Buen dia! Check out this sitio gratis and perhaps these maps will provide you with what you're looking for.
http://www.avenidacentral.com/. This site and
http://www.navegalo.com/, are on my recommended list for excellent Tico sites. This portion of the site
http://avenidacentral.com/heredia/belen/, highlights the pueblo where I live in Belen. The following photo is of Ojo de Agua which is a very famous public swimming park. On Wednesdays many of the local girls go there to sunbath topless. You gotta love CR for all of the extra curricular activities that are available. It costs $1.00 for an all day pass. Tuanis! Tom
