Tachovský vrch is a small but geologically remarkable hill in the Česká Lípa district, just south of Doksy. Despite its modest height, it offers rugged rock outcrops, boulder fields and sweeping views over Lake Máchovo - a surprisingly rewarding little summit.

The hill formed from phonolite that pushed up through Cretaceous sandstones and mudstones, creating an isolated volcanic ridge stretching northeast to southwest. Rocky outcrops crown the northeastern side, while steep southeastern slopes (40-50°) feature frost-shattered cliffs and boulder streams. Boulder scree also covers the gentler northwestern slopes. Mixed forest of spruce, pine and maple cloaks the hill, giving hikes here a quiet, woodland feel. From the northwestern slope and the quarry edges, views open toward the Ralská Uplands, Lake Máchovo, the Kokořínsko region and the České Středohoří highlands.

A large part of the hill's volcanic rock has been removed by an extensive quarry, meaning Tachovský vrch - once the highest point of the Jestřebí Basin - has lost much of its original shape.

• Village of Tachov (accessible by car) - continue on foot along an overgrowing path around the peak, demanding route, terrain can be hazardous

• Entry into the active quarry is strictly forbidden
• The path to the summit is dangerous - caution advised
• The site is operated as a working quarry by the company Eurovia Kamenolomy

Geologists recommend preserving the exposed phonolite outcrop once quarrying ends and opening it to the public, as it is a unique geological showcase of the region.
