If you are from Greater Vancouver/planning to visit, it is a great place to spend two or three hours. You drive as if you were going to the airport, but eventually you hit a point where you continue straight to go to the terminal or follow the signs to turn off to go to Templeton St/Iona Beach. Then it's a long-ish road until you reach the park and lots of cars in the (free!) parking areas.
Do you have any cool, not-so-popular places to visit in your city?
