A sandbank off of San Andrés, Acuario is surrounded by calm water that attracts all manner of fish and marine life. The water is so beautifully clear and shallow that snorkelling equipment is not even strictly necessary, but definitely adds to the experience. Afternoons are the best times to come, for those interested in swimming with manta rays.
El Hoyo Soplador is one of San Andrés’s natural wonders. Located at the southern tip of the island, it’s a small geyser that shoots sea water up into the air—20 metres high at a time—through a natural hole in the coral rock.
