Most international flights to the Dominican Republic will go to Las Americas International Airport (SDQ) in Santo Domingo. This is where you want to go. (Unless you can get a flight into El Catey Samaná Airport which is closer to the villa, but has minimal flights)
If you’re arriving the day of the retreat we’ll have a private car waiting to pick you up at SDQ airport at a designated time. From there it’s about a 2 hour and 20 minute drive to our retreat house in Las Terrenas (It’ll be worth it for the views & beaches!)
