Kamenáč (936 m a.s.l.), known in German as Aschberg, sits right on the border between the Czech Republic and the German state of Saxony — a summit that belongs to two worlds at once. The actual peak lies on the Czech side in the village of Bublava, but just a short walk away you'll find a German observation tower, a youth hostel, and a charming scatter of old mountain farmhouses known as the Aschbergsiedlung.

The landscape here is classic Ore Mountains: dense forests opening onto wide ridgeline views. The summit itself is a modest granite outcrop crowned by a historic Royal Saxon Survey column — a first-order triangulation station numbered 24, now a piece of living geodetic history. Nearby, don't miss the 'Tři skalky' ('Three Rocks'), a striking cluster of boulders shaped by woolsack weathering. The panorama stretches over Bublava and Klingenthal all the way to the Slavkov Forest and the heights of the Upper Palatinate Forest. In winter, the mountain transforms into a proper ski destination, with a downhill slope and the Kammloipe cross-country ski trail connecting Mühlleithen to Schöneck or Carlsfeld to Johanngeorgenstadt.

• Bublava (Czech Republic) — marked hiking trails lead from the village centre towards the border ridge, moderate difficulty, approximately 45–60 minutes.
• Aschbergsiedlung (Saxony, Germany) — short approach from the border settlement, easy, approximately 20–30 minutes.

• The summit straddles the Czech-German border — free crossing within the Schengen Area.
• A youth hostel is located next to the observation tower on the German side.
• The historic Saxon triangulation granite column on the summit is a protected geodetic monument.
• A named viewpoint below the hostel, the Paul-Apitzsch-Blick, offers one of the finest views over the Saxon Vogtland.

Glassmakers once came to these slopes to exploit quartz veins and the vast surrounding forests for their furnaces — a craft history that shaped this corner of the Ore Mountains long before the ski trails arrived.
