Caldera, Commercial port in Esparza Canton, Costa Rica.

Caldera is a commercial port on the Pacific coast of Costa Rica with two separate terminals. The facility has multiple docking facilities for containers and specialized areas for different types of cargo.

The port facility was constructed in the 1970s after operations relocated from Puntarenas. Its official opening on December 17, 1981 marked a major shift in how cargo moved through the Pacific coast.

Caldera was Costa Rica's main Pacific port from colonial times until the early 20th century, when cargo was moved by boat between shore and anchored ships. The name passed to the artificial port opened in 1981. Today the terminals handle containers, solid bulk, iron, fruit and vehicles, with the United States and Asia among the main destinations.

The port is directly connected to San Jose via Route 27, offering easy access for trucks and visitors. The location makes it simple to reach the port zone or travel onward to other parts of Costa Rica.

Since 2023 Caldera has served as the eastern terminus of the El Salvador–Costa Rica ferry, a crossing that links the port with Central American neighbours to the north. The same docks handle containers, solid bulk, iron, fruit and vehicles, with general cargo and tuna only marginal. The access channel and anchorage keep a minimum depth of 13 metres over a seabed of sand and mud.
