Ayíou Stefánou (Tues– Sun: summer 9am–2pm & 3.30–6pm; winter 9am–1pm & 3–5pm), the last, easternmost monastery, is fifteen minutes' walk beyond Ayías Triádhos (no path short-cuts), appearing suddenly at a bend in the road. It's occupied by nuns keen to peddle trinkets, but the buildings – bombed during World War II and then raided during the civil war – are disappointing: the obvious one to miss if you're short of time. That said, the fifteenth-century refectory contains an apsidal fresco of the Virgin, beyond the museum graced by a fine Epitáfios (Good Friday bier) covering embroidered in gold thread. The trail towards Kalambáka from Ayíou Stefánou is disused and dangerous – return to Ayías Triádhos to use the descending path described above.
