Loučná (956 m a.s.l.) is the highest peak in the eastern Ore Mountains and the loftiest point in the Most district of the Czech Republic. It is a quiet, atmospheric summit with granite outcrops, a military watchtower and a forest slowly coming back to life after decades of industrial pollution damage.

The summit forms a broad, relatively flat plateau covered in birches and beeches. The spruce forest that was devastated by emissions in the 1980s is gradually regenerating, giving the landscape a raw, recovering feel that is quite moving in its own way. Two granite rock formations crown the top: the lower, southern rock hosts two wooden crosses and is the endpoint of the marked hiking trail; the higher, northern rock is the true summit of Loučná, located within the Flájská obora game reserve. On top of it sits a triangulation point and a steel military observation tower dating from the 1950s, once used by the Czechoslovak Army. Foundations of other military structures and a concrete access road are still visible nearby. On a clear day the surrounding summits are easy to spot — V Oboře (888 m) to the north, Studenec (878 m) to the west, Střelná (868 m) to the south and Vlčí hora (890 m) with its lookout tower to the east.

• Litvínov / Meziboří — blue-marked trail with a signed branch to Loučná, moderate difficulty. The main trail runs from Litvínov through Meziboří toward Dlouhá Louka; the side path leads to the southern rock formation at the summit.

• The higher northern summit lies inside the Flájská obora enclosed game reserve — access may be restricted.
• The official hiking trail ends at the southern rock with the wooden crosses, not at the absolute highest point.
• Loučná was the finish line of the Loučná 956 cycling and running race, held annually from 2000 to 2012.

That steel observation tower near the top is a genuine Cold War relic — a reminder that this quiet forested hill once served as a military vantage point for the Czechoslovak Army in the 1950s.
