The terrain on these routes is characterized by the park's dramatic glaciokarst landscape. You'll encounter challenging climbs through mountainous passes, U-shaped valleys, and areas shaped by ancient glacial erosion. While many sections are paved, expect varied surfaces that require a touring bike capable of handling ascents and descents across diverse natural settings.
