Rincon
Rincon is a town located on the west coast of the Puerto Rico between Aguadilla and Mayaguez, looking out over the Mona Passage towards tiny, uninhabited Isla Desecheo. There is a moderately well established tourist/hospitality business around the edges of the town, along the 413 highway and down along the coast.
The community is composed of local Puerto Ricans with a smattering of international surfers, Americans and other nationalities who came to surf the legendary waves after they were popularized when the world surfing championships were hosted there in 1968. Locals are friendly to tourists, but it can be very helpful to have a command of conversational Spanish.
Get in
Coming to Rincon is not a Disneyworld experience, and might be difficult or frustrating for people travelling with small children. It will be necessary to rent a car to get to Rincon. Rincon isn't clearly marked on that map, but it's southwest of Aguadilla, at the point on the west coast.
Get around
You will need a car to get to restaurants/ bars/ surf shops/ beaches, as there are no sidewalks next to the steep, narrow roads that connect downtown with the surf breaks. It is possible to rent rooms in a hotel or a private house that is right on the beach, but at some point you will probably need to drive somewhere and there don't seem to be any local ground transportation services.
Do
Downtown Rincon is about 5 minutes away from many beaches which enjoy surfable waves throughout the winter months, on both the north-facing and west-facing coasts. There isn't a whole lot to do here except surf or hang out on the beach.
Drink
The bars conveniently stagger their happy-hour events, so that you can go to Nativo at 5 on Monday night, and when their happy hour ends at 7, you can head on down to tamboo and keep drinking until they kick you out.
Sleep
The hotels generally have less than 20 rooms. Some have pools and restaurants/bars, and none of them are more than 5 minutes away from a beach.
