I'm interested in doing a 6-day hike in Mt. Robson Provincial Park in late-August. The Berg Lake Trail sounds amazing, but it seems like only a 4-5 day adventure.
Day 1: Trailhead to Berg Lake (21km)
Day 2: Dayhike Hargreaves Glacier / Toboggan Falls / Mumm Basin Loop (12km)
Day 3: Dayhike to Snowbird Pass (21.2km)
Day 4: Berg Lake back to trailhead (21km)
Any suggestions for how to fill 2 more days? I would prefer not to leave the trail at all during this 6 day stretch. I know Day 2, at Robson Pass, brings me to the border with Jasper National Park. Is it worth hiking over the Pass and spending 2 days in Jasper, before returning to finish the last 2 days seeing Snowbird Pass and hiking back to the trailhead? And if so, what are the highlights reachable by foot in that part of Jasper?
