Kents Cavern is a cave system in Torquay, with a long archaeological story. Visitors walk through a labyrinth of caverns surrounded by rocks around 400 million years old, with stalagmites and stalactites along the way. The caves were once used by ancient humans for shelter, fire-making, tool-making and hunting Ice Age animals, and the tour includes a moment of total darkness.

Tip: Book online to secure your preferred tour time, and arrive at least 15 minutes before it starts. Solo visitors should call ahead, as a tour needs at least two people.

Tip: Pre-book your tickets online, as entry can't be guaranteed without a booking, especially at weekends and in school holidays.

Exeter Cathedral has stood at the heart of Devon for nearly a thousand years.

Tip: Head for the Treasures Exhibition tour or a guided floor tour, both included in standard admission, though floor tours are subject to availability.
