Escambrón is a shallow shore dive in a protected urban bay near Old San Juan with sandy and rocky sections, artificial reef structures, and easy beach access. It is commonly used for check-out dives, training, snorkel sessions, and relaxed scuba outings, with city convenience making it a simple half-day dive rather than a remote boat trip. Plan for calmer mornings when possible, since wind and park traffic can change the feel of the site.
