Historic colonial Pacific port ringed by mangroves
A small town on the Nayarit coast with an estuary harbor and mangrove waterways popular for birdwatching boat trips. A modest airstrip serves the area. It remains a low-key fishing port and surf spot.
San Blas was an important Spanish naval port and shipyard in the 18th century, launching expeditions up the Pacific coast toward California. The hilltop ruins of the old customs house and church date from that era.
