Take I-80 to Exit 43. Take I-287 south, toward Morristown, for 11.8 miles to Exit 26B for Bernardsville. Travel north on Childs Road.
Sanctuary parking is one mile on right.
It is bounded by Morristown National Historical Park. Trails lead from the sanctuary to this historic park. This area is south of the area that was covered by the most recent glacial advance. There are not the ice-polished outcrops seen in the Ramapo Mountains to the north. The soil along the ridge here is deeper, not having been scraped away by the glacier.
