Porteau Cove
Porteau Cove is another one of the best dives within a half hour of Vancouver, and is another one of the popular British Columbia artificial reefs.
Weekends can be busy since this dive site is a popular spot for all the local scuba dive training and dive lessons. Visibility can also be an issue, so check ahead with a local Vancouver dive shop to see what conditions have been like. Many visitors like to book an escorted scuba safari with our preferred Vancouver dive instructor/divemaster.
Directions To Porteau Cove
The beginning directions to this dive site are the same as to Whytecliff Marine Park. Follow the signs over the Lions Gate Bridge and take the Upper Levels Highway west towards Horseshoe Bay and Highway 99 to Whistler, but instead of taking the exit to Marine Drive, take the Squamish / Whistler exit. About 23 km later (15 miles) you will turn left off the highway and into Porteau Cove Provincial Park.
It is a beautiful, scenic drive through Howe Sound, past the Fury Creek Golf Course and past the historic mining site and Mining Museum at Brittania Beach. Be careful though, because this highway is the busy route to Whistler and because there are some impatient drivers who like to speed excessively on this windy highway. The police are typically watching for speeders along the Sea-to-Sky highway so Drive Safe to Dive Safe!
What's At Porteau Cove?
Some divers call Porteau Cove a Diver’s Playground and some call it a Diver’s Paradise, and when you dive this area of artificial reefs you will see why. As you turn into the Provincial Park, you will pass information signs and maps that show the location of several wrecks. Plenty of marine life is attracted to these wrecks, including giant ling cod and colorful plumose anemones making your dives even more exciting.

A jungle gym type of artificial reef network has been constructed from groups of tires, concrete piles & blocks, and steel beams, which are full of rock and ling cod, star fish, nudibranch, and even an octopus or two.
One of two yellow markers indicates the location of the Granthall, a 28 meter steel-hulled CPR tugboat built in Montreal in 1928. In 1967 the superstructure was removed and the Granthall became a herring packer, which was then scuttled to serve as an artificial reef in 1992. The second yellow marker at Porteau Cove shows the location of a 30 foot (11 meter) rusty crane barge named the Centennial III, which also lies near a 40 foot (15 meter) cement sailboat hull. You should see orange and white plumose anemone, shrimp, grunt sculpins, kelp greenlings, crabs, sea cucumbers, ling cod, perch, and other rock fish.
For more advanced scuba divers, at a depth of around 90 feet (33 meters), lies the remnants of a former minesweeper called the Nakaya, which was scuttled in 1985 at the northern edge of the diving area. The surface marker has been removed, so from the last white buoy, take a heading of about 30 degrees. You should find the old Nakaya anchor line, which still has a round buoy 10 feet under the surface holding most of the line up.
From there go left (out/deeper) and you should run right into wreck of the the Nakaya. This wreck is in very rough shape and penetration is no longer permitted. The bouy may even be missing now due to the dangers
