The closest airports to Jasper National Park are Edmonton (YEG) and Calgary (YYC). From there, it takes 4 and 6 hours respectively to reach Jasper by car.
To explore any of Canada's 47 National Parks, you will need to buy either a daily park pass or a yearly Discovery Pass. The yearly pass pays for itself in 5-7 days. You can order the National Park Pass online ahead of time, or purchase at the entry booth before you enter the park.
When visiting in the winter, invest in clip-on ice cleats available from any sporting goods store or even online for as little as CAD$15. They easily attach to your own winter boots and help explore icy areas safely.
While the glaciers do look more majestic during winter time, it isn't possible to tour, hike or otherwise explore them until late spring or early summer, depending on weather conditions. Glacier and Icefields tours begin running in May, while guided adventure hikes and even ice cave explorations start in June.
For the best chance to witness the ice bubbles in Abraham Lake, plan your trip during the second half of January. Once at the lake, the best spots to capture the bubbles are rumoured to be Preacher's Point, Belly of Abraham and Hoodoo Creek.
