Where are the biggest expat communities in Costa Rica in 2026?

Escazú and Santa Ana are the clearest first pocket. Multiplaza corridors, CIMA-area clinics, international schools, and English-friendly services pull retirees, families, and soft-landing newcomers into the same western valley belt: Living in Escazú and Where to live in Costa Rica. Facebook housing threads and brunch calendars usually assume that geography: Expat community.

Atenas and Grecia form the classic quieter second valley layer: milder weather, tighter retiree circles, and a drive to capital specialists: Living in Atenas. San José neighbourhoods such as Escalante and San Pedro add walkable food scenes with more Tico mix and less suburban English default: Living in San José.

Tamarindo leads Guanacaste beach density with surf shops, nightlife, and a visible North American and European presence: Living in Tamarindo. Nosara concentrates wellness and remote-work circles with a different social tempo. Jacó sits closer for capital weekenders. Manuel Antonio, Uvita, Ojochal, and Caribbean Puerto Viejo host thinner or more seasonal foreigner scenes that rarely match Escazú week-to-week density.

Americans dominate many English calendars in valley and Guanacaste hubs: Where American expats live. Groups and associations still matter for landing: Best expat groups. Spanish decides depth once you leave Multiplaza or beach-strip English: Making friends and Social life. Cost and tourism markups still reshape whether a dense pocket feels affordable after the first mixer month.
