Entrance to Ambleside Park is by 13th and Marine in West Vancouver. Take the 15th street exit off the highway. When the current is ebbing with NW wind and wave action, the waves stand up where they collide with the strongest current. Same as the Gorge. From shore you can see the tide rip. It's like a strip of rough water. Its always different, but usually 500 - 1000 yards offshore. The water in between shore and the tide rip is usually calm or rolling. Lots of easy water to play around in. Waves are rolling upstream against the current, like the Gorge. So you paddle out to the rip and bite off as much as you can chew. Surf upstream, float back downstream for another run. See map below.
