First Waterfall Ravine is a little-used climb up Devils Peak not marked on the new Mountain Club map, but the path has been in existence since the blockhouses were built at around the turn of the 19th Century. It is known as the 1000 Steps, which just about sums it up - quite a climb but with a very rewarding view from the nek at the top of the gorge. The gorge is reached from the Blockhouse above Rhodes Memorial: a path above the Contour Path skirts the mountain and enters the gorge. The ascent then begins in some indigenous forest, although there is a brief section out of the gorge to pass a waterfall. Towards the top the gorge is more open and very loose - tumbling rocks are a real danger and the party should stick close together. There are one or two rocky scrambles and the top section is very sandy and steep.
Once you have admired the view over the city bowl and Table Bay you can descend by Mowbray Ridge or take the frontal ascent to Devils Peak itself - best attempted with someone who knows the route.
Not to be confused with Second Waterfall Ravine, which is impassable and has claimed the lives of many unwary hikers.
