Here you can follow my footsteps to some places around the world. The photos of my newer travels are all kept in my flickr collection
The Hitchhikers Guide to the Galaxy
Known to many as a fantastic sci-fi book by Douglas
Adams, the online version contains a good amount of travelling
information about many countries. Just enter "Germany" in the
search field, for example.
The German Youth Hostelling
Association
Here you find a list of all youth hostels in Germany including
details and prices. You need to have an international Youth
Hostelling membership card to stay there. It is also expected
that you bring your own bedsheets with you, otherwise you must
pay extra to rent them from the hostel.
The German Railways
The best way to travel in Germany is to use the railways (If you
don't have a car). The railway network is very tight, even small
villages have their own stations, but be prepared that the
trains are delayed. At their site you will find a timetable
system and information about special tickets. If you travel at
weekend, you might consider using the "Wochenende Ticket" and
save a lot of money.
The "Mitfahrzentrale"
organizes Hitchhiking for money. On It's website,
you can find offers of people with a car who will take you with them.
