Is Katla volcano dangerous?

Katla is one of Iceland's most powerful volcanoes and is overdue for an eruption based on historical patterns. An eruption could cause massive glacial floods (jökulhlaups) that would devastate areas south of the glacier. Monitoring systems are in place.

Are there ice caves in Mýrdalsjökull?

Yes, Kötlujökull (an outlet of Mýrdalsjökull) has ice caves that are accessible on guided tours, primarily during winter months. The Katla Ice Cave is one of the most popular.
