    Mallory Cave Trail

    • 1850 Table Mesa Dr
      Boulder, CO 80303

    For a few years, this entire trail was closed to protect a rare colony of bats from white-nose fungus infection. These days the trail is open, while the cave at the end is guarded from human entry with a rather artfully designed iron gate. The terrain of this trail is steep, heading up the mountainside for spectacular views, and the last section is a bit of a scramble to reach the cave. Mallory Cave Trail is one of several in a network that leaves from the parking lot of the National Center for Atmospheric Research (NCAR).
    Directions: Use Google Maps for navigation to parking at “NCAR.”
