Surfing Central America
This a great area for surf trips: quality surf, secret spots and adverture is what you can expect here. Costa Rica being the most visited by US citizens because of the large variety of quality breaks, like Pavones and Ollie's point.
Costa Rica is also politically one of the most stable countries in this region. Other great places to surf are El Salvador, Panama and of course the Caribbean version of Hawaii: Puerto Rico. Central America can be done on a pretty low budget: some surf camps don't charge more that 25 US dollar. Also plenty of surfing on some of the Caribbean islands like Barabados and Jamaica.
