Coldstream Canyon River Boulder II is a bouldering area in Donner Memorial State Park, California, within the Truckee Ranger District of Tahoe National Forest. The land is managed by State Park and Recreation, and the boulders sit about 0.1 mile from the Coldstream Canyon climbing area and 0.3 mile from Shadow Boulder. The climbing here is all bouldering, with 12 routes spread across the V0-1 to V6-7 range. The easiest routes sit at V0-1, and the hardest reach V6-7. The area is a compact cluster of boulders rather than a long route, so it works well as a short stop for climbers already exploring the surrounding canyon. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July highs around 82°F with lows near 44°F and only about two wet days in the month. Winter is much colder, with January highs around 41°F and lows near 17°F. Nearby, the Donkey Town Trail and JP's Trail offer hiking within a mile, and Granite Flat campground is about 1.6 miles away. Donner Creek, a paddling spot, is about 2 miles off.
