Finding free things-to-do in Costa Rica is almost as easy as bypassing the hotel tour desk touts and traveling just a little bit off the beaten track. Save your precious colones for spending on cervezas and souvenirs, there are plenty of things-to-do in Costa Rica that are free. Beyond sunbathing, hiking, and bird-watching there are nature walks and national parks. Visit the historic ruins and the Basílica de Nuestra Senora de los Ángeles in Cartago, and seek out the Costa Rica Craft Brewing Company to enjoy free beer tastings. Discover the natural charms of the Caribbean coast, feel sand dollars wriggling in the black sand beneath your feet in the waters of Playa Negra.
A self-guided walking tour of the capital city of San Jose yields plenty of free things to do: check out the exceptional street art that adorns nearly every Avenida, and if it's a Monday, entrance to the Costa Rican Art Museum is free. Browse the vintage stalls and get lost in the aisles at Mercado Central. If it's holiday time, you can partake in the fun of Festejos Populares, and ask around for a Tope, a Costa Rican horse parade that's free to see.
