The mother – in law has a caravan at Conwy, been going for a few years now. We are up ther Saturday as well.
If you want a nice ride for 2-3 hours, start where Lowey has shown, go up to the standing stones don’t go down the drop which will end up with a bugger of a climb out of Rowan. Go straight on and you will meet the road up from the Rowan YH and as binners says miss out drum.
That might be just doable in 3 hours.
and missing those bits out still makes it a great ride 😀
The other option is to go to the first cross over point, and drop back down to the road, as on Loweys return leg and try a few of the trails around the mountain next to the A55, loads to do and ride around there.
