Puerto Cocos, located in Chatham Bay on Cocos Island (Isla del Coco), is the primary logistical access point to one of Costa Rica's most remote and prestigious national parks. Situated far offshore in the Pacific Ocean, this natural harbor serves mainly as a base for scientific expeditions, park rangers, and authorized diving vessels. As the island is a UNESCO World Heritage site, economic activity is strictly limited to regulated eco-tourism and marine research. The port provides essential shelter for ships monitoring the region's vast biodiversity or conducting patrols against illegal fishing. Geographically, the bay is characterized by steep cliffs and dense tropical rainforest, making access to the island's interior challenging. Historically, Chatham Bay was a renowned anchorage for pirates and whalers, many of whom left inscriptions on the rocks that remain visible today. Today, Puerto Cocos stands as a symbol of Costa Rican maritime sovereignty and its global leadership in conservation. Infrastructure is purposefully kept to a minimum, consisting of a ranger station and small piers, to maintain the island's ecological integrity.

This protected anchorage on the remote Cocos Island serves as a safe haven for research vessels and occasional tourists. It plays a key role in the logistical access to the island's National Park.
Visiting
The anchorage is accessible to visitors only through authorized diving or research expeditions, as the island is strictly protected. From the sea, the bay is clearly visible when passing by boat.
Where to view it

Local products
There are no permanent settlements or markets on the island; typical 'products' are the unique marine fauna seen while diving. Researchers occasionally collect endemic plant samples, but these are not for trade.
Active season
Activity in the bay concentrates during the dry season from December to April, when the sea is calmer and more expeditions take place. In the rainy season, the anchorage is often unused as conditions are risky.
