If you haven't seen this video yet, check out Alex Matthews and friends sea kayaking and playing at Surge Narrows off Quadra Island, British Columbia. The Surge Narrows are fast-flowing tidal rapids caused by the convergence of two flood tides. Extreme currents can roar through at 16 knots and up to 14 knots on the ebb tide, making Surge Narrows one of the fastest-flowing and most dangerous tidal streams in the world. Best left to the most experienced of kayakers only, the Surge Narrows area is also used for kayak training in the unusual and challenging tidal conditions that prevail. The Discovery Islands Lodge is a 20 minute paddle from Surge Narrows. (For these and other details on the Surge Narrows, see the British Columbia Parks (http://www.env.gov.bc.ca/bcparks/explore/parkpgs/surge_nr/) and Vancouver Island (http://www.vancouverisland.com/parks/?id=534) websites).
