Walking (hiking, backpacking, trekking, or rambling) is the oldest and probably the most zen way of getting around. You need time, but it's quite rewarding. With some training you can walk about 25 to 30 km a day (depending on the route and conditions).
There are walking networks around the globe, from the short day trip to walks that can last weeks or months. For example. a network of long-distance trails crisscross Europe (i.e. Tour du Mont Blanc). Based on a 'E' numbering system, the he E7 Atlantic-Black Sea for example allows you to walk from Portugal to Hungary. There are also walks that exist in individual countries.
