Rosario Islands Sea-Pool Beach Club Day by Speedboat

Here’s the thing about the Rosario Islands: they’re coral islands, so a lot of ‘beaches’ are more rock than sand. Isla del Sol’s answer is a proper sea-water pool — a big, clean saltwater pool right beside the beach — so swimming is easy and the kids are happy. Add a laid-back stretch of sand, sun loungers, and a buffet lunch, and you’ve got a relaxed island day on Isla Grande, inside the Corales del Rosario y San Bernardo National Natural Park, that simply works.

Here’s how the day runs. You meet at Muelle de la Bodeguita in the Old City at 7:45 a.m., board a shared speedboat, and cruise about 45 minutes across the bay past Cartagena’s historic fortresses. At the island you’re welcomed with a cocktail, then the day is yours — swim in the sea-water pool, lounge on the sand, and settle in. Around midday a buffet lunch lands with six options and a typical dessert. Optional extras like snorkeling, kayaking, or a mangrove boat ride are available on the island at extra cost. Around 3:00 p.m. you head back, reaching Cartagena between roughly 4:00 and 5:00 p.m.

Who it’s for: families who want a safe, easy place for kids to swim; couples who want a calm pool-and-beach day rather than a party boat; and anyone who’d rather settle at one relaxed spot than hop between crowded islands. Come for the pool, stay for the quiet.
