A closer look
The Pieniny mountains are a compact range that rises sharply from the Dunajec River, which has been the defining element of the landscape for millennia: the river cut the gorge through the limestone and dolomite ridges, creating a corridor of near-vertical canyon walls that on the Slovak side reach 300 metres in places. The gorge itself, about 21 kilometres long and shared between Slovakia and Poland, is one of the most dramatic river landscapes in Central Europe — narrow enough that the water and the sky above it fill your entire field of vision from a boat, with the walls closing in on both sides as the current quickens through the rapids. The river forms the border, and the flat-bottomed wooden boats called plty have been navigated through the gorge by local boatmen for over a hundred years, a tradition that has survived as a tourist experience without losing its original character.
The boats are built to a traditional design and are poled through the rapids by two boatmen using long wooden poles, a technique that requires precise knowledge of the river bed and the current patterns. The plty are uniquely adapted to the Pieniny water conditions: flat-bottomed so they can navigate the shallows and scraped over gravel bars, narrow enough to pass through the narrowest sections of the gorge, and light enough to be carried over the portage sections when the river level drops in late summer. The journey takes about two hours from Červený Kláštor to the Polish village of Sromowce Wyżne, with the gorge walls providing shade and the river keeping the air cool even on hot days.
The monastery of Červený Kláštor (Red Monastery), whose ruins sit above the gorge near the departure point for the boats, was founded in the 14th century as a Carthusian house and later became one of the most important monastic communities in the Spiš region. The red colour from which it takes its name comes from the sandstone used in its construction, which weathers to a warm terracotta in the afternoon light. After the dissolution of the monasteries under Joseph II in the late 18th century, the buildings fell into ruin, but enough survives to show the original layout of the cloister, the church and the chapter house. The monastery became a popular destination for Slovak and Polish painters and writers in the interwar period, and the tradition of artistic retreat continues today in a more modest form.
The Pieniny landscape changes character through the year: in spring the river runs high and fast with snowmelt from the Carpathians, in summer the gorge is sheltered and warm and the boats run continuously, in autumn the beech forests on the canyon walls turn orange and rust, and in winter the gorge takes on an austere beauty with ice forming on the rock faces and the river running cold and clear. The whole area is a protected landscape reserve, and the management plan limits commercial development so that the boatmen tradition and the natural character of the gorge are preserved for the future.
