Why I Love Puerto Rico's Natural Wonders

Did You Know?

Puerto Rico has more than 1,300 rivers and streams, yet not a single river is long enough to be navigable by large boats. Because of the island's mountainous terrain, most rivers are relatively short but descend quickly, creating waterfalls, rapids, and dramatic valleys before reaching the coast.
