The Whistlers is a very busy mountain. You could either hike up 9.6km to the summit for a few hours, or spend $21 and take the Jasper Tramway for 7 minutes, then hike the remaining 1km to the top.
Most parties stay around the station and already be merry. Why not, the view is already breathtaking up there. Push yourself a bit more and you'll receive an even better reward. At the summit, we had a chance to see the highest point of the Canadian Rockies, Mt. Robson.
