Your only public transport option is to get the train. Trains leave Cardiff Central at 9:30, 10:30 & 11:30. The train takes an hour and four minuets to get to Bath. The cheapest tickets is a group of 3 or 4 which will make a ticket cost around a tenner each, obviously you have to travel as a group. Allow at least ten minuets to buy the tickets at Central since the ticket office can be busy. The train normally leaves from platform 2 and gets in about ten minuets before so it's worth getting early if you want to grab your self a table.
Pubs in Bath
Okay, you don't need me to tell you the best pubs in Bath. There's the good beer guide for that. However her are some of my favorite pubs scored using the 2012 pub scoring system (see map). The scoring system is a little flawed here. It is designed for pubs in South Wales and is simply overwhelmed by the quality in Bath. As a result the scores are very high.
Coeur De Lion 83%*
This tiny pub's score is somewhat let down by its limited range of beer and cider. However given that the bar is the size of an ironing board this is understandable.
The Raven 92%**
A great pub popular with rugby fans on match day.
The Old Green Tree 93%*
A very small pub with a great range of beer. Visiting in the gent's toilets is like taking a ride on a ghost train: scary but entertainingly so.
The Pulteney Arms 89%**
A great pub tucked away in a side street that does excellent food. The beefburgers got very good reviews when I visited.
The Bell Inn 92%***
There is an excellent range of beer and ciders in this gig based pub. A sunny drinking area out the back make this stand out from other Bath pubs as does the bar billiards and fuzz-ball tables.
The Star Inn 92%*
A series of tiny wood paneled rooms make visiting the Star feel like a trip back in time.
