Location mountain towards the mountains: Vřesník, Dlouhé stráně (with the peak of Mravenečník above it), Kamenec (1), and Medvědí hora (with the barely visible summit of Ucháč) Dlouhé stráně is situated in the central-western part of the
Hrubý Jeseník mountain range, specifically in the northern-western area called the Praděd Mountains. It is located on an arc-shaped side ridge that extends from Hubertka mountain to the Vlčí sedlo pass, being the highest mountain on this ridge. Dlouhé stráně is easily recognizable from a distance due to the leveled shape of its summit plateau, which has been adapted into a water reservoir and resembles the shape of a trapezoid. Additionally, the mountain stands out as the middle peak among three summits (Vřesník – Dlouhé stráně – Mravenečník), all of nearly the same height. The mountain is also clearly visible from the road surrounding the summit area of
Praděd, where it emerges to the right of the neighboring Vřesník mountain. It is easily noticeable and locatable from the nearby mentioned peaks of Mravenečník and Vřesník, as well as from the main ridge peaks of Praděd mountain:
Vysoká hole, Kamzičník, Velký Máj, Jelení hřbet,
Břidličná hora and Pecný. The mountain is bordered by: • the northeast by a pass at 1,093 m above sea level towards the Tupý vrch peak; • the east by the valley of the Jezerná stream; • the southeast by the
Pláň pass at 1,311 m above sea level; • the south by the valley of the Studený potok (2) stream () and a pass at 743 m above sea level towards the Nad Myslivnou peak; • the southwest by the valley of the Kamenitý potok stream; • the west by a pass at 1,302 m above sea level towards the Mravenečník peak; • the northwest by the valley of the Borový potok stream. All types of forestation can be found here: spruce forest,
mixed forest, and
deciduous forest, with variations depending on the location and orientation of the slope. The northwestern slope is forested with spruce. The northern and northeastern slopes are forested with spruce, gradually transitioning to mixed forests as the elevation decreases, with the northern slope even transitioning to deciduous forest. The upper parts of the southwestern slope are forested with spruce, transitioning to mixed forest (
Kamenná stráň,
Buková hora,
V bucích, and
U čtyř mostků) and deciduous forest (
Buková hora and
V bucích) as the elevation decreases. The slopes feature significant
glades and several hundred-meter-long slope clearings, especially on the southwestern slope (
Kamenná stráň and
Buková hora).
Geology Geologically, Dlouhé stráně belongs to the unit known as the and is composed of
metamorphic rocks, mainly
gneisses (
biotite,
muscovite,
chlorite,
garnet), , and
migmatites. During the excavation of rock tunnels, geologists also found
paragneisses with
amphibolite and
pegmatite inclusions in the mountain massif.
Waters The summit and its slopes lie southwest of this boundary, thus belonging to the Black Sea basin, into which waters flow from the
Danube's catchment area, including mountain streams from this part of the Hrubý Jeseník mountains (such as the nearby streams Jezerná, Studený potok (2), Kamenitý potok, and Borový potok). Several short, unnamed streams flow from the slopes as tributaries of the mentioned streams.
Waterfalls The following
waterfalls are on the slopes of the mountain: == Nature protection ==
