If starting from Perithori follow a paved track west of the village that ends before the ruins of a WWII military camp. The segment from Dasoto joins here from the right. Turn left on the broad track ascending through forest. Pass a chapel with water (good camping spot) and saddle and continue downhill to emerge at the main road just outside Kato Vrontou.
Just a few tavernas.
Taxi or bus to Nevrokopi (summer only, three times a week, Tel: 25210-32734, http://www.kteldramas.gr). From there daily bus to Drama.
A couple of non-informative signs.
