About this swimming hole
Moonstone Beach is a driftwood-covered pocket beach south of Trinidad where a small creek meets the sea. At low tide the rocks reveal tidepools; in calm summer conditions the sheltered corners allow a bracing ocean dip. Surfers work the outside break while swimmers stick to the protected edges.
