Located just off San Juan’s coast, Candado Cave provides intermediate and advanced adventurers with a thrilling underwater cavern system that reaches depths of 70 feet. The cave’s natural limestone formations create stunning archways and tunnels, making it a prime destination for underwater photography enthusiasts.
Due to its enclosed environment, snorkelers must possess cave diving certification and follow strict safety protocols. The cave features multiple chambers with varying light penetration levels, creating dramatic plays of sunlight through the entrance. Marine life includes lobsters, moray eels, and occasional nurse sharks seeking shelter in the darker recesses.
While visibility typically ranges from 40-60 feet, currents can affect conditions. Expert guides are mandatory, and proper cave diving equipment, including backup lights and guide lines, is crucial for safely traversing this remarkable underwater maze.
Aguadilla’s Black Wall Drop
Along Puerto Rico’s northwestern coast, Aguadilla’s Black Wall Drop descends dramatically from 40 to 130 feet, creating a sheer vertical reef face that attracts both pelagic species and experienced adventurers.
The site’s striking black coral formations and deep blue backdrop provide exceptional underwater photography opportunities, particularly during morning immersions when sunlight penetrates the clear waters. Marine life thrives along the wall, with regular sightings of eagle rays, sea turtles, and schools of jacks patrolling the depths.
Due to occasional strong currents and significant depth, the Black Wall Drop requires advanced certification and proper planning for exploration. Local dive operators recommend using nitrox to extend bottom time. The site’s remote location and challenging conditions reward skilled divers with pristine reef sections and virtually untouched marine ecosystems.
La Corona Reef Platform
The sprawling La Corona Reef Platform stretches across Puerto Rico’s southern coast, offering snorkelers a diverse ecosystem of coral formations at depths ranging from 15 to 60 feet. This extensive reef system showcases remarkable marine biodiversity, hosting elkhorn coral, brain coral, and vibrant sea fans that create an ideal habitat for tropical fish species.
The site’s excellent visibility and moderate currents make it perfect for underwater photography enthusiasts. Scuba divers regularly encounter schools of blue tangs, parrotfish, and occasional reef sharks gliding through the coral corridors. The platform’s varying depths accommodate both novice and experienced scuba divers, though local guides recommend morning excursions when water conditions are typically calmest.

Desecheo Island’s Western Reefs
Moving west from Rincón’s coastal reefs, Desecheo Island stands as Puerto Rico’s premier deep-water destination, located 13 miles offshore from the mainland. The western reefs offer advanced snorkelers exceptional visibility, often exceeding 100 feet, and dramatic wall immersions teeming with diverse marine life.
The island’s protected status as a National Wildlife Refuge has preserved its delicate desecheo ecology, creating an underwater sanctuary where eagle rays, Caribbean reef sharks, and massive schools of chromis thrive. Expert snorkelers can probe depths ranging from 60 to 130 feet, uncovering pristine coral formations and deep caves.
However, strong currents and open ocean conditions demand careful planning and advanced certification. Local snorkeling operators strictly follow reef conservation protocols, limiting group sizes and enforcing no-touch policies to protect this remarkable ecosystem.
