Ground options include shuttle and private car services, ride‑hail and taxis (fares typically in the mid‑teens to low‑forties USD), Amtrak/commuter rail connections at nearby Baltimore Penn Station via shuttle or light rail, and the convenient MARC train from certain suburbs. Pros: generally easier parking, lower fares, and a straightforward layout; cons: can be busy during peak times and is farther than some inner‑city heliports or smaller airfields for quick hops.
