In Bulgaria, favourable starting points of an ascent are the villages Klyuch, Skrat and Gabrene. In North Macedonia, these are Smolari and Sharena Cheshma. In Greece these are Platanakia, Kalochori and Kastanoussa. Every August since 2001, an international excursion to the peak is organized under the motto "Balkans Without Borders".
