My husband and I are planning a UK trip in June of 2019. Any pro tips available, out there?
Ideas are fly into London, train to Edinburgh around day 4 or 5, then fly home via Edinburgh. Are there other cities, regions, or attractions that we should look into?

Thanks ahead!

Not really unanswerable . . . There are literally hundreds of wonderful places you could visit but with just nine days you really only have time for London and Edinburgh.

Is the total trip 9 days (home to home)? If so, you will only have 6.5 days free on the ground and .5 day will be spent traveling up to Edinburgh. If on the other hand, it is an 11 day trip / 8.5 days on the ground, Then London and Edinburgh is more doable.

Tips re what? Accommodations, transport, sightseeing, ££/expenses, meals . . . what?

Not much time for other places - maybe a day in York, right on train line to Edinburgh and for a first trip those two cities are great. Anyway booking your train well before the date you are taking it could yield nice discounts over full fare. National Rail Enquiries - Official source for UK train times and timetables is many say very easy to work in booking tickets - also check www.seat61.com for didactic help on doing that; general info British trains also BETS-European Rail Experts and www.ricksteves.com. There is also the overnight Caledonian Sleeper train between London and Edinburgh - check above sites for what to expect on night trains which also negates the need for a hotel that night and maximizes actual daytime travel time in Edinburgh (If you can sleep with a modicum of inevitable noise from outside the train!

While based in Edinburgh and after you have seen the capital, here are the "easy reach" nearby destinations that will allow you to get the most out of Scotland's wonderful landscape and scenery. Both along the seaside and in the hills

Head to the beach in North Berwick, just 30 mins east from Edinburgh by train or car: Here some pics to give you a visual sense:

Consider also St. Andrews in Fife, Stirling and Stirling Castle, or if you want to hit the Highlands, then Aviemore. To do the Highlands a car is best to really get out into nature, but the coastal towns near Edinburgh, like North Berwick, Kinghorn Beach on Fife or St. Andrews are great to do by train.

With less than 7 days total on the ground how will there be time for St Andrews, or North Bewick (nice but pretty far down the 'must see' list for a first time visitor). Aviemore - really? With 7 days divided between London and Edinburgh??? Kinghorn . . . without a car? Neither Kinghorn nor St Andrews has a train station so both would require a train plus a bus. Sorry but your suggestions really don't work for such a short visit.. Five days should be about minimum for London because of its enormous size, basic logistics and jet lag.

(And IF the OP actually means 11 days -- still not much time)

We are doing something similar in a few weeks. We are flying into Heathrow then catching a flight to Edinburgh staying 3 days. Then training from Edinburgh to London and spending 6.5 days there. We thought about other side trips but with the timeline we thought we would maximize our time in both places.

Maximize time in each place more by taking the overnight Caledonian Sleeper train!
