Dymník is a modest but fascinating forested hill in the Šluknov Hills, just 2 km southwest of Rumburk. Standing at only 517 metres, it hides a volcanic history 30 million years in the making and rewards visitors with a lookout tower offering sweeping views.

At the foot of the hill rise basalt rock formations up to 20 metres tall, evidence of Tertiary volcanic activity in the region. The summit itself is essentially a volcanic dyke that pushed through much older granodiorite rock, leaving behind rocky outcrops with a distinctive, partly slab-like structure. Less than 200 metres from the top grow two protected beech trees known as the Beeches of Dymník. The surrounding forest feels especially atmospheric in autumn and spring, and on clear days the view from the tower stretches remarkably far.

• From Rumburk — yellow trail, approx. 30-40 minutes, easy route, accessible by road
• From the parking lot with a restaurant below the hill — remaining 300 m via blue trail

• Entry to the lookout tower requires a ticket
• The tower is 15 m tall with 79 steps
• Since October 2010, the Dymník Nature Trail leads here from Rumburk

The name Dymník comes from medieval signal fires once lit on the summit — literally the 'smoker' hill. The tower, called August's Tower and built in 1896 by a local entrepreneur, offers views on clear days as far as the Krkonoše Mountains, Ještěd, Milešovka, and even the Saxon hills of Bieleboh and Czorneboh.
