This sector consists of a group of limestone cliffs towering above the tiny village of Kostolec. The three rock towers and the views were probably best described in 1987 by Jozef Boško, in a mountaineering guide from Kostolecká úžina and Bosmany: “Bosmany is above all beautiful. It is beautiful for its landscape, but also for its climbing. Standing in the middle of fields and meadows, the cliffs seem to float in a sea of light and silence. During spring and autumn evenings, when the sun takes its time to set in a great arc behind the wide landscape and when the sporadic sounds from the fields and the village accentuate the silence in man. ... The whitish walls of the Kostolecká and Manin Straits reflect the colour of the western sky, and the bluish ribbon of the Javorníky mountains winds in the distance.”
It should be noted that the name Bosmany is the only original name of the climbing crag in the entire Manín and Kostolecká Straits that originates from local residents. Other crags have been named by climbers. It is said that the name bosman means cake. And sure enough, the towers remind of three cookies rising above the village, a temptation for the climbers to bite into them. And so it happened in 1946. Today, the area offers more than 30 routes. When viewed from the village, the towers are marked from right to left as Bosman I, II and III, occasionally also referred to as the right, the middle and the left Bosman.
