Polar Prep® Series

Gozo, the quieter sister of Malta, rises from the Mediterranean as a rugged limestone island shaped by wind and sea: dramatic cliffs, natural arches, and stone villages overlooking a deeply carved shoreline. One of Europe’s most distinctive and diver-focused destinations.

• Cavernous underwater rock formations
• Wrecks
• Dive the Inland Sea
• Shore diving amidst dramatic coastlines

Tulum sits along Mexico’s Caribbean coast, where dense jungle meets bright white sand and turquoise water. Just inland, the limestone terrain gives way to hidden freshwater cenotes, an ideal training ground scattered through the jungle.

• Cenotes and cavern systems
• Calm, crystal-clear freshwater with near glass-like visibility
• Warm water, perfect for first-time drysuit divers

Iceland is where the earth splits open. Here the Polar Prep® Series dives glacial meltwater flowing between two continents and lakes fed by volcanic vents. Stark, geologically defined underwater landscapes found almost nowhere else. From the tectonic fissures of Þingvellir to the volcanic depths of the Reykjanes Peninsula, this is true cold-water diving, with North Atlantic ocean sites beyond.

• Silfra and Davíðsgjá fissures in Þingvellir National Park, diving between the tectonic plates
• Up to 300 ft / 100 m visibility in glacial freshwater
• Lake Kleifarvatn on the Reykjanes Peninsula, a volcanic lake with geothermal vents rising through the water
• Cold North Atlantic ocean sites

Duluth is the gateway to Lake Superior’s North Shore, the largest freshwater lake in the world by surface area, holding ten percent of the earth’s surface fresh water in its deep, cold basin along the U.S.–Canada border. Temperate and cold freshwater diving defined by exceptional visibility, preserved historic shipwrecks, and dramatic volcanic geology.

• Fresh water diving
• Preserved shipwrecks and artifacts from bygone eras
• Dramatic volcanic geology and rocky underwater landscapes
