If it is scenery that you are after then why not look at a Lakes and Mountains holiday? There are so many options to choose from including the familiar Italian Lakes of Como, Garda and Maggiore, Switzerland, Germany, Austria, Slovenia or Poland.
Naturally many of these destinations are excellent for walking, but they are also extremely easy to combine with a rail holiday, cruise or city break. You could also take the family with a number of amazing activities including glacial skiing in some parts of the Alps in the summer.
If you are looking at further afield, then we can certainly recommend the Canadian Rockies and travelling on the famous Rocky Mountaineer Train. You might also like to add a cruise to Alaska to give a contrast of land and sea.
