The loop from Llandrillo going anticlockwise is very steady and pleasant. But be prepared for substantial bog trotting in the central part of the valley passing the area marked as Gwern Wynodl. Even with newish goretex boots, we came away with wet feet. Good boots and gaiters, or wellies for that section highly recommended. Return section (first section if doing it clockwise) is also pretty boggy in parts. It also seemed like a bit more of a slog doing it clockwise.

The track from the East is broken but doable on a gravel bike - I had to push the last few hundred metres. Awkward terrain - large stones - and plenty of puddles - but a fabulous day on 2 wheels!

About 5ft deep and 8ft in diameter, enough to sit and shelter from the wind. Good place to stop for coffee for 5/6 people.

The Wayfarer Memorial Traverse is a very rough but wide track that can be best described as a good gravel ride for the most part. It is best ridden on a mountain bike if you want some comfort, otherwise a gravel bike or other tough touring bike will manage it if you have appropriate wide 40mm+ tyres. Either way be prepared for a bit of walking on some of the tougher stages but don't let this detract from the fact that overall this is a classic route totally rideable for the best part and with great views that is well worth the effort. Best done in good weather. If in doubt have a read of the following article: https://gravelshack.life/north-wales-the-wayfarer/
