Howe Sound

With nearly 16,000 miles of rugged coastline and more than 40,000 islands and islets, British Columbia’s Howe Sound features fantastic marine life and spectacular coldwater scuba adventures. Stretching 27 miles from its narrow head under lofty mountain peaks at Squamish to its wide-mouth opening into the Strait of Georgia just northwest of Vancouver, Howe Sound is North America’s southernmost fjord. This sea-to-sky corridor crafted by glaciers and perfected by time seems tailor-made for subsea exploration — reef and wreck, rec and tech.

Florida Panhandle: Down the Emerald Coast

When I dive in an unfamiliar area, I tell the dive operator I want to start at their best spot — the site with everything. If I get bored with that, maybe I’ll try other sites. If you came to my home turf on the Kona Coast of Hawaiʻi Island and asked me for the site that has everything, I would send you to Ripoff Reef.

Hawaiian spinner dolphins often use the Honōkohau boat channel as a resting and socializing area.

The Great Lakes: Where Giants Sleep 

The inland seas of the five Great Lakes have a long history of tragedy and shipwrecks. Mariners who sail their waters know the dangers of autumn storms. Thousands of shipwrecks litter the bottom here due to errors in judgment, equipment failure, or simply being in the wrong place at the wrong time.

Kentucky Blues

Mammoth Cave National Park and other cave systems are part of a limestone belt that defines Kentucky’s landscape with its gently sloping bluegrass valleys. This geography made way for Kentucky to become the thoroughbred horse capital of the world and drive an economy built around events such as the Kentucky Derby. Beneath this limestone bedrock, a water supply often ranked No. 1 for water quality in the United States fuels well-known and developing dive sites that are surprisingly blue.
