In the final episode of the series, Paul embarks on his most difficult island Grand Tour to date. Every destination has been long abandoned by people, there are no ferries, no piers or proper landings at these islands making it quite a challenge to get there. Paul's journey sees him travel to the once-inhabited island of Heisgeir, sail around the gannet city of Sula Sgeir and endure rough seas to finally make landfall on the extraordinarily remote island of North Rona.
