Sibley Volcanic Regional Preserve

The visitor center has many indoor and outdoor displays and real samples of volcanic rock and other area geology. A self-guided brochure is available that you can use on the volcanic Trail, which contains most of the stops on the self-guided volcanic tour. There are about ten miles of trails including a trail leading up to Round Top (elevation 1763 ft.) that is made up of lava and volcanic debris left over from a 10-million-year-old volcano. There is a bathroom and drinking fountain by the visitor center.

Operating Hours

Open from 7 AM to 6 PM (winter months) or 10 PM (summer months).

Disabled Access

Round Top and Quarry roads are paved and there is a 600-foot, paved wheelchair path north of the visitor center that ends at a viewing platform.
