From the upper Berg Lake camps, climb to views of Hargreaves Lake and its glacier, then combine the visit with Toboggan Falls and a lakeshore return. The long approach to the camps is additional to this side hike.

This roughly 3.2 km return starts at Marmot campground. It differs from the combined 6 km Hargreaves–Toboggan circuit and excludes the long Berg Lake approach. Use current BC Parks access and dog rules.

Mapped named trail. The upper Hargreaves route is shown; approach travel on the Berg Lake trail is not included. Line source (opens original source).
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.
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.
Map position: 53.15250, -119.18417 · named lake reference point (not a trailhead). BC Gazetteer: Hargreaves Lake | Lake | 53 09 08 N | 119 11 03 W | WGS84 | mapsheet 83E/3 Official named-feature location, not parking or a verified route start. This point supports regional orientation and area forecasts; road directions and distance-to-trailhead must use a separately verified access point.
Begin the day outing from Berg Lake campground beside Toboggan Creek, or join at the Hargreaves junction near Marmot campground. Reaching either start first requires the separate Berg Lake approach.
Follow the signed connection between Toboggan Falls and the Hargreaves Lake lookout. Choose the destination at upper junctions rather than taking a Mumm Basin branch without checking its status.
Complete the circuit using the lakeshore trail between Marmot and Berg Lake campgrounds. A direct return from a single viewpoint is a different outing.
Use the Hargreaves/Toboggan connection above the Berg Lake shore. The published loop can be entered near Marmot campground or from the Toboggan Creek side of Berg Lake campground. Climb toward the Hargreaves Lake lookout for elevated views of the lake, glacier and surrounding peaks, then follow the signed connection toward Toboggan Falls and return to the lakeside trail. The commonly described 6 km loop includes both Hargreaves and Toboggan; a direct out-and-back to one viewpoint is a different outing. Do not add the Mumm Basin connection merely to complete a loop without checking its separate damage and closure information.
The first-hand July 2025 report describes the combined Hargreaves/Toboggan circuit as 6 km with about 340 m gain and 2–4 hours from Berg Lake campground. The separate AllTrails approach from Marmot is not this complete combined loop.
The lookout route rises above the lakeshore into exposed terrain. Snow can cover junctions and wet rock can make the steeper sections slippery. Check both the main corridor and individual side-trail advisories before leaving camp.
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.
Source checked October 17, 2026 · BC Parks (opens original source)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.
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. This is a day excursion from the upper campgrounds; no designated camp was verified at the Hargreaves viewpoint.
