Where to go from London for a week?

Berlin, Salzburg, Prague and Madrid might be good options. I don't think you can fly back to the US from Salzburg. They offer sights and day trips for variety. Have fun

You have given no indication of your interests, so it is difficult to advise. Much of Europe is within half a day of London.

The weather isn't likely to be great in March in most of Europe - is this a concern?

Have you been to Rome? Venice?

Lisbon is good as a base. Madrid could be very cold in March, but southern Spain would be warmer. Berlin is great for a week as there is plenty to do.

Without actually leaving London overnight you could do Hampton, Canterbury, Dover, Salisbury, Oxford, Cambridge, Bletchley Park, and more.

In the UK for a week you could go anywhere: Edinburg, Wales, York, Cotswolds, or south. You could fly for a week to just about anywhere in Europe afforably. Germany? Spain? Portugal? Russia? Czech Republic? Hungary? Morroco?

You'll be reasonably close to Stansted airport so have a look at this route map for Ryanair for some inspiration:

Although geographically Stansted is the closest airport to High Halstow, it will take 2.5 - 3 hours to get there by public transport. Gatwick airport is a much shorter journey, requiring only one train change, rather than 2/3 trains and the London Underground.

As compared to the rest of Europe, Spain is a good bet for budget travel. I suggest flying to Sevilla and spending 4 nights there. You can easily visit Cordoba as a day trip. There is plenty to see and do there to fill your time without museums. And they have lots of tapas! Take the AVE train from there to Madrid and spend the rest of your time there with a day trip to Toledo.

Travel agencies in the Uk have a wonderful thing called Short Breaks. You can fly or train anywhere in Europe for a 3-5 day vacation. Costs include hotel and airfares and often transfers. Google short breaks and see what you come up with. Have your friends check with a local agency, they should be able to get brochures. One advantage with the short breaks is that you can often pick up a last minute reservation......

First, I would suggest deciding if you want to stay in the UK for that week after the visit in London. If you prefer the UK, spend the week there, lots of places of interest.

Leaving the UK after London, go to Berlin. Fly there. I have a long time friend, never has been in Europe, a total newbie, whose top three priority cities to visit in Europe (assuming he ever gets his act together, etc etc,) with at least three weeks time, are London (obviously), Berlin, and Vienna, ie, a week in each.

In your case if you choose Berlin (or Vienna), fly from London.

Although I share Fred's appreciation of Berlin, it's not a place I would recommend in March for someone mentioning nature and food but not much interested in museums--though it has a lot of WWII and Cold War historical sites. After March time in England, I'd definitely be looking for sunshine, and I think southern Spain is just the thing for that.

Ireland is where I would go. Dublin has amazing food and great history. If you venture out of Dublin, there is beautiful scenery with great hikes.

you can go to Scotland from London for a week. Scottish castles are, in their opinion, the most famous, most haunted, most romantic and best Places are here to see. you will enjoy your London with Scotland tour.

I suspect you may well be craving sunshine and warmth too! A lot of Mediterranean resorts may only just be springing to life but the last week of March will be Easter holidays (certainly in the UK) so there might be quite a lit heading out for an Easter break. The French Riviera (Nice), Croatia, Greek islands, Madeira, the Azores, Morocco....

The above examples are because you get a cheap package tour to one of these destinations, but if you want a city try Lisbon in Portugal or Basel in Switzerland (that won't be so warm though).

Hi, I'd second the other's replies and say you could visit Scotland - if you like nature there are beautiful hikes just north of Edinburgh in Fife. (check out information on the Fife Coastal Path. It will be cold though.

You could also fly to Portugal or Spain. Indeed there are lots of low cost airlines offering flights to Lisbon or Andalucia (or fly to Madrid and take the train south). You'll find delicious food, lots of history and lovely nature in southern Spain. I'd recommend Sevilla, Granada and Cordoba. You could make one of these your base and explore by car or bus. Same with Lisbon.
