Download-My-AppsWithout a car they are all a bit of a journey from UBC.
Grouse is probably the easiest to get by transit from campus, Seymour is comparable by car. Both have good parks, but Seymour doesn't have a snow making system, so it might be a bit of a gamble this coming season.
Cypress is the largest of the local mountains, but the park is meh, and its fairly far/ expensive.
The locals are fun on the evenings, but on your days off you might as well just head to whistler.
To echo what D-M-A said, Cypress is a journey without a car and Grouse is the only one accessible via public transit. If you have the means and the ride, Whistler is unmatched. And if riding deep and not waiting in lift-lines is your thing, Mt. Baker has never served me wrong.
Regarding the local mountains, I have been riding Grouse for the past 5 seasons and have no complaints about riding there on the weekends/evenings. However, you'll want to avoid it like the plague on weekends. Grouse and Cypress are laughably competitive with each other. They love to one up each other from snow making, open runs, or even operating 1 hour earlier on opening day.
IMO, the terrain is better at Cypress but Grouse consistently has a much better park. The jump line there is the biggest in town (when there is snow) and management does not seem to veto larger features the same way that Cypress does. It'll be good to keep in mind that Cypress' park crew is in shambles after last season and a lot of people seem to have made the switch to Grouse.
I haven't rode Seymour as much... but the natural features are sick (as seen in this TC episode: https://youtu.be/8clsnuOaDPQ?t=5m35s
) and the pass is the cheapest in town. However, I'd put the park in 3/3 though.
The crew and I usually ride week day evenings after work if you are looking for people to hit Grouse with. Also, check out the UBC Freeride
dudes. Those boys are top notch!
