About 2 million people in the metro area.

San Jose is the capital and biggest city of Costa Rica, sitting high in a green valley between the mountains. It is the busy heart of the country, full of museums, markets, and friendly people.
You can see shiny gold treasures at the Pre-Columbian Gold Museum, watch a show at the fancy National Theater, and taste tropical fruits at the Central Market. Kids love the Children's Museum inside an old castle-like fort.
San Jose is packed with museums, including the Gold Museum and the Jade Museum, where you can learn about the people who lived here long ago.
Try a plate of gallo pinto, the tasty rice-and-beans breakfast, or a sweet fried banana snack from a market stall.
