The history of York stretches back to Roman times. Few cities look as completely medieval as York as many buildings have remained more or less unchanged for centuries. With its ancient wooden houses and narrow winding streets, the whole city gives off an atmosphere of history. Today, these streets contain a fascinating variety of shops. York has been called “the City of churches” for there are no fewer than 17 pre-Reformation churches within the city walls. The pride of York is the huge and magnificent Minster which towers over the whole city. It is thought to contain the largest area of medieval coloured glass in the world. If you don’t want to join a group tour, there are cassettes - complete with Sony Walkman - which will tell you all about the city.
B Dover
The white cliffs of Dover are familiar to millions of travellers. Dover, the gateway to Britain, is the busiest ferry port in Europe. In times gone by, the town has been host to kings, armies, pilgrims and all kinds of travellers. Ancient monuments and ruins testify to Dover’s long and fascinating history and today the town offers a great deal to interest visitors all the year round. On a fine day, the harbour itself offers excellent walks. Particularly recommended is the Prince of Wales Pier at the end of which you will find a viewing place with a splendid outlook over the entire port, the white cliffs and Dover Castle. With two direct trains each hour from London Victoria and London Charing Cross, Dover is ideal for a day-trip from the capital.
C Portsmouth
This is a very special year for Portsmouth. The historic military city is celebrating its 800th anniversary and we want you to join the party! Apart from special events such as military displays and parades, there is always something to do in Portsmouth. Visit our historic ships, explore under the sea in our Underwater World, enjoy the year-round Resort Centre - the possibilities are endless.
And once you’ve had a taste of what the town has to offer, why not hop on the luxury cruise vessel Solent Enterprise and enjoy a leisurely day trip to the beautiful Isle of Wight?
D Oxford
Oxford has a timeless beauty which is found at every twist and turn of this ancient university city: in the soft golden stone of the college buildings and the peaceful courtyards and gardens. There is so much to see and do in Oxford. Take the “Guide Friday” open-top bus tour to see 25 of the 35 colleges - it leaves every 15 minutes and one ticket lasts all day. Or explore on foot-guided walking tours start at the information centre. Get a bird’s eye panorama of the whole city from the top of St Mary’s. Take a journey through time at the unique Oxford Story exhibition in Broad Street. And then there are the shops. Lose yourself in famous Blackwell’s bookshop in Broad Street - with the largest display of books for sale in one room anywhere in the world. The Gallery at Gloucester Green has a busy cosmopolitan atmosphere, with speciality shops, pavement cafes and street entertainers. And of course there are many big name shops too.
E Llangollen
For six days every July, Llangollen becomes the cultural centre of the world, attracting choirs, musicians, folk singers and dancers from all continents. Over 40 different countries are represented with colourful national costumes, taking part in daily competitions and performing in evening concerts. But if you are more of the outdoor type, why not try riding the rapids? Experience the excitement of white water rapids on the River Wild. All equipment can be hired. Llangollen is also a centre for outdoor clothing and equipment for climbing, walking, mountain biking and camping. From Llangollen wharf you can embark on a 45-minute horse drawn boat trip along the river or, on certain days, you can go for a longer journey on the Thomas Telford, which has refreshments on board to add to your enjoyment.-
