Bittersweet Boulder is a bouldering area in Phoenix South Mountain Park, on city land in Phoenix, Arizona. It sits among a cluster of climbing spots, with The Arena Area Foo, Warmup Crack and Split Rock Area all about 0.1 mile away. The Siblings Boulder is also close by, and the Guadalupe Perimeter Trail passes within a tenth of a mile. The climbing here is all bouldering, with five routes ranging from V0-1 to V5-6. The most straightforward is "In the Heat of the Night" at V0-1, and the hardest is "Possum King" at V5-6. All the routes were first ascended by Joel Wainwright. Winter and early spring are the most comfortable times to visit. Typical averages from a nearby weather station in South Phoenix show January highs around 67°F and lows near 42°F, while summer highs climb into the low 100s.
