How this itinerary was computed
Assembly rule in Istanbul: the 22 attractions within the 40 km radius are ranked by documented notability on Wikidata (how many languages carry an article about the place) and grouped by a greedy algorithm: each day opens at the most famous one still outside the itinerary (Hagia Sophia for day 1 in Istanbul) and picks up, one by one, the nearest to the last stop, up to 4 per day. The 9 tabled hops add up to 22.5 km, always in straight lines (haversine formula): street routes run longer. The best season to visit Istanbul is not here because it cannot be computed from these sources, and this site does not make up guidebook opinions.
