Costa Rica is famous for beaches, rainforests, and those adorable little smiling sloths. But have you thought about Costa Rica’s waterfalls? As a tropical country, Costa Rica sees a lot of rain–about 100 inches per year. In the mountainous regions (hint: where the rivers start) that can jump to 25 feet a year in some places! All that water makes for plenty of crystal clear rivers and some pretty impressive waterfalls.
