Sooke Flow Pipe is a great hike. Not recommend bringing pets or children as the pipe can be slippery.
Easy access from the Sooke Potholes Parking lot #2. The trail starts right behind the red hut.
The hike up to the flowline takes about 10 minutes. Walking right along the line takes about 7 minutes to a very impressive trestle with the flowline on top.
Turning left, you can hike along for a while. You can stop at the potholes on top of the flowline and jump into it. Hear the echoes as well.
