Accessibility is limited due to steep stairs and uneven passages inside the cave, so it is not recommended for wheelchairs. There is an alternative outdoor path that is flatter and allows partial viewing. Contact the visitor center at +359 54 800 123 for special assistance.
Near the cave, visit the Monument to 1300 Years of Bulgaria in Shumen, just a 15-minute drive away, or the Regional History Museum of Shumen for more cultural context. You can also explore the Madara Historical Park, a UNESCO site 20 km away. Use TripAdvisor for maps and reviews.
Wear comfortable shoes and a light jacket, as the temperature inside is cool (around 12°C) regardless of the weather outside.
