Serious SUPers, this one’s for you. Visit one of the area’s lesser-known cenotes that is perfectly suited for standup paddleboarding. Kaan Luum Laguna is unique in that it is both a lagoon and a cenote: the outer edges have lush vegetation and are relatively shallow, but the center is said to be about 260 feet (80 meters) deep. The sides are muddy and there are no beaches here, so get comfortable on your board and enjoy being on the water. After the tour, enjoy a fresh coconut water before heading back to Tulum.
