Driving Directions:

From the northeast - Take 287/87 west across the Tappan Zee Bridge (no toll westward, $5 toll going east) and take the first exit on the other side of the bridge (Exit 10 toward 9W and South Nyack).  Follow signs for 9W south. Continue 7 miles on 9W and the Lamont-Doherty Earth Observatory will be on your left (before you see signs for the Palisades Interstate Parkway).

From the south - Take 95 North until the exit for US 46 E toward the George Washington Bridge and Palisades Park.  Follow signs fro US-9W/Fort Lee/Palisades Pkwy.  Take the Palisades Parkway North until exit 4 (toward US 9W).  At the bottom of ramp, turn left at the light and Lamont-Doherty Earth Observatory will be on your right.


There is usually plenty of parking on the Lamont Campus.  Check the map for the three designated parking locations.  From the furthest lot, it is less than a 10 min walk to Monell.  WHEN YOU REGISTER OR SUBMIT AN ABSTRACT, INDICATE WHETHER YOU WILL BE ARRIVING IN A CAR (DRIVING OR NOT) SO WE CAN NOTIFY THE FRONT GATE.

Public Transportation Options

The Red and Tan bus line (operated by Rockland Coaches) has a stop directly outside the gates of the Lamont-Doherty Earth Observatory.  The stop is called Palisades and is a 40-45 minute bus ride from the Port Authority Bus Terminal at Times Square.

The New Jersey Transit, Amtrak, and Long Island Railroads have stops at Penn Station, NYC which is just 8 blocks from the Bus Terminal.

The Metro North stops at Grand Central Station, an easy subway ride on the 7 or S trains to Times Square.

The Lamont Shuttle that runs from Columbia's main campus to the Lamont campus is located on W 120th St between Broadway Ave and Amsterdam Ave (in front of Columbia's Teachers' College).  If it is easiest for you to get to W 120th St, we can provide limited shuttle service from this location.  IF YOU CHOOSE THE SHUTTLE OPTION, PLEASE TELL US WHEN YOU REGISTER OR SUBMIT YOUR ABSTRACT TO GUARANTEE RIDES FOR EVERYONE.
