BC Parks uses parking capacity as a factor to determine how many day passes to allow. See my earlier post on the topic of Carrying Capacity that explains it. I did some quantitative analysis to see how germane parking capacity is to the carrying capacity.

I only looked at the South Coast region excluding Golden Ears because it uses vehicle passes. Cypress, Seymour and Stawamus Chief have virtually unlimited parking options. Rubble Creek has massive capacity because parking is possible along the 2 km park road. Diamond Head and Cheakamus trailheads probably each have between 50 to 100 parking spots, more so at Diamond Head.

Cheakamus parking lot is outside the park. So, it may not even be legal for BC Parks to restrict parking and check for passes until past the park boundary about 600 meters in from the parking lot.

Cypress and Seymour have huge parking lots for downhill skiers. Stawamus Chief has huge amounts of available parking outside the park along Mamquam FSR and at Darrell Bay.
