Moul Falls is a waterfall on Grouse Creek in Wells Gray Provincial Park, east-central British Columbia, Canada. It is one of the park's most popular short hiking trails. It is the only waterfall in the park that one can stand behind. Moul Falls is the third highest waterfall in the park, measured as a straight, unbroken drop. Grouse Creek rises from snowmelt, a lake and springs at a pass between Trophy Mountain and Table Mountain. It flows 18 km (11.2 mi) west before tumbling over Moul Falls, then McDiarmid Falls, and entering the Clearwater River.
