• Zoo Ave / Rescate Wildlife Rescue Center: ethical wildlife encounters
• Grecia & Atenas: colonial towns famous for "best climate in the world"

What to Pack for Central Valley
• Light layers (mornings cool, days warm)
• Light sweater or fleece for evenings
• Rain jacket year-round
• Comfortable walking shoes
• Camera — Poás crater views are dramatic
• Sun protection — UV is strong even when cool
• Light scarf for windy crater rim
• Day pack for waterfall trails
San José Airport (SJO) Tips
SJO is technically in Alajuela, not San José city. Most travelers spend at least one night nearby:
• Hotels in Alajuela city: 10 minutes from airport, walkable downtown
• Hotels in San José: 30–45 minutes (traffic dependent)
• Best for early flights: Hampton, Hilton Garden Inn, Country Inn — all <10 min
• Avoid renting a car the same day you arrive on a long flight — fatigue + unfamiliar roads
When to Visit
• December–April: clearest volcano views
• May–November: lush coffee fincas, occasional clouds at Poás
• Visit Poás before 10 AM for the best chance to see the crater (clouds roll in mid-morning)
