Kaylaka (Bulgarian: Кайлъка [kɐjˈɫɤkɐ]) is a large park and protected area south of Pleven, Bulgaria, situated in a Karst valley.
The park is spread over 10 km2 and is surrounded by sheer cliffs that suggest favourable conditions for rock climbing.
The ruins of the Roman fortress of Storgosia are located in Kaylaka, as well as ponds and reservoirs with boats and pedalos, a swimming pool, hotels, cafés, restaurants, discothèques and playgrounds.
The place is suitable for different outdoor activities including jogging, cycling, kayaking, rock climbing, fishing, and many others.
Prehistoric animals and creatures lived there millions of years ago, and fossils of ancient aquatic organisms can still be seen in most limestone cliffs.
