Way Warm-up Slabs is a climbing area in the Mammoth Ranger District of Inyo National Forest in California, managed by the Forest Service. It sits in the high country, about 4.5 miles from the Mammoth Lakes weather station, and its elevation is higher than that station, so temperatures here run cooler. Summer is the most comfortable time to visit. Typical averages from the Mammoth Lakes station show July highs around 78°F with lows near 49°F, while winter highs stay in the low 40s and lows dip to around 17°F. Several other climbing spots and trails lie within a tenth of a mile. Way Warm-up Wall and T J Swan Cliff are both close by, and the Tj Lake Loop mountain bike route starts about the same distance away. For overnight stays, Lake George Campground is about 0.6 miles from the slabs.
