Domes Beach
Rincón is where surfing in Puerto Rico is centred, and Domes - named for the decommissioned nuclear reactor dome beside it - is its most recognisable break. In winter it produces serious waves for experienced surfers and is not a place for children in the water. In summer the swell drops right down and the same beach becomes a reasonable place to take a first lesson, with several schools operating locally. The other winter draw is watching rather than swimming: humpback whales pass close to this coast between January and March, and the lighthouse park above the beach is a good vantage point.
