Lower Mainland, BC
Just north of the Vancouver international airport (YVR) is a pipe leading four kilometers into the strait . It's covered over and you can walk or bike ride out to it's end on this covering, shown here. Halfway to the end is this shelter set up for sudden storms so trekers won't get washed away. FYI: this picture is reversed to provide better centering.
On the Fort to Fort Trail
The Fort to Fort Trail in Langley, BC is an excellent walking/biking/jogging trail that extends from Derby Reach to Fort Langley. It meanders along the Fraser River. In this photo Golden Ears mountain is in the distance.
