Tanglewood Slab is a climbing area in the Mountaintop Ranger District of San Bernardino National Forest in California, managed by the Forest Service. It sits among several named climbing areas, with Greenhouse and Alpine Rocks just 0.1 mile away and Alpine Rock at the same distance. The area has seven routes, five of which are trad and two sport. The YDS grades range from 5.2 to 5.6, with Go Green, Hi Def and Tevo all at 5.2. Enterprise, the hardest route at 5.6, is a sport climb. The most comfortable months for a visit are typically June through September, when typical averages from the nearby Big Bear Lake weather station run from highs in the mid-70s to about 80°F. That station sits roughly 875 feet lower than the slab, so temperatures here run cooler. Tanglewood Group Camp is 0.8 mile away, and Van Dusen Canyon Spur is 2.2 miles off.
