Driving to Blue Mountain!
(It's easier than it seems!)
The Blue Mountain Village is located at: 156 Jozo Weider Blvd, The Blue Mountains, ON L9Y 3Z2
If you're the brave sort that drives without the help of GPS or Google Maps, Blue Mountain has some excellent directions on their website here.
YetiCon indoor activities are held in the Blue Mountain Village Conference Centre. The Village Conference Centre is completely wheelchair accessible!
Currently there are no plans for Summerbound or any other bus company to run public transportation directly to Blue Mountain Resort for YetiCon 2018. However, Greyhound does have transportation from Toronto to Collingwood (the town Blue Mountain directly borders) where you can take a short trip via taxi/uber to the resort.
Additionally, Summerbound transportation can be chartered from the GTA directly to Blue Mountain. However, it can be costly if you do not have a group to split it with.
If those options are unappealing, and you are still unable to catch a ride, you may want to look into carpooling or ride-sharing to get directly to the resort.
