Ralsko Hill, Nature reserve in Noviny pod Ralskem, Czech Republic.

Ralsko Hill is a basalt cone mountain rising to 698 meters in the Liberec Region, characterized by steep slopes and natural rock outcrops. The summit holds the remains of a medieval fortification that once dominated the landscape.

The summit area was first protected in 1933; the reserve was re-declared by ministerial decree on 26 September 1967 on 18.15 ha, registered under no. 360 in the cadastres of Noviny pod Ralskem and Hvězdov, and confirmed on 21 December 1987. After 1968 Soviet soldiers damaged it through unauthorised aggregate extraction and left many Cyrillic inscriptions. It now covers 22.32 ha between 575 and 698 m.

Medieval castle ruins at the summit reveal how fortifications were constructed and used to defend the region. Visitors can see the defensive design reflected in the remaining walls and tower foundations.

Marked hiking trails lead to the summit and are accessible for visitors with moderate fitness levels. The nearby town provides parking and visitor information to help you plan your visit.

The mountain has volcanic origins and hosts specialized plant species adapted to the basalt substrate, which are rarely found elsewhere in the region. These botanical features make it noteworthy for nature enthusiasts.
