Muswell Mole is a cave tour guide with an unexpected Australian accent and an impressive knowledge of stalactites. He learnt his craft Down Under, navigating glow-worm tunnels with nothing but a torch – and sheer charm.

Now, he runs subterranean tours across London (he lives for an abandoned tube station).

Join him on one of his tours, but don’t be startled by the abrupt stops or spontaneous facts – Muswell’s got a heart as warm as his headlamp, and a nose for hidden wonder!
