Stemnitsa, 26km northwest of Tripoli, is a striking village of stone houses and Byzantine churches. If you want to peek into any of the churches, ask around for the keys. There are several monasteries in the area, in the Lousios Gorge along the riverbank to/from the site of Ancient Gortys.
The starting (or finishing) point for the Menalon Trail, Stemnitsa is a good base for hikers. It provides a useful base for a hike along the Lousios Gorge, accessed by Ancient Gortys and passing by monasteries including Prodomos, and the New and Old Philosophou.
Stemnitsa is also known for its silver and gold craftsmanship; even today, there is a silversmith school here.
