The Most Complete Part of the Dominican Republic! This is why!
I have been living here since 2020 and had previously visited the island on 4 occasions
From Santo Domingo if you do not have a car you can get a bus from the city center (ish) with Caribe Tours, just Google them. Very cheap and comfy, takes about 3 hours to get to Samaná from Santo Domingo. Cayo Levantado is highly recommended. You can even stay on the island, there is a 5-star hotel, where you have to stay for at least 3 nights, $500 a night, all-inclusive, and it has its own private beach as well.
