The length that fits the country
Five days is long enough to reach both the coast and the mountains without spending every morning packing, and short enough to take as leave without negotiation.
Coast and mountains in one trip
The whole country is 340km end to end. In five days you can stand on an Ionian beach and inside an Ottoman castle, with a day in between to do neither.
Arranged end to end
Beds, transport and guiding are booked before you land, so the five days go on the country rather than on logistics. What each price covers is on its own listing.
Long enough to stop
Five days holds one unplanned afternoon without wrecking the itinerary — the market, the second coffee, the road someone recommends over dinner.
