Highest accessible waterfall in Manitoba. At Pisew Falls, the Grass River drops 13 m/ 42.7 ft., changes direction and jets down through a gorge. A short boardwalk leads to observation platforms. Another .5 km/.3 mi. trail leads to the Rotary Bridge over the Grass River below the falls giving access to trails leading to the top of Pisew Falls and to a 22 km return hiking trail to Kwasitchewan Falls, Manitoba’s highest waterfall.
