The "Big Three" Regions
- Arenal / La Fortuna: The adventure hub. Volcano hikes, hanging bridges, waterfall rappelling, and natural hot springs.
- Monteverde: The cloud forest. High altitude, misty trails, zip-lining, and incredible biodiversity (Quetzals).
- Manuel Antonio: The beach & wildlife combo. White sand beaches, easy jungle trails, and guaranteed sloth/monkey sightings.
