Travel Tips

Parks Pass Required
A Parks Canada discovery pass or day permit is required to stop anywhere in Banff National Park, including Lake Louise viewpoints. Buy online or at the gate - enforcement is active on busy weekends.
Parking & Shuttles
Lake Louise and Moraine Lake parking fills before mid-morning in summer. Use Parks Canada reservations/shuttles where required; do not park illegally on the verge - tickets and towing are common.
Wildlife Distance
Stay at least 100 m from bears and 30 m from elk. Carry bear spray on trails, know how to use it, and never feed animals. Traffic jams around roadside wildlife are dangerous - pull fully off the road or drive on.
Mountain Weather Swings
Snow is possible on high trails even in July. Pack layers, rain shell, and sun protection for the same hike. Check trail reports for closures after storms or for wildlife management.
