How do you get to Cocos Island from Costa Rica?
You get there by booking a liveaboard dive vessel departing from Puntarenas, Costa Rica.
Cocos Island sits 550 km (342 mi) southwest of Puntarenas at coordinates 5°31′N 87°04′W. No permanent residents live there—just diving expeditions and scientific teams. Access is tightly controlled, so private boats aren’t an option.
What’s the geographic context of Cocos Island?
Cocos Island is the only landmass in the eastern Pacific large enough to support cloud forests and rainforests.
Perched on the Cocos Plate, it sits where major ocean currents collide. That creates nutrient-rich upwellings, drawing hammerhead sharks, manta rays, and countless other marine species. Its isolation and strict conservation have kept ecosystems pristine—earning UNESCO World Heritage status in 1997.
What are the key details for traveling to Cocos Island?

Any interesting background on Cocos Island?
Pirates once hid there, and its cliffs inspired Treasure Island.
First mapped by Europeans in 1526, the island later became a refuge for pirates like William Dampier and Benito “Bloody Sword” Bonito. Costa Rica declared it a national park in 1897, though enforcement lagged for decades. Those dramatic cliffs and caves even influenced Robert Louis Stevenson’s writing. Scientifically, the island’s isolation makes it a goldmine for studying evolution—Charles Darwin cited the Cocos finch in his work on adaptive radiation.
What practical information should you know before going?
All visitors must arrive on a liveaboard dive vessel from Puntarenas—no exceptions.
Trips run year-round but are most reliable from November to May. Book 6–12 months ahead; berths and park quotas are tight.
Pack smart: Lightweight, moisture-wicking clothes, a wide-brim hat, reef-safe sunscreen, and sturdy water shoes for rocky landings. Liveaboards handle tanks, weights, and meals—your wetsuit and dive computer are up to you. Power is limited, so bring a power bank.
Permits & fees: Expect a $200 park entrance fee collected onboard. Most operators require proof of travel insurance for diving emergencies. No landing without a certified guide and park ranger escort.
Health & safety: Malaria isn’t a concern, but dengue is a year-round risk. If you’re transiting through endemic countries, get the yellow fever vaccine. Motion sickness is common—ask your doctor about preventive meds before you go.
Follow the rules: Fishing, shell collecting, and touching wildlife are banned. Drones need special permission from Costa Rica’s Ministry of Environment. All waste must leave the island; liveaboards get inspected before departure.
Plan your gateway: Puntarenas is just an hour’s drive from San José’s Juan Santamaría International Airport (SJO). Stay overnight in Puntarenas or nearby Jacó to catch early departures, which dodge afternoon Pacific swells. Park your car in a guarded lot (~$10/day) or take a taxi (~$40 from SJO).
