The Jasper SkyTram takes you up to the Whistlers Mountain to an elevation of 2,263 metres from where you can take a short 1.5 km hike to the summit. The views of the town of Jasper and surrounding mountains are pretty amazing!
If you're feeling like hiking the whole thing instead, it's possible, but be ready for a 16 km round trip hike with more than 1200 meters of elevation gain (yep, it's a leg killer).
PS: Jasper Skytram only runs seasonally during the summer months.
