There are two buses an hour between Holyhead and Bangor
However, they are not at half hourly intervals
One is the X4, it’s supposedly the express route, but wanders around the houses quite a bit
The other is the 4, except it doesn’t go to Bangor it goes to the town of Llangefni where you can connect onto Bangor on the 4A, except in Llangefni the 4 just becomes the 4A without anyone mentioning it. (Is your head hurting yet!)
Neither route goes down the direct route to Bangor, both crossing over the A55 main road on multiple occasions heading off down to random villages (I know that’s the purpose of a bus route, not sure its the purpose of an express route though).
At one point we even went through a village called Llanddaniel Fab. I don’t think Fab has the same meaning in Welsh as it does in English though.
I thought that the locals would know what was going on, but on several occasions I heard comments like “Oh, this ones going this way today”.
Perhaps I should have just taken the train instead!
