CANYON GRADING

Canyon grading is more challenging that Walk grading. It is influenced by access (distance to the canyon, the type of terrain and elevation, navigation difficulty), duration (distance covered, number of abseils), technical difficulty (set ups, exposure, sharp edges, overhangs, slippery surfaces), hydrology (amount and strength of water flow, water temperature), volatility (how prone to change due to weather conditions). Some grading systems provide separate scores for these factors, others try to combine them into one measure.

We follow a simple system, using the same grades as the walk grading system. But bear in mind that canyoning is bushwalking on steroids so the grades are not equivalent! An Easy canyon is like a Medium-Hard bushwalk - off track and with slippery, uneven surfaces. So I grade canyons starting at Medium and progress to Very Hard.

Grade 3 (Medium): Even a beginner canyon like Wollangambe 1, with no abseiling, is a commitment of some 6-8 hrs. Constant immersion in cool water can sap your strength, even with a wetsuit. Some agility and a sense of adventure is required.

Grade 4 (Medium-Hard): These canyons are either longer or cover greater elevation (a harder walk out) or may have more technical abseils. Suitable for people with some abseil canyoning experience and some walking fitness.

Grade 5 (Hard): These canyons have 2 of 3 additional difficulty factors (greater distance, more elevation, more technical abseils) and are not suitable for beginners.

Grade 6 (Very Hard): Grade 6 canyons require considerable commitment (perhaps 9-10 hrs on the track) and previous abseil canyoning experience. Definitely not for beginners.
