Las Galeras is a small village at the far end of the Samaná Peninsula in the Dominican Republic. It's famous for its world class lonely beaches, e.g. Playa Fronton or Playa Rincon. Compared to Las Terrenas, the other major beach destination on the Samaná Peninsula, Las Galeras is a much smaller town, and geared towards a much more low-key kind of tourism. That means it's quieter and more relaxed, but also has fewer services available (in particular, see "Buy" below for important info on getting cash).
Getting there and away without your own vehicle is the difficult part. Public transport is limited, and the road is starting to get a little bumpy again after being paved a few years back. Caribetours  offers transport from Santo Domingo to Santa Barbara De Samana and back six times daily. You can get in at the various stops in between. 4 of the 6 buses take the new highway and bring travel time down to 3 hours. From Samana you will have to take a guagua, a local minibus, which takes another 1 hour. The minibuses leave from the morning to the afternoon (6PM). The easier way to get there is by renting a car in one of the bigger cities in the country. Hereby you can avoid the fairly expensive transport fairs (15 US) later on, when you are planning to spend the day at one of the fabulous but hardly accessible beaches.
