Fodor's Expert Review Sunwapta Pass

Marking the border between Banff and Jasper national parks, Sunwapta is the second-highest drivable pass—2,034 meters (6,675 feet)—in the national parks. Wildlife is most visible in spring and autumn after a snowfall, when herds of bighorn sheep come to the road to lick up the salt used to melt snow and ice. Be prepared for hairpin turns as you switchback up to the pass summit.
