Four celebs struggle to find their canal legs, but once they do, visits to local vineyards await.
On the second leg of the foursome's jaunt along the Kennet and Avon canal, the group must negotiate the 29 locks of the Cain Hill Flight.
The celebs conclude their narrow-boating odyssey with a trip down the Llangollen Canal. Nigel tries to escape when it is his turn to cook, Lorraine's sense of adventure tests the team to possible destruction, Simon tries to overcome his claustrophobia and Debbie faces a personal demon. Their journey ends at the stunning Pontyscyllte Aqueduct.
