Cartagena: 4 Rosario Islands Snorkeling & Bioluminescent Plankton
Cartagena: 4 Rosario Islands Snorkeling & Bioluminescent Plankton★★★★★★★★★★ 3.38 (13)12hYou're picked up from your Cartagena hotel and taken by boat to four islands in the Rosario archipelago, where you snorkel in clear water, eat lunch and fresh fruit on the islands, and finish the day swimming in bioluminescent plankton after dark. Snorkeling gear, meals, and all transport are included; you just show up and follow the guide's timing.Is it for me?Book this if you want the main Rosario Islands experience—snorkeling, island stops, and meals—without arranging your own boat or timing, and you're willing to stay out until evening for the plankton swim, which is what makes the full day possible.Free cancellationfromUS$ 70View ›

The fixed 9am start and 4pm return fit a single day without eating into your evening, and the guide in English or Spanish means you follow what's happening at each stop.Free cancellationfromUS$ 105View ›
Snorkeling Rosario Islands: 5 islands with plankton
Snorkeling Rosario Islands: 5 islands with plankton★★★★★★★★★★ 4.25 (4)8hA full-day snorkeling tour of the Rosario Islands with a live guide in English or Spanish, departing from Cartagena with hotel pickup included. You snorkel at a coral pool and a sunken plane site, visit five islands with stops for lunch and a shrimp cocktail, and finish with a plankton swim at sunset. The tour runs eight hours and includes snorkeling equipment, bottled water, an air-conditioned boat and restroom access; entrance to the oceanarium is separate.Is it for me?Book the version with plankton if the bioluminescent swim is your main draw; without it, you get the same snorkeling and island stops but skip the night water activity.Free cancellationfromUS$ 130View ›
Rosario Islands Day Trip: Snorkel & Lunch at Isla del Sol
Rosario Islands Day Trip: Snorkel & Lunch at Isla del Sol★★★★★★★★★★ 3.55 (98)8hA full-day trip from Cartagena to Isla del Sol in the Rosario Islands combines speedboat transport, snorkeling in protected waters, and a lunch of fresh-caught fish on the beach. Hotel pickup covers central neighborhoods (Boca Grande, Laguito, Casco Antiguo, Getsemani), and the boat departs between 9:00 and 9:30 AM depending on traffic. Basic driver support is available in English and Spanish, but this is not a guided tour — you set your own pace on the island. The Rosario Islands are a national park established in 1977, home to coral reefs and tropical fish. A port fee of 18,500 COP (payable in cash before boarding) is separate from the tour price.Is it for me?The boat ride is fast and the island time is unstructured, so this suits a traveler who wants a beach and water day without a schedule or a guide talking — you arrive, swim or rest as you choose, eat lunch, and leave when the boat does. The early departure (between 9:00 and 9:30 AM) and eight-hour commitment work best if you have a full day free and don't mind an early start from your hotel.Free cancellationfromUS$ 238View ›
