The summit of Great Blue Hill can be reached by hiking or biking from the Trailside Museum and Blue Hill Ski Area parking lots on Route 138. Join us to learn about meteorology, weather instruments, the history of the oldest continually operating weather Observatory,
or just to enjoy the beautiful, panoramic view from one of the highest points in eastern Massachusetts!
The Blue Hill Observatory is located at the summit of Great Blue Hill on the Blue Hills Reservation at the junction of Routes 93 and 138 about 10 miles south of Boston. The closest parking is at the Blue Hill Ski Area or the adjacent Trailside Museum at 1904 Canton Avenue in Milton, MA. Hiking trails lead to the summit from these parking areas. The summit access road is not open to public vehicles; the walk up the hill to the Observatory along the summit road is approximately one mile. Trail maps and information are available at the Trailside Museum.
