Burstarse Falls is accessed from the PCT, there is a wooden sign in a tree that reads Burstarse Creek. There is a lower falls and upper falls. The upper falls is at least two or three times taller, but more difficult to access. Stay on the east side of the creek as you pass the lower falls. Eventually you will find an area to cross to the west side when the canyon wall makes progressing on the east side not possible. Continue up the canyon, and you'll eventually be able to cross back to the east side for a spectacular view of the large upper falls.
