Cocos Island is a popular year-round liveaboard destination in Costa Rica. Known as the mecca for big animals and advanced blue water diving, Cocos Island does not have coral reefs and is not suitable for beginner divers or snorkelers. Instead, Cocos Island is the perfect place for experienced divers to check off bucket list items including scalloped hammerheads, silky sharks, wahoo, tuna, billfish, and dolphins.
There are a few excellent liveaboards catering to scuba divers looking to experience the dive trip of a lifetime to Cocos Island.

DIving season
The diving season in Cocos Island is year-round, and the best time to dive depends on what you're hoping to see. The best time for silky sharks, dolphins, and mobulas is December to May, during the dry season, and you can expect calmer waters and smoother crossings. June to November is the rainy season, when you can expect a lot of rain and rougher crossings but also hammerheads in large numbers.
