This is a great cliff that is virtually unknown to most MA climbers. The rock quality is great. There are long 100 foot routes. Access is the issue. You have a bit of a hike unless someone knows a better way in.
It is in Monson, MA. Take exit 8, the Palmer exit off Rte 90 to Rte 32 south. I've heard that there is access off Bunyan Road, but don't take this as fact. Ask permission to cross anyone's land. You may be able to go in the back way to the top of the cliff by going in the hospital grounds and parking where there is a gated dirt road and walk in that way.
I'm not sure of the access issues at this time. I've only gone in with Ken Nichols who has a key to the gate off Macomber Road. I haven't been there lately. I heard that you can walk in via Bunyan Road, but you have to cross someone's land, so you have to ask permission.
It has been reported to me that the access from Bunyan Road is not an option. The landowner has been leaving notes on the windshields of people parking there, so please do not park there. If you can figure out how to get access from the top/back of the cliff via the former state hospital property, then please let me know. According to plat map lines on Google, the land is owned by whoever owns the former hospital property.
