National Blue Trail

The National Blue Trail (in Hungarian: Országos Kéktúra, Kéktúra or simply OKT) is a national trail in Hungary incorporated into the European Long Distance Walking Route E4. The route starts atop the Irottkő Mountain (884 m) on the Austrian-Hungarian border then cuts across Hungary eventually ending 1,168 km later at the village of Hollóháza by the Hungarian-Slovakian border.

'). The name of the Kéktúra (Blue Trail) is a reference to the marking of the path itself: it is a horizontal blue stripe between two white stripes. All segments of the trail are freely accessible to the public; no fees have to be paid or permits obtained, there is only one ferry to take over the Danube between Visegràd and Nagymaros where you have to purchase a ticket.

During its course the Blue Trail visits arguably the most beautiful natural and man-made sights of Hungary, e.g. more than a dozen forts and castles, lookout towers, three World Heritage Sites of Hungary (the panorama of Budapest from the hills, the old village of Hollókő and the Stalactite Cave of Aggtelek), Lake Balaton, the Danube Bend, and the spent volcanoes of the Basin of Tapolca, etc.

According to the latest GPS survey conducted in 2020, its total length was measured to be 1168.2 km and the total elevation change (climb) was found to be 30,213 metres in a Western-Eastern direction over the whole route.

History of the National Blue Trail

The National Blue Trail (simply Blue Trail, or Tour) was the first long distance walking route not only in Hungary but in the whole of Europe. Its path was first signed in 1938; its length was 910 km in that time. A lot of Hungarian hikers began the completion of the Trail after World War II, so the Nature Rambler Section of the Lokomotív Sport Club of Budapest announced the National walk on the "blue" hiking path in 1952.

The Nature Rambler Section's Committee of Railway Employee's Union developed this issue on the national level in 1953, and published the first brochure, which showed the whole route in map sketches.

Later, organisation and control of the National Blue Trail movement was taken over by the Hungarian Rambler's Association "Friends of Nature" (MTSZ) in 1961.

But the Blue Trail was known only among hikers until the beginning of the 1980s, when Hungarian TV broadcast a series about the route of the Trail. The organiser and editor of this series was Pál Rockenbauer, who at that time worked in the editorial office named "Natura" of the Hungarian TV. Pál Rockenbauer organised a small team and they completed the National Blue Trail during 76 days in an east-west direction. They carried everything (cameras, films and other equipment) in their backpacks and undertook the whole project without any external help.

Their work was very successful: the series drew people's attention to the National Blue Trail. 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.

Validation of completion

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 1990 HUF, about 5,5 Euro in 2020).

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.

The stamp of Bányahegyi erdészház (forester's lodge of Bányahegy) was stolen on the date of the hike, so the participant had to find another place to obtain a validation in his book. This was the pub named "Hubertus" in village Tardos - its distance is about 3 km from the original stamping place. There are two similar stamps, because the hiker finished here a hike and began another one later.

Usually the hikers have to start or finish a trip at a checkpoint. In this case, they have to stamp twice at same checkpoint: at the finish of a hike and at the start of the next hiking trip if these are in two different date. If this checkpoint is at the beginning or the end of an official section of the Blue Trail, there are two boxes at this checkpoint in the personal completion brochure. In other cases there is only one box, but the hikers have to stamp twice: first in the box and later above or below it - where they can find enough place. Of course if somebody only reaches a checkpoint and goes further, one stamp is enough.

Photos are accepted if they show the place and the person together. After the completion of the whole path of the Trail, the brochure has to be taken or sent to the Hungarian Ramblers’ Association in Budapest or local to a branch, where the completion will be checked and validated, after which a commemorative badge is issued.

Awards for the completion of the Blue Trail

Anyone who completes the Blue Trail is eligible for the Blue Trail Badge of MTSZ. This is free of charge to members of the MTSZ; non-members have to pay production costs. The badge is an irregular quadrangle with a road leading towards mountains with a blue signed post and below in red stripe with the following: "Országos Kék-túra MTSZ". MTSZ prepares and hands over the badge - if it is possible - during a small ceremony. A record of those who have completed the trail is also kept by the Association.

The number of people who have completed the Trail is more than 4100 in year 2007. It is also possible to complete the Trail more than once.

There are three sections on the route of the Blue Trail which have their own badges. These can be obtained without completing the whole Trail; however, by completing the Trail one is also eligible for these.

- Dorogtól Nógrádig túramozgalom (Hikers’ Movement between Dorog and Nógrád) through the Pilis Mountains, Buda Mountains and Börzsöny Mountains – 138.8 km, 4490 m total climb.

- Mátra-Bükk útjain túramozgalom (Hikers’ Movement through the paths of the Mátra and Bükk Mountains) – 120.0 km, 4360 m total climb

The Children's Blue Trail (GYKT) can be completed by children between the age of 6 and 14 hiking 300 km on the Blue Trail. It is divided in 9 regions:

- Mountains of Kőszeg – Little Hungarian Plain

- Balaton Uplands

- Bakony Mountains

- Vértes Mountains – Hilly Country of Gerecse

- Pilis Mountains – Mountains of Buda

- Börzsöny Mountains – Hilly Country of Cserhát

- Mátra Mountains

- Bükk Mountains – Hilly Country of Aggtelek

- Hilly Country of Cserehát – Mountains of Zemplén

Children who complete at least 50 km distance in a region obtain the regional badge of Children's Blue Trail (GYKT); at most one badge can be earned in each region independently of the distance covered. If the combined length of the completed sections reaches 300 km, they obtain the GYKT badge. In case of organising and leading a group of children, the leader can obtain the badge, if the number of the children is at least 6.

Completion of GYKT counts towards gaining the OKT badge as well. The validation of the completion is the same as in the OKT.
