Since Costa Rica is famed for its astoundingly diverse range of native species, getting up close and personal with nature is well worth it. The country's national parks are the best places to engage your wild side during your Costa Rica honeymoon. Sitting on the southwest coast, Cahuita National Park is a gorgeous marine park with access to the country's best coral reefs. For more dramatic landscapes, visit the Arenal Volcano National Park, accessible from Monteverde. Admire the active volcano itself, hike across mountains, and even relax in natural hot springs amid stunning scenery.
