Tortuga Bay, Greeley

The certified staff at Tortuga Bay lives and breathes all things scuba, offering everything from training and equipment to planned trips to exotic underwater destinations. The shop's greatest claim to fame is a state-of-the-art indoor, heated saltwater pool the website claims is the deepest in captivity.

Owner Ron Bland and his team of experienced instructors introduce beginners to diving with a three-step certification system that begins with online or classroom academic training and progresses to pool lessons and open-water evaluations. The scuba center also offers advanced courses and excursions for more experienced divers.
