A forest walk builds to a 73 m suspension bridge.
Overview
Black Shale Suspension Bridge Trail is an out-and-back from Black Prince Day Use on the High Rockies Trail, through rolling forest to a 73 m suspension bridge over Blackshale Creek. Use 6.8 km (4.2 mi) round trip as your planning distance and allow about 1.5 to 2 hours. Other published estimates for this approach run from about 6.0 to 7.1 km, so give yourself room for the longer walk. The trail is easy underfoot, but it is a proper outing before you reach the bridge. Choose it for the forest walk and the crossing together, not for a quick photo stop.

Trail guide
From the day-use parking area, walk back to Smith-Dorrien Trail (AB-742) and cross carefully. Look for the signed High Rockies connector on the other side; it climbs through the trees for roughly 400 m before joining the main route. At the junction, turn toward the bridge. That highway crossing is the part to take seriously: traffic moves quickly on this road, and the connector is easy to miss if you are expecting the bridge to sit right beside the parking area.
The High Rockies Trail is a broad, smooth path shared with mountain bikers. It winds through evergreen forest with short rises and dips rather than one long climb. A couple of openings let you look out toward the surrounding mountains, but much of the walk stays under trees. Leave space for riders and keep following the signed route to Blackshale Creek; the return uses the same corridor.
The 73 m rope bridge crosses the steep creek cut directly instead of sending trail users around it. The span sits in a forest clearing, with the tree-covered ravine dropping away below and mountain views beyond. It feels more like a close-up creek crossing than a sweeping alpine lookout. For a photo, step back on the approach and include the curved deck against the forest; from the span, the cables and treetops make the view.
Use Black Prince Day Use Area, where there are picnic tables and vault toilets. There is no drinking water on the trail, and a Kananaskis Conservation Pass is required to park. Dogs are allowed on leash. The bridge itself closes in winter, though a bypass keeps the High Rockies route open; you can still walk through, but you cannot cross the span then. If you only want the bridge, a separate roadside approach is roughly 1 km round trip, but it is a much shorter, less clearly marked access and is not the route described here.
