Seymour Narrows Tour
Experience Seymour Narrows' world-famous tidal currents with our Campbell River, BC boat tour. Navigate one of Vancouver Island's most powerful natural passages, witness the historic Ripple Rock explosion site, and explore where currents reach 16 knots through Discovery Passage.
Why is Seymour Narrows famous?
Located between Campbell River and Quadra Island, Seymour Narrows is one of the world's most famous tidal passages, with currents reaching up to 16 knots. In 1958, the underwater Ripple Rock was destroyed in the largest non-nuclear explosion ever detonated, making the passage safer for ships navigating this critical BC waterway.
Our experienced Campbell River captain will navigate you safely through this incredible natural phenomenon while sharing the fascinating history of this important waterway. Watch for bald eagles, harbour seals, and other Vancouver Island wildlife drawn to the nutrient-rich waters of Discovery Passage.

The Ripple Rock Explosion
On April 5, 1958, Canada executed the world's largest non-nuclear planned explosion in Seymour Narrows, just north of Campbell River. The target: Ripple Rock, a deadly twin-peaked underwater mountain that had claimed 114 ships and 114 lives since the 1800s.
Engineers tunneled 570 feet down through Maud Island and then 2,400 feet under the seabed to reach the twin peaks. They packed 1,375 tonnes of Nitramex 2H explosives into chambers carved beneath each peak.
At 9:31 AM, the detonation launched 635,000 tonnes of rock and water over 300 metres into the air. The blast was broadcast live on CBC television, one of Canada's first coast-to-coast live broadcasts.

Why It Matters to Fishermen
Today, Seymour Narrows is safe for navigation but the powerful tidal currents remain, funneling massive schools of salmon through this narrow passage. The explosion lowered the rock's peaks from 9 feet below the surface to a safe 45 feet, opening one of BC's most productive fishing corridors. This is now one of our prime fishing spots, best fished at slack tide when the currents ease.
