With so many archaeological sites in Crete it can be difficult to choose the ones to visit during a short visit.
Tripitos is a small Hellenistic settlement just outside Sitia atop a low hill which provides spectacular views of the bays below. There is a sign on the main road pointing to it, and once you turn the road is very narrow and steep.
It seems like an abandoned site, with no ammenities or information on the site. While it seems like it was a healthy town in antiquity, and given the wealth of archaeological sites in Crete, Tripitos is on the itinerary of the most hard-core archaeology travelers.
