The falls sit at kilometre 23 on West Coast Trail markers from Pachena Bay. From Nitinaht Narrows, the route itinerary makes the falls an 8 km first-day destination. Everyone entering the West Coast Trail, including day hikers, needs a backcountry permit and must complete the orientation and check-in. Expect a remote, rugged route with mud, river crossings and many ladders; plan the full approach and exit, not just the last stretch to the beach.
The trail closes each year from October 7 through April 30. The limited winter day-use exception covers only the first 8 km from Pachena Bay, so it does not reach Tsusiat Falls. Check current trail access and transport arrangements before planning your trip.
