Plan a trip to San Jose, CR

A charming mix of modern buildings and Spanish colonial style architecture, San Jose is a lively, manageable city. Before heading out to Costa Rica’s famed jungles and beaches, experience the culture and charms of San Jose. Spend a morning in the Precolumbian Gold Museum or the Museo de Arte Costarricense and walk through the centuries of Costa Rican art and history. Shop the Galeria Namu for fair trade, authentic Costa Rican arts and crafts, including Brunka masks and jade figurines. Poke around the historic neighborhoods of Barrio Amon and Barrio Aranjuez and see how wealthy coffee growers lived in the late 19th and early 20th centuries.
