Flagstone Canyon is a fantastic big drop and committing canyon for advanced canyoneers. The canyon features the impressive, multi-terraced Flagstone Falls with approximately 300 metres of elevation drop in 200 metres.
See the 'How to get to Flagstone Falls' article.
The canyon has some large drops and some advanced rigging (knot blocks) required. The rappels are broken up into multi-pitches. It's a good idea to take bolts and a hand drill with you as some of the natural anchors are less than perfect.
~15m into pool from tree - can stop on the lower ledge and then jump in.
It may be possible to rappel in waterfall from chockstone.
High flow hazard: watch out for construction chockstone and potential sieve just below R1 where the slot narrows.
R2-70m NA-TL Flagstone Falls
Last canyon exit: bail out left up gully. Fresh rock falls at the bottom - a far bit of loose broken rock.
If you have enough rope to get to the far ledge, skip this rap. We skipped it by extending the rappel line before pulling the smooth operator. Probably need a 90m rope to skip the rap safely (recommended to skip).
Crack construction TR, or parallel crack TL. May need a bolt.
Traverse down and out along ledge on true right. Next anchor near grassy clump.
Chock stone thread through. Out of Main Falls and down cliff - Approximately 65m to tree.
Tree multi-pitch 40m to rocky ground
Last falls of the main Flagstone Falls.
Wisp Falls flows in here.
R7-20m NA-C Optional Gorge
Scramble around left
White Adder Creek (signposted Black Adder Creek) flows in here.
R8-15m NA-TL Optional Three Falls
15m to a swim
or scramble around left on scree slopes.
R9-20m NA-C The Drop Off
Scramble around right
R10-15m NA-C Optional Gorge
Scramble around right
Swim, scramble, and rock hop out to Garrawalt Creek. From here, you may have enough time to go upstream 900m to the Wall of Waterfalls (Lower Garrawalt Falls).
Watch for crocs in the lower creek when exiting.
Your team should have good navigation skills and appropriate experience.
Find your local canyoners and ask for beta on the FNQ Canyoning Facebook group.
WHAT YOU WILL NEED
- Experience in abseiling (there are some technical challenges)
- Enough rope for the longest rappel
- Rappel devices, prusiks, and webbing
- Rope protectors
- Grippy shoes on smooth, wet granite rocks
- Food and snacks for the trip
- About one litre of water to hike to the top and a way to sterilise your water from the creek
There are various natural anchors throughout the canyon, however, it is not unusual to come across damaged trees, especially after large flooding events. Please use sound judgement when considering previously installed anchors, like tape slings, ropes, and other textiles. There are no bolts in this canyon.
Along the route there are various sections of wet, slimy, and dry rock, as with all canyon environments. Please be mindful of your traction and regularly test your grip throughout the route as you cannot rely on the colour or texture of the rock to determine its safety against slippage. Take caution when near cliff edges.
No responsibility or liability is taken for any harm, death or loss of property resulting from the use of this article. You must carry anchor building materials, be experienced and use your own judgement when canyoning. Flooding events can strip anchors and change the canyons layout and conditions. Improper and insufficient experience will result in serious injuries or in many cases death. Always respect all signs you encounter and take everything in you brought with you.
