The National Blue Trail, or Országos Kéktúra (OKT), is a 1,170 km point-to-point hike across northern and Transdanubian Hungary, from Írott-kő on the Austrian border to Hollóháza on the Slovak border. A continuous thru-hike takes about 50 days and is best treated as a hard route: the walking is rarely technical, but the distance and roughly 31,000 m of ascent add up. It suits experienced long-distance hikers who want forested hills, towns, stamps and a major European waymarked trail.
Route Overview
The OKT runs west to east from the summit of Írott-kő in the Kőszeg Mountains to Hollóháza in the Zemplén Mountains. It crosses Kőszeg, Sárvár, the Bakony, Lake Balaton and the Balaton Uplands, the Vértes and Gerecse hills, the Pilis and Buda Hills, Budapest, the Danube Bend, the Börzsöny, Cserhát, Mátra, Bükk, Aggtelek karst and Zemplén ranges. The route is linear, fully waymarked with the blue horizontal stripe, and forms part of the European Long-Distance Trail E4 for much of its length. The stamp system, with checkpoints at huts, shops, stations and restaurants, makes section hiking practical.
History of the Országos Kéktúra
The National Blue Trail was first waymarked in 1938, originally at about 910 km, and is widely cited as Europe’s oldest long-distance marked trail. The national walk was formally organised from 1952 by the Nature Rambler Section of Budapest’s Lokomotív Sport Club, with management passing to the MTSZ in 1961. Pál Rockenbauer’s 1980s television series Másfélmillió lépés Magyarországon helped make it a national institution and gave it the “one and a half million steps” nickname.
Notable highlights
- Írott-kő lookout tower (882 m): The western start of the OKT stands on the Austria-Hungary border in the Kőszeg Mountains. Its stone lookout tower is a clear symbolic launch point for the full crossing.
- Lake Balaton and the Balaton Uplands: The route skirts the northern shore of Central Europe’s largest lake and crosses volcanic uplands, vineyards and the Tapolca basin. Hikers wanting more time here can also look at the Balaton Uplands Trail.
- Budapest crossing: Roughly halfway, the trail passes through the Hungarian capital and the Buda Hills. It is the only major city on the route and gives a rare urban reset on a mainly rural hike.
- Kékestető (1,014 m): The trail’s high point is also Hungary’s highest peak, in the Mátra Mountains. The summit is topped by a TV tower with a public viewing deck.
- Hollókő: This UNESCO World Heritage Palóc village in the Cserhát hills preserves traditional rural architecture close to the trail line.
- Aggtelek karst and Baradla Cave: The north-eastern section enters a UNESCO-listed karst area. Baradla Cave is one of Europe’s major stalactite cave systems, with tours requiring separate admission.
Challenges to expect
Expect a hard hike because of scale rather than technicality: about 1,170 km, roughly 31,000 m of cumulative ascent and many weeks on foot. Terrain is mostly forest dirt, gravel and rocky hill paths, with paved sections through towns and Budapest. Summer can be hot on plains and open basins; winter snow can affect the Mátra, Bükk and Zemplén. Carry the Kéktúra logbook if you want official completion.
