the hardest is Kingsnake at V7. Reptile Traverse is a V5. The routes are all bouldering, so there is no climbing on rock faces. Summer is the most comfortable time to visit. Typical averages from a nearby weather station at Calaveras Big Trees show July highs around 81°F with lows near 56°F and only about one wet day in the month. That station sits roughly 1,500 feet lower than the area, so temperatures at Reptile Rock run cooler. Winter is cold and wet, with highs in the mid-40s and about 11 wet days a month from December through February. Nearby, Cow Camp is a hike about 1.1 miles away, and Sand Flat campground is about 1.8 miles off. Utica/Union Reservoirs, about 2.3 miles away, offers lake fishing.
