I spent a month in Costa Rica and Puerto Viejo was the best! It is touristy, but what part of Costa Rica isnt? I guess I liked it more than other parts of Costa Rica becuase it is more of a tourist destination for twenty-somethings. definitely go surfing here and eat at “Bread chocolate”. I stayed at Puerto Viejo Hotel which is owned and run by surfers and is made up of like 30 wood cabins/rooms. the atmosphere in Puerto Viejo is very laid back and the reggae music is great! go to reggae night at club bambu and bike to manzanillo. but be careful about walking around at night, especially if you are a girl or are carrying expensive items.
