For a less-crowded experience, ask your dive operator about exploring the smaller, unnamed patch reefs between the main islands.

Exploring these lesser-known spots provides a more intimate look at the park's biodiversity.

Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Rosario Islands, Colombia?

However, there are subtle seasonal events. For instance, you might observe coral spawning events around August and September, typically after a full moon. Turtle nesting season on nearby beaches also occurs between May and November, increasing the chances of seeing green or hawksbill turtles in the water during that time.

While larger encounters are less common, hawksbill and green turtles are frequently spotted, along with southern stingrays gliding over the sandy bottoms. The area is also great for spotting smaller critters like arrow crabs and nudibranchs.
What thickness wetsuit should I wear in Rosario Islands, Colombia?
Given the warm, tropical waters of the Rosario Islands, Colombia, minimal thermal protection is needed. A 3mm shorty or full wetsuit is sufficient for most divers year-round to provide comfort during longer dives and protection from the sun and coral. Some divers may even be comfortable in just a rash guard and swim shorts, especially during the warmest months (June-October). If you tend to get cold easily, a 3mm full suit is a safe and versatile choice for any season.

Most dive centers are based in Cartagena and organize daily trips that include transportation to the dive sites. Alternatively, you can take a public lancha (speedboat) from the La Bodeguita pier or arrange a private charter if you are staying on one of the islands.
Should I book a liveaboard or stay on shore in Rosario Islands, Colombia?
