Punta Las Marias is a breezy point at the eastern edge of San Juan, between Ocean Park and Isla Verde, fringed by a rocky reef that draws snorkelers and windsurfers alike. The reef sits close to shore and shelters reef fish, urchins and small coral heads, with clearer water than the beaches closer to the river mouths. It is less developed and quieter than Escambron, which makes it a good second stop for snorkelers who want to escape the crowds, though it is more exposed to wind and best on calm days.
How to snorkel it
Snorkel Punta Las Marias only on calm, low-wind days, as the point is exposed and chop builds quickly in the afternoon trades. Enter from the sheltered pockets of sand between the rocks, wear water shoes for the rocky bottom, and stay inside the reef line. It works best as a quieter add-on to an Escambron morning rather than a beginner's first solo snorkel, since there are no lifeguards.
Hours & practical info
Open beach with free public access during daylight hours. No lifeguards, so check conditions first.
Insider tips
✓ Only snorkel here on calm, low-wind mornings.
✓ Wear water shoes for the rocky entry and bottom.
✓ Treat it as a quieter add-on after Escambron, not a beginner solo spot.
On calm days, yes. A rocky reef close to shore holds reef fish and small coral heads, with quieter water than Escambron, but it is exposed to wind and has no lifeguards.
Is Punta Las Marias suitable for beginners?
Less so than Escambron. There are no lifeguards and the entry is rocky, so beginners are better starting at Escambron and treating Punta Las Marias as a later, calm-day stop.
