Access rules for Agen Allwedd.
Permit/key application form
No tackle is required for the main routes, although a 10 metre handline is recommended for the climb down at Keyhole Chamber, where P-bolts are installed. These are the only official fixed aids in the cave. The integrity of in-situ ropes is not not guaranteed and you use them at your own risk.
Certain sections of the cave are prone to flooding. In moderate
flood, the area around 3rd Boulder Choke sumps, and in heavier flood
conditions 2nd Boulder Choke and the narrow section of Turkey Streamway
above Northwest Junction become impassable.
Lower Main Stream becomes impassable and can sump upstream from Southern Stream Passage junction. Also, Maytime floods dramatically.
These are for guidance, and are for fit, experienced cavers and do not include any allowance for route finding.
