Almirante Marcos A. Zar Airport is just outside Trelew and is the main air gateway for both Trelew and Puerto Madryn. Taxis, remises, and rental cars connect the airport with the city and the coast.
Long-distance buses link Trelew with Puerto Madryn, Gaiman, Rawson, Comodoro Rivadavia, and Buenos Aires. If your real goal is Madryn's wildlife coast, check transfer times before assuming Trelew is only a quick stop.
