Good loop. I rode up out of Llanuwchllyn. But this ride would work very well starting in Bala. The section up around Arenig is great. A few gates to open/close, one farm to go through....but this is a good alternative to the sadly hobbled Bala Loop (Vyrnwy).

Just sublime when sunny, and even if not, the kind of narrow lane where you can ride along nice and relaxed.

Typical rural stone built bridge in a gorgeous country setting. Cycling along these back lanes and seeing these structures is like being in an open air museum.
