Thanks Ian, I've just looked it up on Google street view. It's quite remote but set in a stunning location with beautiful views over to the Carneddau
We have walked down that old road a number of times in the past and must have gone past the cottage. One such walk sticks out in my memory more than the others and that was when Tellytubby arranged a walk from Bethesda over the Carneddau before crossing the A5 and walking down that lane to the Ogwen Cottage and a walk around Cwm Idwal before catching the bus back to Bethesda.
At the Ogwen cafe I fancied a coffee so we stopped and I asked the guy who served us "when is the next bus back to Bethesda".
The guy replied about 6 months as the bus company had gone bust!
We skipped the intended walk along the lake and walked back along the A5. At least it was a dry day and we even walked over the old packhorse bridge that goes under the A5
