You do not need access to the full mountain on NTSC Day trips. You will stay in the learning area zones.
Both Mount St. Louis Moonstone and Blue Mountain have beginner lift ticket that gives you access to beginner lift only. Please purchase the beginner lift ticket and rental equipment only from the local resort.
When registering with NTSC for a Day Trip, please select "Bus Only" and pay this portion only when you register online.
Once you talk to your instructor, they can advise you then to purchase a full lift pass for you to access Blue Terrain.
