World Boulder is a climbing area in Phoenix South Mountain Park in Phoenix, Arizona, on city land. It sits among a cluster of other named climbing spots, with The Big Roof, Africa Boulder and The Amphitheatre all about 0.1 mile away. That makes it easy to combine with a visit to one or more of the neighboring areas. The area is a bouldering destination, with 21 boulder routes and one top-rope route among its 22 listed routes. The boulders range from V0- to V7 on the V scale, with Limited Choss, Slick Trip and Arrowhead on the lower end and Coyotes Choice at V7. That mix suits climbers of all experience levels. Winter and early spring are the most comfortable times to visit. Typical averages from a nearby weather station in South Phoenix run from highs around 67°F in January to about 78°F in March, while summer highs there reach the low 100s. The station sits roughly 636 feet lower than the park, so temperatures at the climbing area run a bit cooler. The Young Man Trail is about 0.4 mile away, and the Mormon Loop Trail and Guadalupe Perimeter Trail are each about 0.5 mile away for anyone wanting to pair climbing with a walk.
