How to book cheap train tickets from Cardiff to Mountain Ash

Travelling in off-peak train times

Split Tickets to save an average extra 30%

Splitting tickets involves buying separate, cheaper tickets for different parts of your journey on the same train instead of just one ticket for the entire trip. For instance, if you're travelling from Cardiff to Mountain Ash, you might find that purchasing a ticket from A to C, then C to B costs less than a direct ticket. This method is perfectly legal and often doesn’t require leaving your seat.

Book in advance to save an average of 61%

Did you know that purchasing Advance Tickets can significantly reduce your travel expenses? On average, these tickets can save you an impressive 61% on fares. The best part is that the earlier you book (ideally up to 12 weeks in advance), the greater the savings!

Group travels to save 1/3
