Hiking trails from Diafani village are waymarked with red or blue markers or stone cairns. The most popular route heads inland, straight up the valley to Olymbos. That takes around two hours – though inevitably some prefer to catch a bus uphill and walk back down. Alternatively, a 50-minute track leads 4km north along the coast, through the pines, to Vananda Beach, which has a seasonal taverna.
A more strenuous three-hour walk takes you 11km northwest to the Hellenistic site of Vroukounda, passing the agricultural village of Avlona along the way. There are no facilities, so carry food and water with you.
Anyone planning serious walking should get hold of the 1:60,000 Karpathos-Kasos map, published by Terrain Maps (www.terrainmaps.gr) and available in Pigadia. For advice on current conditions, call in at the Environment Management Office on Diafani's seafront before you set off.
