We strongly encourage taking the Metro to the Natcher Conference Center. There are very few visitor parking spaces at the NIH. There is a three-hour limit on visitor parking spaces, and ticketing is enforced. The Natcher Conference Center is a 5-minute walk from the Medical Center station on the Red Line.

The Natcher Building is located on Center Drive directly behind the Medical Center Stop. The Conference will take place at the National Institutes of Health, Natcher Conference Center, Atrium (entry level) and Auditorium (lower level) at 45 Center Drive, Bethesda, MD 20852.

If you must drive, take the Wisconsin Avenue exit from the Capital Beltway (Rte 495) and go 1.5 miles south on Wisconsin Avenue toward Bethesda to the 5th traffic light at Center Drive/Jones Bridge Rd. Turn right onto NIH Gateway Drive. The Natcher Building is at 45 Center Drive and is located across from the Library of Medicine.

An alternative parking at NIH is to drive to Bethesda and park in a public lot in Bethesda. From Bethesda you can either take the Metro (stop is located at East West Highway and Wisconsin Ave.) to the Medical Center Stop or walk up Wisconsin Avenue to Center Drive (about a 10-15 minute walk). You may also drive and park at other Metro Stops on the Red Line that have public parking and take the Metro to the Medical Center station. Convenient stops include Rockville, White Flint and Grosvenor.

New security measures have been put in place on the NIH campus, affecting both staff and visitors.  For more information, please refer to the

Due to increased security on the NIH campus, a guard or policeman will stop you at the entrance to South Drive and ask for your driver's license and the purpose of your visit.

For those driving to the NIH campus: You will be sent to a parking lot nearby and your car will be inspected. After the inspection, you will receive a visitor pass. Continue down South Drive to the intersection with Center Drive. Turn left, and then makes the third left into the visitor parking lot. This turn is immediately after the turn into the plaza in front of the William H. Natcher Building (Building 45) and just before a large intersection and traffic light.
