The Mumm Basin route climbs above the upper Berg Lake corridor and connects the Robson Pass side with the Toboggan Falls area. The terrain includes open alpine ground, shale and rock, with broad views of Berg Lake, Robson Glacier and Adolphus Lake. A 2025 trip report describes lingering landslide damage and a signed turnaround on the Robson Pass side; that report’s authors did not complete the route. Do not treat a published loop distance or another visitor’s passage as confirmation that the damaged connection is open. Ask park staff which section is currently authorized and plan an out-and-back to the signed turnaround if the through-connection remains closed.

Getting there & parking
From Highway 16, turn into the signed Mount Robson park entrance near the Welcome Centre and follow Kinney Lake Road about 2.3 km to the road-end Berg Lake Trail parking. This is the vehicle access for the whole Berg Lake corridor. The waterfall and upper-basin destinations have no separate road approach. First hike the main corridor to a reserved upper campground near Berg Lake. The side-trip distances on this record begin in that upper area and exclude the much longer approach from the road.
Driving access has not been established for this selected route option; check its original sources.

Conditions & seasons
The route is exposed to mountain storms, lingering snow and rockfall terrain. Its landslide restriction is separate from the reopening of the main Berg Lake Trail. Check the individual route status before attempting any loop.
Robson watercraft and wading equipment restriction
From May 4, 2026, BC Parks prohibits watercraft and wading equipment throughout Mount Robson Park waters to limit aquatic disease spread. This includes powered and unpowered craft, inflatables, wading clothing and boots. The hiking trails are not closed by this notice.
These are dated research notes. Open the trip planner for current available weather and advisory feeds; no alert found does not establish that a trail or road is open.
Overnight stays belong in designated Berg Lake Trail campgrounds, on tent pads or other established sites. Reserve the selected campground during the peak booking season; a day-hike visit does not provide a camping reservation. The corridor has a permanent campfire ban, and water must be treated. Dogs are not allowed on overnight trips. The basin is an upper-campground day hike; the reviewed sources do not identify a designated tent site along its exposed traverse.
