✈️ Flight Guide: Detroit (DTW) → San Jose (SJO)

February is active for both departing and arriving travelers. In Costa Rica, February often hosts regional carnivals and coastal festivals such as the Puntarenas Carnival (dates vary) and occasional cultural events and open-air concerts in San José. Outdoor adventure and eco-tourism are at peak in Arenal/La Fortuna and Monteverde thanks to dry weather. On the Detroit side, February traditionally features events like Detroit Restaurant Week, winter arts programming, and regional hockey games — ideal for a final meal before departure. Always check local event calendars for exact dates and book transport and accommodations in advance for festival weekends.
