Descent starts just off the corridor route footpath with a series of uncomfortable slides, or bypass these to arrive at the first fall. Further down climbs lead to the start of a very steep section with a long series of abseils. Exits from the canyon are available often and the trip is easily combined with Corridor Canyon - easiest to do Greta Canyon first and exit one fall above the confluence onto and then ascend the narrow grassy ridge on the right separating the two streams.
