Hand Grenade Corridor is a climbing area in Joshua Tree National Park in California, managed by the National Park Service. It sits within the park's boundaries, and a fee is charged for visits. Spring and fall are the most comfortable times to go. Typical averages from a nearby weather station in Twentynine Palms show March highs around 74°F and November highs around 72°F, while July and August average in the mid-100s. That station sits well below the park's higher ground, so temperatures at the corridor run cooler. Several other climbing areas lie just 0.1 mile away, including Wooly Spider Boulder, Stirrup Tank and Pyramid Tower and The Stirrup. For a hike, the Hexehedron Main Trail is about 2.4 miles off.
