Everybody got to know the Trail in Hungary and many people began the completion of it. A lot of hikers have the series on video or DVD at home. Pál Rockenbauer committed suicide in 1987 during a hike on the paths of the Blue Trail close to village Katalinpuszta at the foot of the Naszály Mountain. A wooden headboard column cherishes his memory on that place beside the path of the National Blue Trail. The whole route or its sections can be completed for amusement without any validation. However, the completion of the Blue Trail is a very important event in the life of Hungarian hikers, so generally they have their own personal completion brochure (its price is 1200 HUF, about 4 Euro in 2015). There are 147 checkpoints (stamping places) on the route of the Blue Trail. The participants have to validate the completion of the tour by passing all checkpoints. This can be verified by dating and stamping of the appropriate box in their personal completion brochure. It is required to stamp at every checkpoint. If this is not possible (because the stamp is not available or the hike is started or finished at a place without a stamp), it is acceptable to obtain a stamp from a nearby shop, mayor's office, etc. or taking a clearly recognisable photo of the location and the hiker. The National Blue Trail has its own stamps with the name of the appropriate places. They are located in pubs or shops in the villages, on railway stations usually in the ticket offices, but many times they are in the forest in their standard blue-white boxes equipped on trees or on the fences of forester's lodges. As can be seen on the picture in the left side, there are different types of stamps along the route of the Blue Trail. This picture is a sheet from a personal completion brochure, which is already validated by stamps. The stamp of Koldusszállás is located on a tree in its small iron box beside the access road of the hunter's lodge. It is a simple rubber stamp with the name of the place. At Gerecse üdülő (Children's holiday resort of Gerecse) the metal box of the stamp is equipped on the corner of the fence. This stamp is an iron stamp with chiselled letters. The stamp of homestead Pusztamarót is similar to the stamp of Koldusszállás. Its box is on a pine tree at the edge of the great meadow.
