Closed dusk till dawn. Nice low traffic stretch along the ridge line with many nice spots to stop and take in the views, though they are a bit obstructed by the tree line. Its particularly fantastic in autumn. A rewarding mostly flat segment to enjoy the fruits of the climb even if you don't stop.

Brookside Drive is closed to car traffic on Sunday mornings, making it a peaceful ride with views of Campbell's Pond. There's a nice downhill if you start at the north end of South Mountain Reservation.
