Underwater Phantaseas

Since 1990, Underwater Phantaseas has been a fixture of the Denver-area diving scene, offering education, travel, equipment sales and gear service to local divers. As a PADI 5 Star IDC with 39 PADI Instructors on the team, it covers every level of PADI training, with lessons run at the centre's own onsite classroom and pool.

Courses and what it's known for

Training runs the full range of PADI levels, alongside PADI Snorkelling and PADI First Aid (EFR). The onsite pool and classroom, air conditioning and retail shop make it an easy place to learn close to home, and a staff who clearly love sharing their knowledge make it welcoming for newcomers and returning divers alike.

Beyond the classroom, the centre handles air fills, equipment sales and a wide rental selection — including kids' equipment and travel gear. Escorted group trips take divers further afield, and the team speaks both English and Spanish. It suits anyone in the Denver area looking to start, continue, or gear up for their diving.
