Fodor's Expert Review Catarata Manantial de Agua Viva

This is Costa Rica's tallest waterfall, cascading 600 feet into freshwater pools where you can cool off after a strenuous 3-km (2-mile) hike to the river basin. You're not likely to see other tourists here—it's not one of the more well-known waterfalls. This trek is not suitable for children, the elderly, or those with health conditions. Bring drinking water and wear proper shoes as rocks can be sharp and slippery.
