This route is the shortest on access to the top of Bear Mtn, aka Perkins, via Metro North.
Manitou is a stop on most outbound trains from GCT on weekends, please check that it is on the train you are planning on using. You can only exit the train in the last 2 cars of the train at Manitou. And there is no platform so you need to carry your bike down steps, a rather awkward maneuver. If this does not work for you, you can take the train one stop further to Garrison and go south on 9D, cycling the extra distance.
