Rhodope mountains, one of the most beatiful places. Many years ago I spent 3 months there, on the Greek side, near the Bulgarian border. If you want to visit a non-touristic Greece, go east of Kavala, to oriental Xanthi, Komotini, Soufli, national park of Nestos river for kayak and bird watching. Old Byzantian bridges in the middle of forest, Thracian sancuaries….The Bulgarian side is also beatifull.
Yeah, keep in mind they will send you a used up piece of junk, so in that case you will have to be awarded with a fee to manage it.
