Our week in Costa Rica included zip-lining through a tropical rainforest, white-water rafting down the Pacuare River, and encountering wildlife I’d never seen before—like howler monkeys, coatimundis, sloths, and poison dart frogs. We flew into San José and chartered a small plane to Quepos, in Puntarenas Province, to reach Manuel Antonio National Park. Costa Rica’s vibrant rainforests and pristine beaches are among the most beautiful I’ve ever seen.
