The first time I heard about a walking trail perched on top of the Karkonosze (Krkonoše in Czech) Mountains that meanders through the border between Poland and the Czech Republic multiple times, I was instantly intrigued. It is a moderately difficult trek of about 30 kilometres while traversing most of the prominent peaks of the Karonosze mountains in the Sudetes range. The first and the most obvious reason for this newfound excitement was my lack of trek fitness, and the second was an opportunity to witness the crisscrossing of boundaries between these two countries.
