Scoping out the transportation options in Whippany is a smart way to keep your trip affordable. The closest airport is Morristown, NJ (MMU-Morristown Municipal), situated 2 mi (3.2 km) away. However, if that doesn't suit your budget, you can arrange flights in and out of Caldwell, NJ (CDW-Essex County), which is 8.1 mi (13.1 km) away. Whippany may not have many public transit choices so a car rental could be an economical alternative to explore more of the area.
