International flights arrive at Aeropuerto Internacional El Catey, located 8km west of Sánchez and a 35-minute taxi ride (US$70) to Las Terrenas. Air Canada, Westjet and Air Transat, among others, serve Canadian destinations; XL Airways goes to Paris. There's also a handful of charter flights.
For Santo Domingo, Las Terrenas Transportes operates direct coaches via the main highway (RD$375, 2½ hours, 5am, 7am, 9am, 2pm and 3:30pm), Puerto Plata (RD$325, three hours, 6:30am), Santiago (RD$320, three hours, 6:30am, 8:30am and 12:40pm) and Nagua (RD$150, 1¼ hours, 7am and 2pm). Buses leave from the Esso gas station on the outskirts of town, 2.5km south of the sea.
Guaguas to Samaná leave in front of Casa Linda at the corner of Calle Principal and the coastal road eight times daily (RD$100, 1¼ hours, 7:15am to 5pm). For those going to El Limón, 14km away, guaguas leave from the same stop (RD$50, 35 minutes, every 15 minutes from 7:15am to 7pm).
For Sánchez, guaguas leave from the Uchotesa depot on the outskirts of town (RD$70, every 20 minutes, 7am to 6pm).
Las Terrenas is easily accessible by road if you’re motoring on your own. A portion of the US$150-million Blvd Turístico del Atlántico connects Las Terrenas with Aeropuerto Internacional El Catey, 24km to the west, avoiding the former need to transit through Sánchez. The toll charges, relative to kilometers, are high (RD$528), and it hasn't exactly been embraced by locals, but it’s a beautiful drive all the same.
