Currency
The local currency in Costa Rica is the colones (prononced like "co-loan-nays" with the emphasis on the "loan"). US dollars are welcome everywhere as are travellers checks (in US funds). CAUTION: Make sure that your US bills are immaculate - the smallest defacement (for example, a rip, a mark, a pen mark or any writing, etc.), makes the bills unacceptable except perhaps at large banks in San Jose (but who would want to spend a couple of hours waiting around a bank on a beautiful day). In complete contrast, The Costa Rica treasury gets every last mile out of the colones bills - they may be mere tattered fragmentary remnants of the original bill but nevertheless they are readily accepted in transactions. The closest bank machine is located in Nicoya which is about 1.5 hours away by car from Nosara. Check the different banks in Nicoya for the banking system that you normally use (for example, CIRRUS, Interac, etc.). Another caution re travellers checks - make certain your signature is totally repeatable. We have seen folks unable to cash their travellers checks due to some small variations in their signatures.
As an example, the exchange rate in March 2001 was as follows:
| Date of Exchange | Rate (colones per US Dollar) | |
| March 2001 | 321 | |
| August 2002 | 364 | |
| March 2003 | 375 | |
| September 2003 | 400 | |
| April 2004 | 425 | |
| July 2004 | 440 | |
| February 2005 | 465 | |
| February 2006 | 500 | |
Below is a picture of a crisp new 5 colones bill - this was a commemorative issue.
The inflation rate in Costa Rica is approximately 12% per annum.
