Iceberg Boulder is a climbing area in Joshua Tree National Park in California, managed by the National Park Service. It sits among a cluster of other climbing spots, with Boortemus Clump and parts of Corral Wall all about 0.2 miles away. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Joshua Tree show April highs around 77°F and October highs around 82°F, while July and August average about 100°F. That station sits roughly 600 feet lower than this area, so temperatures here run a little cooler. A fee is charged for park activities, so plan for that when you go.
