To get to this hidden fisherman’s paradise the bus ride is not the easiest one. From David the bus goes to Horconcitos but not too often. From Horconcitos apparently there is another bus to Boca Chica, but this is one bus I never got to see. Luckily a taxi showed up in the bus station and the driver was willing to take all of us for the same price as the bus. If you are not alone it makes sense to take any bus that goes along the David – Santiago route and to ask to be dropped of at the intersection towards Boca Chica. From there you can take the taxi the rest of the way.
The small town of Boca Chica is not a commercial town, and there is not much to do or see if you do not have a boat. If you make it all the way to Boca Chica your best and least expensive option for overnight lodging will be on the nearby island called Boca Brava.
The water-taxi will take you across for $3.00 and the hotel/hostel Boca Brava is located right on the top of the hill from the dock. It has a restaurant with a wonderful view and a variety of accommodations. From sleeping under a roof in a hammock, in a bed in a dormitory or in a standard, deluxe or suite room, it is all there to choose from. The island is home to a variety of wildlife, including howler monkeys. If you walk around you will not miss their loud cry. There are a lot of trails to walk, however the beaches are not the best as the ocean is usually murky. 
Yet, it could be a quiet and restful time if you do not want crowds for a while, as the island is almost totally uninhabited.
