You walk easily at your own speed. So you can enjoy nature without any worries. Frequently you will find the blue dots. On difficult parts they are close to each other. If you continue on the main path you see less marks. Sometimes there are other marks that let you know that you are on the right track.
In addition to the dots there are the situation sketches and situation photos very helpful. Only three walks are not yet marked with blue dots. These are well explained.
A lot of people buys a gps-device to avoid doubts during the walks. This gps-device is a technical feat that shows you the way. A navigator, as in the car is all very common. You can use this also fine with hiking. If you recognise this kind of doubts, look a on the next page. There is a short gps explaination.
