J.A. Skinner State Park is more than 400 acres of forest on Mount Holyoke, at the western end of the Holyoke Range. It offers breathtaking views of the Connecticut River Valley. The summit is accessible by road and by hiking trails year-round. The auto road to the summit of historic Mount Holyoke at Skinner State Park is currently open from 8am - 6pm daily. It will remain open daily from 8am 4pm beginning Sunday, September 19, through Saturday, October 16. The auto road and Summit House restrooms will be closed beginning Sunday, October 17, 2010. The road will reopen in mid April, weather and staffing permitting. Walkers are welcome year round. The Summit House, a popular mountaintop hotel in the 1800s, is open for tours and programs on weekends and holidays from Memorial Day through Columbus Day, offering historical displays and special events. The park is named after Joseph Allen Skinner, a wealthy businessman who donated the hotel and land to the state in 1940.

Great clear trails but not well marked, most are not marked at all. I highly recommend having a trail map or this app tracking. We ended up taking other trails inadvertently many time. Some we backtracked from but others we just stayed on. We ended up doing just over half the loop and that was still a nice hike. We enjoyed the changing terrain, chipmunks and many little bridges. it seems as though one could spend a day hiking in there and not hit the same trail twice. This is a great mountain bike trail but we only saw a few out there.
