• Stay on marked trails, since this is a national nature reserve and leaving them is not allowed
• Derelict missile base on the summit, reached by an asphalt road; the bunkers are crumbling and airsoft players use them at weekends
• Wildlife on the slopes, with over 600 butterfly species, praying mantises and the Saga pedo bush cricket, up to 7 cm long

Devínska Kobyla is the city's highest hill (514 m), a wooded limestone ridge with marked trails to Devín, Dúbravka and Karlova Ves. The E2 nature trail has five boards on its rare plants, wildlife and history.

On the summit sit the concrete silos and bunkers of an abandoned Cold War missile base, and an observation tower shaped like a praying mantis looks out over the Danube, the Morava and Austria.
