Parking is available at the designated trailhead lot. No public transport directly serves the site; private vehicle is the primary access method.

Historical & Ecological Origin

The Cobble is a geological feature formed by the uplift and erosion of ancient sedimentary rocks, primarily limestone and quartzite, dating back millions of years. It represents a significant exposure of the Stockbridge Limestone formation. Ecologically, it supports a unique microclimate and habitat for specialized flora, including several rare and endangered plant species.
