Access and trail reports
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.

Reports describe the cited dates. An expected reopening date does not establish reopened access.
This alpine route above Berg Lake crosses shale and rocky ground with views toward the Robson Glacier and Adolphus Lake. A 2025 report describes landslide damage and a signed turnaround; confirm the authorized extent before planning a through hike.
1. Getting there and 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.
- From Highway 16 at Mount Robson, follow Kinney Lake Road to its end and the Berg Lake trailhead.
Parking: The road-access trailhead is at the end of Kinney Lake Road near the Mount Robson Welcome Centre. Upper-corridor camps and viewpoints cannot be reached by car.
2. Walking the route
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.
- The published route links the Robson Pass side with the upper Toboggan Falls area through alpine terrain.
- Before choosing a through-loop, obtain the current authorized turnaround from park staff. The July 2025 account describes a partial landslide closure and did not complete the crossing.
The return
If the connecting section remains closed, return along the permitted approach rather than using a published loop distance to justify crossing the closure. The reviewed report does not verify a complete currently open loop.

5. Camping, facilities and seasons
Camping and tenting
Overnight stays on the Berg Lake corridor must use designated campground sites. Peak-season reservations are required, and campfires are prohibited year-round. Dogs are allowed only on leashed day trips, never on an overnight trip; Snowbird Pass excludes dogs entirely.
Water
The Berg Lake corridor has a permanent water-treatment advisory. Treat water before drinking, cooking or other use.
Season and access
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.
Winter route
BC Parks allows winter use, but warns of severe winter conditions. Use designated camping areas and check current advisories and avalanche conditions; the summer itinerary is not a validated winter track.
Mobile service
BC Parks reports no mobile-phone service on the trail. Service and Wi-Fi are available at the Welcome Centre.
Practical details checked 2026-10-17.
Reservations and current availability
Check the operator’s current rules, opening dates and booking requirements for your chosen campsite or cabin.
