    Mallory Cave Trail

    Overview 
    Amenities 

    Did you know that Boulder has a bat cave? It's true, and the hike to it is filled with challenging climbs, pine forests and beautiful views.
    At the trail's terminus is Mallory Cave, a bat roosting habitat that is guarded against human entry by a rather artfully designed iron gate. Be aware that there is also a seasonal buffer around the cave that means the last climb up to the cave's gate is closed April 1-October 1 each year. These measures protect the rare colony from white-nose fungus infection, which is deadly to bats.
    The terrain of this trail is steep, heading up the mountainside for spectacular panoramas, and the last section is a serious scramble. 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.”
