Thaya River Border Crossing Bridge (Thayatal National Park)

Highlight • Bridge

Don't forget your passport when hiking to the Czech Republic! A place steeped in history that brings back memories of terrible personal fates! We met a man whose family was separated by the border for many years; they only saw each other on occasional visits. Bunkers, customs houses and the remains of the Iron Curtain in Čížov are reminders of a bad past. How nice it is that people from both countries can meet again while hiking in the large shared national park.

Kaja Castle Ruins

Highlight • Castle

Relatively well-preserved castle ruins. Definitely worth a detour if you are hiking through the Kajatal from the Thaya up towards Merkersdorf. It is not always open though.

Hardegg border crossing

Highlight • Bridge

This border crossing is probably one of the best known, but also one of the most beautiful crossings between Austria and the Czech Republic. In the monarchy, the border between Moravia and Lower Austria (Austria below the Enns) was open and permeable over the iron bridge built in the 1870s, and even after the emergence of the first Czechoslovak and the first Austrian republics and the construction of the two customs houses, it still prevailed until 1945 brisk border traffic (after the annexation of the German-Moravian areas to the National Socialist (Greater) German Reich and what was then the Lower Danube in October 1938, the border had of course temporarily disappeared). In 1945 the border at the bridge was closed after the reestablishment of the Czechoslovak Republic (the German Moravian residents of Čížov/Zaisa were expelled across this border in May 1945). In the course of the emergence of the "Iron Curtain" during the Cold War after 1948, the border was hermetically sealed off by the CSSR. The area up to Čížov was a restricted area. One last remnant of barbed wire and watchtower can still be seen at Čížov today. The road surface of the bridge was removed, making it impassable. Incidentally, the bunkers partially visible on the Czech side do not date from this period, but are part of the "Czechoslovak border wall" from the 1930s, which was built in the face of the Nazi state's increasingly aggressive foreign policy (a legitimate concern given the events of October 1938 and March 1939 with the occupation of Czechoslovakia). For decades the bridge fell into disrepair. I still have the picture from the late 1980s in my head: the bridge on the Czech side was rusted right down to the middle - on the Austrian side, at least a makeshift effort should have been made to preserve it. After the turn of 1989/1990, the border was reopened and the bridge was repaired on both sides. Now the Czech side was freshly renovated and more beautiful than the Austrian side - today, about 30 years later, these differences are almost no longer recognizable, apart from the different shades of green. Since there is a lot of pedestrian and cyclist traffic at the border crossing and on the bridge, especially in the summer months, you should adjust your speed with the racing bike accordingly.

Thayabrücke Inn

Highlight • Restaurant

The inn was a real highlight for me. I can really recommend stopping here at the end of the tour and having something to eat and/or drink. The food was excellent and the service friendly. Open daily from April to October. Mon.–Thurs. 11 a.m. to 4:30 p.m., Fri.–Sat. 10 a.m. to 8 p.m. and Sun. 11 a.m. to 7 p.m. Kitchen opens at 11:30 a.m. When I'm hiking nearby again, I'm looking forward to stopping here again! The business doesn't rely on the fact that there isn't much to go to in the area anyway - no, even the "day trippers" who may never come back here get excellent quality!

Hardegg may be a small town, but it has a lot to offer. A large castle, the clock tower and a great panorama. A stop here is definitely worth it.
