I suppose it's the currents (or lack thereof) around Puerto Rico that create the perfect environment for beachcombing. Once it reaches the safety of the coast, it hugs the shoreline and never leaves.
Every beach in Rincon beckons with its beachcombing finds. The best places for seagrass are Sandy Beach and Steps Beach. The best spots for driftwood are Steps and Pools. And the best spots for the most unique shells are Steps and the Landing.
