The usual route follows the former Carbon River Road from its entrance to Ipsut Creek Campground, then takes a short spur to the falls. Plan on about 11 miles round trip with modest climbing; most of the way is a broad, gently uphill roadbed. The road was closed to vehicles after flood damage in 2006, so you cannot drive to the falls. Check current park access before setting out: this route depends on bridges and flood-prone trails.
Parking and restrooms are listed at the Carbon River entrance area, not up at the falls. There is no food service or drinking water listed for the falls or campground, so bring what you need for the long outing.
