Powerful Panther Falls is accessible via a short, uphill trail from the Icefields Parkway. The total distance is 900m with 60m elevation gain (allow 20-25 minutes).
If desired, you can continue along the trail to another waterfall, Bridal Veil Falls. The path is narrower and a bit steep in places. It can also be muddy, depending on the time of year and recent weather.
A Parks Canada parks pass is required to drive the Icefields Parkway ($22/day for a vehicle of up to 7 people).
