We took the train on the Chester to Holyhead line (from Flint in our case) to Llandudno Junction and then got a minicab from outside the station. We took a taxi back to the station as well from a selection of phone numbers provided by the winery. About a ten minute ride and I think it was something like £6 each way. Getting the taxis was not a problem. I don't think that the bus route goes past - the winery is down a narrow country lane which means that walking is not advised, especially after you have had a few drinks.

I do not recall them saying that they were but I am sure that if you email them they will tell you Regards Colin
