Visiting San José
Costa Rica's capital sits in the Central Valley at about 1,150 metres, so it is milder than the coasts. Most travellers pass through on the way to the cloud forests, volcanoes and the Pacific and Caribbean beaches.
Best time to visit: December to April, the dry season, when San José and the Pacific coast get the most sunshine. May to November is the green season, with afternoon showers; the Caribbean coast has its own pattern and is often drier in September and October.
Landmarks & highlights
- National Theatre
An ornate 19th-century theatre in the city centre, with a café inside.
- Pre-Columbian Gold Museum
Gold objects made by the region's Indigenous cultures, under the Plaza de la Cultura.
- Mercado Central
A covered market with sodas (small eateries), spices and coffee.
- Poás Volcano
An active volcano with a steaming crater, a day trip from the city.
Local tip: Go up the volcanoes early in the morning — clouds often roll in and hide the craters by late morning.
Getting around: The centre is walkable; buses and shuttles connect San José with most destinations, and a 4x4 helps on rural roads in the green season.
Good to know: In the green season, mornings are usually sunny and the rain tends to come in the afternoon, so plan outdoor activities early.
