Start at the Lake Annette / Paradise Valley trailhead on Moraine Lake Road and follow Paradise Creek through spruce-fir forest, bridges, and small meadows. Lake Annette is a scenic halfway landmark beneath Mount Temple and a sensible turnaround for a shorter outing. Beyond the lake, the trail crosses rougher rock and scree along Mount Temple's slopes before reaching a junction in the upper valley. Take the westbound branch toward the Paradise Valley campground and Giant Steps; the straight-ahead branch continues toward Sentinel Pass and Larch Valley and is not part of this hike.
This is an out-and-back to the base of the Giant Steps waterfall: about 12.6 miles (20.3 km) total, with roughly 595 m (1,950 ft) of cumulative ascent and 255 m (835 ft) of descent in Parks Canada's trail figures. The mapped one-way corridor is about 10.0 km. Plan 7–8 hours including photo stops and time at the falls.
