I'm riding to Lake Bala to go camping (in what looks like feckin horrible weather) this Friday till Sunday, if anyone else is going to be around those parts.
Just back from a week there. The two back roads to lake Vynrys (was that how it was spelt?) to the east, 1 from north of lake Bala & 1 from the south, were both outstanding - I think the southern road claimed to be the highest road pass in Britain. Take your walking boots; the Aranigs & Arans are unknown gems.
I used to live on the side of Arenig Fawr, you may have seen the cottages opposite the green tin chapel and red phone box I used to regularly walk and sometimes bike over the mountains there
