Peter arrives on the island of Kos; it's the third-largest island in the Dodecanese, and the second-most populous; apart from there being plenty of landmasses to explore, there are also loads of interesting people to chat to along the way.
Peter travels to Nysiros, a place known for its volcanic heart and quaint towns; things just move a touch slower as it lacks the infrastructure and resorts that draw in the masses.
Peter enjoys his time on Symi before he heads to one of the nearby islands, Alimia; abandoned 50 years ago, the little slice of paradise has some great stories that have sat under the radar for way too long.
Peter leaves the largest island in the group, Rhodes, and heads east to one of the smallest, Kastellorizo, in the farthest corner of Greece, sitting just off the coast of Turkey.
