The hike starts at Takakkaw Falls parking and continues through the Yoho Valley trail system. Parks Canada's route description places Laughing Falls about 4.5 km in, then Twin Falls another 3.9 km beyond; allow around six hours of walking round trip, plus time at the falls and the historic site. The Takakkaw lot can fill early on summer days and weekends, so have a backup plan.
Yoho Valley Road is seasonal, generally open from mid-June to mid-October. Its steep switchbacks aren't suitable for RVs or trailers, and vehicles longer than about 7 m may need to reverse around tight corners.
