Turkey now has two long distance trekking routes: The Lycian Way, opened in 1999, and The St Paul Trail, opened in 2004.
Both trails are about 500km long. Kate Clow with Terry Richardson (of Rough Guide) researched designed and implemented both trails. Kate and Terry produced the guide books and maps to the two trails, assisted by George Zsiga, who drew the maps and Ueli Aellig and others who took GPS readings.
The Lycian Way is a 509 km way-marked footpath around the coast of Lycia in southern Turkey, from Fethiye to Antalya. The route is graded medium to hard; it is not level walking, but has many ascents and descents as it approaches and veers away from the sea. It is easier at the start near Fethiye and gets more difficult as it progresses.
It is recommended that you walk the route in spring or autumn; February-May or September-November; summer in Lycia is hot, although you could walk short, shady sections. The route is mainly over footpaths and mule trails; it is mostly over limestone and often hard and stony underfoot.
The St. Paul Trail is a way-marked footpath from Perge, 10 km East of Antalya, to Yalvaç, NE of Lake Eğirdir. There is a second branch starting at Aspendos, 40km E of Antalya and joining the first route at the Roman site of Adada. The route totals about 500km.
This project partly follows the route walked by St Paul on his first missionary journey in Asia Minor. It's a wilder route than the Lycian Way, starting at sea level and climbing up to 2200m, with two optional peaks at around 2800m. At the moment there are no signposts on the route (they are looking for a sponsor) but the way-marking is complete.
A few years ago, we had a day to spare in Kaş and walked a
very small part of the Lycian Trail - well you're probably younger than us,
gokmen1313! From Kaş we walked to the rocky bay of Çoban Plajı overlooking the Greek island of Kastellorizo and then on to some crumbling cottages at Ufak Dere. A lovely walk, but enough for us!
