Currency
Costa Rica's national currency is the colon, which was named after Christopher Columbus. Although the situation is not as favorable as it is in Ecuador, South America (where the US dollar is the national currency), US dollars are accepted in numerous locations around the country. This is absolutely one of the things to know before traveling to Costa Rica.
As a result, the unavoidable question of whether to pay in dollars or colones. And the solution may be simpler than you think. Many travel companies, tour operators, hotels, and even restaurants charge in US dollars, eliminating the need to worry about currency rates.
Having said that, always double-check the conversion rate before paying with US dollars in Costa Rica, since it might be unfavorable at times. ATMs may be found almost everywhere in Costa Rica's tourist regions (except in rural locales), and you can usually withdraw money in both colones and dollars.
So, whether you're coming from the United States or just have a lot of them, Costa Rica is a great spot to spend them. Unfortunately, Euros are not frequently accepted in Costa Rica, however you may be able to pay in this money at select establishments.
