Land transportation from the airport to West Point is available by taxi or limousine. Information can be obtained at the airport. Public bus from Newark to West Point is not recommended. It is possible to have special charter buses arranged, but that would have to be decided by each class in their reunion planning. If you come into Newark, it probably would be best for you to rent a car.
Cabs are available to West Point.
