Accessibility:

The pedestrian route from the parking lot to the observatory along the summit road is approximately one mile in length, with an average slope of 15-20%. This road is not open to public vehicles. Special arrangements can be made for specific vehicles to drive to the Observatory. If you have concerns about reaching the Observatory, please contact Program Director Don McCasland.

Blue Hill Observatory is over one hundred and thirty years old, and was built in several stages on top of the hard granite hilltop. The route up to the tower includes steep slopes up to 18% and rocky natural terrain. Once inside, many of our public rooms are accessible to guests with limited mobility, but there are some areas that can be reached only by steps, including the observation room and higher spots in the tower. Many of the exhibits within the Observatory can be moved to accessible areas, and accommodations will be provided for those who do not wish to or cannot travel to the upper rooms.

The hilltop around the Observatory is rocky and uneven in many places, with steep slopes and abrupt changes in level. Accommodations will be provided for those who do not wish to or are unable to navigate the hilltop.
