　　The Youth Hostels Associations of England and Wales and Scotland have more than 400 hostels, many of them in lovely countryside. They're a very good idea for travelers of all ages and families too, not only are they cheap and friendly, they're also good places to visit. Everyone in a Youth Hostel helps with the housework and prepares their own meals, though some hostels offer cheap meals too. As Youth Hostels are popular, especially in summer and at I3ank Holidays, it's a good idea to book. The YHA also organizes special interest holidays for different outdoor sports, activities and interests.

　　To use the hostels you have to be a member. The cheapest way to do this is to join a YHA in your own country that is a member of IYHA. This makes finding a hostel and booking easy too, these association can offer you with the International Handbook, which has addresses and information about youth hostels in many countries, and with advance booking vouchers forms you can use to book a place in youth hostels in other countries.

　　If you can't join in your own country, you can ask for an International Guest Card, either before you come or when you're in Britain. Write to or visit YHA Services for International Guest Cards, maps and handbooks, they can also offer information about booking hostels, travel and special interest holidays.
