LRM
La Romana International Airport
Quick answer
The airport for Casa de Campo and Bayahibe, heavily used by cruises and charter flights. From the airport to central La Romana: taxi about $20-25, 15 minutes. To Bayahibe, taxi $30-40.
The airport trick
No intercity bus departs directly from the air terminals. The right pattern is: short ride from the airport to the bus stop, then the intercity guagua. Guagualine solves both pieces in a single booking.
