Trekking In Turkey: Long Distance Paths

Hi!

I'm planning on trying to do part of the Lycian way in the direction Fethiye-Antalya, between June 10 and July 1, the first 2 weeks with my Aunt, after that by myself. I'm aware it's going to be pretty hot during the day, so I guess we're going to play it by ear and see how we go distance-wise. We'll be trying to camp as much as possible, but probably eating as much non-camping food as possible (otherwise what's the point?). If anyone's interested in walking together at that time, drop me a line.

Also if anyone has experience of walking at that time of year, what kind of temperature range can be expected? It seems that at the highest points of the trail, around 1800m, the temperature could probably get down around ?20 degrees at night... I'm just wondering how much cold weather stuff to bring - I was planning a fairly light sleeping bag, 1 layer of thermals, one warmish jumper, and a waterproof jacket. Is that ridiculously underdressed?

Thanks!
