What prior travelers say
“I absolutely loved my time in San Carlos. The diving was spectacular, with colder water species that I’d not had the opportunity to see either ever or in such numbers (nudibranchs galore, sea hares, sea lions, etc.). The local scene was also great: good food, service, and prices for visitors from the U.S. I can’t wait to get back to discover more of what San Carlos has to offer!”
