Ollie's Folly is a moderately wide machine-built trail that rolls through open cedar forest on the west side of Duck Pond. The trail is a lollipop, rideable either clockwise or counterclockwise, with riders starting and finishing on the "stick" of the lollipop either direction. There are no sustained climbs, but lots of fun, swooping downhills and bermed corners. A notable highlight is the steep ridge along which the trail snakes for a few hundred meters.
From the eastern end of Square-a-Bit
(or the Round-a-Lot ski trail), turn left and head down Duck Pond towards Murphy's Field. Look for the entrance to Ollie's Folly on your left near a large rock.
