In reply to Glennevans:
As said there is an easy chimney descent at the far end which is a little tight at the top before opening out. There is a bolt for a rope / handline if necessary.

In a dry summer the waterfall dries up and so you can climb up it, using this descent in winter you might get wet but there are bolts off to the side of the main fall.
There are some great photos online with the hole filled to the brim of water!
