Episode 5

Rock royalty Ronnie Wood and his family visit Lord and Lady Bath for a look at his bronze sculpture in the Secret Garden. At Cheddar Gorge, cavers descend into 'The Frozen Deep' to measure what could be the largest cave chamber in the UK. In the Rhino enclosure, keepers work with a team of scientists to try to harvest the eggs from Lady Bath's favourite rhino in a bid to help save the Northern Grey Rhino from extinction.
