Costa Rica is incredibly safe, as long as you use good sense. Compared to many of its Central American neighbors, Costa Rica is extremely safe. Its homicide rate is 10.3 people per 100,000, second in the region only to Nicaragua at 8.7. Violence like rape and hate crimes are almost unheard of, even thoughâwhen they do occur to visiting North Americansâyouâre very likely to hear about it on the news.
Best Times to Visit Costa Rica. The best time to visit Costa Rica is from mid-December to April (the dry season). This peak tourist season boasts plenty of sunshine making it an ideal time for exploring rainforests and lounging on beaches. That said, the dry season is the most popular (and expensive) time to visit. Luckily the U.S. dollar goes a long way in Costa Rica no matter the season.
