If you’re looking for the complete route description, I’m afraid you’re out of luck. You’ll need to buy the Cicerone guidebook when it comes out – a small price to pay for peace of mind. But you can see an overview below.
My route is based on the existing ‘E4’ footpath – which has its own excellent website here (German only) – with detours to my favourite mountain summits and river gorges, and suggestions to avoid road walks and other boring bits.
There are 14 stages, each of which takes a day i.e. 5-8 hours of walking time. But it’s quite flexible. You can split the route at Tripoli (stage 7), to make two 7-day routes. You can add up to 6 days of detours, to bring it up to 20 days (or more, if you get lost). You can cut a couple of the less interesting days (stages 7 and 8). You can end up at the harbour town of Gythio (ferries to Crete), instead of Pantazi beach. You can even take the occasional taxi; it’s not a competition.
The bit about getting lost overnight was a joke, by the way. But you do need to book your accommodation in advance, especially as some guesthouses are liable to close.
