Tolú is the lively sister town to Coveñas on the Gulf of Morrosquillo, a warm, sheltered bay in the department of Sucre that fills with Colombian holidaymakers. It is best known as the jumping-off point for the Islas de San Bernardo, a cluster of small coral islands reached by boat from the Tolú waterfront. The gulf itself is shallow and often murky near shore, so the good snorkeling and diving is out among the islands and offshore reefs. And just south of the gulf lies Isla Fuerte, one of the finest dive destinations on this part of the coast.
Tolú and the San Bernardo islands
From Tolú, boat tours run out to the San Bernardo archipelago, including Isla Múcura, Isla Tintipán and the famously crowded Santa Cruz del Islote, said to be one of the most densely populated islands on Earth. These islands offer snorkeling over shallow coral, mangroves and warm lagoons.
The reefs around San Bernardo have suffered from heavy tourism and fishing over the years, so their coral health is patchy, but the islands remain a beautiful and popular day-trip destination.
What the gulf offers and what it lacks
The Gulf of Morrosquillo is a wonderful place for a relaxed beach holiday: calm water, seafood, sunsets and easy boat access to the islands. It is family-friendly and affordable, which is why Tolú stays busy in every high season.
What it lacks is consistently clear, healthy reef right at your doorstep. For that, divers look to offshore islands where the water runs cleaner and the coral is better preserved.
From Tolú down to Isla Fuerte
Isla Fuerte sits 11 km off the coast of Córdoba, just south of the Gulf of Morrosquillo. From Tolú, the drive to Paso Nuevo, where the island boat leaves, takes roughly 2 to 3 hours. That short journey opens up a completely different quality of diving.
Where the San Bernardo reefs feel busy and worn, Isla Fuerte's 29 dive sites include gentle beginner reefs, a submerged Zenú museum and deep advanced walls, all in warm, clear, well protected water.
