Turtles in the City: Snorkeling San Juan’s Escambrón Marine Park
Calm, clear water, sea turtles on the seagrass, and a reef just minutes from Old San Juan.
The sea is already awake when you wade in—clear as polished glass, with the Atlantic rolling a soft shoulder against the reef. Palm fronds gesture in the trade winds. Waves murmur at the edge of Old San Juan’s skyline, and the current gives you a small nudge, as if to say: follow me. You float face-down and the city slips away. Below, a meadow of seagrass sways like a living tide, and a green sea turtle glides into view, unhurried, as if it owns the morning. It does.
Trail Wisdom
Go Early for Glassy Water
Morning sessions often mean lighter winds and better visibility before the trade winds pick up.
Rash Guard Beats Sunscreen
Wear a long-sleeve UPF top to cut down on sunscreen use and protect the reef; choose mineral, reef-safe formula if you apply.
Fin Technique Matters
Slow, straight-leg kicks keep you streamlined and reduce silt; avoid bicycle-kicking, which stirs up the bottom and spooks wildlife.
Give Turtles Space
Stay at least 10 feet away and never chase or block their surfacing path; let them set the terms of the encounter.

Yes, if they’re comfortable swimmers and accompanied by a parent or guardian. Ask about minimum age and sizing for gear.
