Dlouhý vrch lies in the Bohemian Central Mountains, about 5 km north of Litoměřice.
One of the largest rock massifs in the Bohemian Central Mountains, consisting mainly of Tephrite (peaks) and Tephrite tuff (slopes), is located about 5 km from Litoměřice. A forested hill stretches 5.5 km from north to south, about halfway, its initially narrow part, now splits into fork-shaped massif and stretches to the southeast and southwest, and the span of these to branches reaches about the same length as the main ridge. Apparently due to its considerable fragmentation, it was divided into several separately named subunits: Vrchovina (676 m) with attached Špičák (608 m) and Babinský or Rýdečský hill (551 m), Dlouhý vrch (655 m) and last but not least the Panenský rock (607 m). The southernmost part of the south-eastern promontory is called Křížová hill (590 m), with a protruding, remotely visible rock outcrop called Krkavčí or Kavčí vrch (500 m). This about 30 m high rocky structure has at its top several lookout points, including a marked main lookout, facing southwest, with views stretching from Mělník through the Elbe and the Elbe regio to the nearby Soví Hill or kočičí Castle - Kočka, Mostka, Litoměřice, Radobýl, Bídnice, Lovoš and the panorama of more distant hills from Košťálov to Milešovka and Kletečná, partly covered by the nearby Plešivec and Hradiště, which closes the view. In the past, the rock served as a training wall for climbers from Litoměřice.
The whole large hill is interwoven with many forest paths and gravel roads, on which three tourist routs go, the yellow rout between Staňkovice and Skalice Poustevna intersects with the blue rout at the highest point of Dlouhý vrch. The blue tourist rout goes from Lbín over Křížová hill to Pohořany. From the Tašov Ovčárna crossroads, a marked bike path passes along the foothills, which later crosses the yellow sign and leaves just under the Panenský rock on the road near Myštice.
Certainly the most beautiful parts of this interesting hill can be seen on the way along the yellow rout from Staňkovice, massive boulders with amazing, age-old specimens of beeches, between which a few thin streams meander – the beginnings of Chudoslavický brook. Just a little higher rock formations await you. As you continue to Křížová hill, nice partially obstructed views open up through fresh and older, constantly changing cutouts, west to Varhošť and Radobýl, east to the Třebušín basin with Kalich, Trojhora and more distant Sedlo. From the blue rout towards Lbín, Homolka and Varhošť it is also possible to see some more distant hills: Radobýl, Hradiště, the tip of Lovoš and Házmburk in the background.
The most open view, of Milešovka and the adjacent part of Bohemian Central Mountains with Varhošť in the foreground, is from Vrchovina, to which, however, the tourist rout does not go, it is necessary to use a forest path and navigate yourself with a map. Fans of history, although recent, will see a number of remains of various ruined buildings on this route in a former military zone. From the slowly overgrown slope there is a partial view of the north-eastern panorama of the hills in the foreground with Kukla and Babinský vrch.
In addition to the Chudoslavický brook, some other streams originate on Dlouhý vrch, on the western slope of Dlouhý vrch Pokratický brook, on the southern slope of Panenský rock the Močidelský brook and below Babinský hilltop the Trojhorský brook.
