10 days and BritRail advice

The passes can be very good value if you are travelling most days on long distance trips first class in peak time, ie the travel is the main point. Anything else and it is much less clear cut whether it is a pass of some kind or point-to-point tickets or even local rover and rangers.

Not much time to see anything with only 10 days. Or do you mean 10 travel days ?
London > Salisbury > Bath > Cheltenham > Manchester > York > Durham > Edinburgh > Glasgow > Lake District > Liverpool

Unless you are a train buff and the actual train travel is a large part of your experience, I would suggest that with only 10 days, you limit yourself to England plus either Wales or Scotland to avoid spending most of your time in transit.

BritRail passes can be good value if undertaking lots of long distance travel, but check with the operators (Virgin for England to Scotland travel) and price up if this can be done more economically by buying individual tickets. Travel is usually cheaper after 9.30 or at the weekend and buying 12 weeks out.

There's not a 10-day version of the BritRail Pass. Options are for 3, 4, 8, or 15 days, whether you buy the consecutive-day version or the flexi pass for travel spread over a month-long window. If 10 days is your total time in Britain, then you're probably choosing between 4 flexible train days for $295 or 8 consecutive train days for $333. Prices are lower if you'll complete travel by Feb. 28 or if you don't include Wales and Scotland.
