Operating Hours & Seasons

Castle Mountains National Monument is always open. Information centers in Mojave National Preserve maintain regular hours of operation.

Mojave Desert experiences change with the seasons.

• Infrequent winter snows sparkle on the mountains.
• With enough moisture, spring wildflowers carpet the desert with vivid colors.
• Summers are hot, so adventurers head for the higher elevations such as Mid-Hills and the New York Mountains.
• The cooler temperatures mark the beginning of fall.
