Cayo Acuario

Cayo Acuario is a small, uninhabited cay with no hotels or major infrastructure, but it does have a few local vendors selling seafood and drinks. Visitors usually spend a few hours swimming, snorkeling, and enjoying the shallow waters before returning to San Andrés. The cay is part of the Seaflower Biosphere Reserve, which means its ecosystem is protected, and visitors are encouraged to be eco-friendly. The water depth varies from knee-deep to waist-high, making it a great spot for all ages. Since the area gets plenty of sun year-round, bringing sunscreen, sunglasses, and a hat is essential.

Before visiting Cayo Acuario, it’s important to be prepared for a natural and eco-friendly experience. This small, protected islet has no large facilities, only a few food stalls offering fresh seafood and drinks. The shallow, crystal-clear waters are perfect for snorkeling, with plenty of tropical fish and stingrays visible beneath the surface. Since some areas have rocks and coral, water shoes are recommended for comfort. Payments on the cay are cash-only, and there is a small entrance fee to support conservation efforts. The weather can impact conditions, so checking forecasts before your trip is advised, especially since windy days can cause rougher seas. There is very little shade, so bringing sunscreen, a hat, and sunglasses is essential. For a more peaceful experience, it’s best to arrive early in the morning before the crowds.

The only way to reach Cayo Acuario is by boat from San Andrés Island, with the journey taking around 10 to 15 minutes. Boats leave from Spratt Bight Beach and other main docks throughout the day, usually as part of organized tours or round-trip transfers. Tickets can be booked at local tour offices or directly at the docks. The boat ride is generally smooth, but it’s always a good idea to check weather conditions, as rough seas can make the trip less comfortable. Since Cayo Acuario is a popular destination, boats depart frequently, especially in the morning.
