Key Features:

  • Moses Spring Trail: This section of the loop begins with a gentle climb through shaded woodlands, leading to the entrance of the Bear Gulch Cave. The trail passes by Moses Spring, a serene water source that adds a touch of tranquility to the hike.

  • Bear Gulch Cave: A highlight of the hike, this talus cave is formed by massive boulders wedged together, creating a dark and adventurous passage. A flashlight is required to navigate the cave, which features narrow passages, staircases, and occasional streams of water.

Best Season to Visit:

  • Spring (March to May): This is the ideal time to hike when the weather is mild, wildflowers are in bloom, and the reservoir is full. The caves are also more likely to be open during this season.

  • Fall (October to November): Cooler temperatures and fewer crowds make fall a great time to visit. However, check cave accessibility, as seasonal closures may occur.

  • Winter: While winter can be a peaceful time to visit, be prepared for cooler temperatures and potential rain.

  • Summer: Summer can be hot, especially on the exposed Rim Trail. Hike early in the morning or late in the afternoon to avoid the heat.


Trail Tips:

  • Water: Carry plenty of water, as the trail can be hot and dry, particularly on the Rim Trail.

  • Cave Accessibility: The Bear Gulch Cave is occasionally closed to protect bat populations, especially during pupping season (typically May through July). Check the park's website or visitor center for current cave conditions.
