I did hiking there in November 2014. My guide was Dado. The trip was excellent! The landscapes in autumn are so beautiful and the weather was really good (sunny). Dado is a very good guide, hiking with him is a very good time, spent in the mountains. He explains a lot, and tells everything you want to know about the mountains, the role of this are during the siege of Sarajevo and were you can still find some landmines. The trail to Lukomil is FREE of any landmines so you are totally safe, in addition Dado knows this mountains very good.
The visit in Lukomir village is once-in-a-lifetime - you will always remember it! You can talk with people living there and drink traditional bosnian coffee, that will keep you in condition to hike more! (it's really good and really strong! - but I recommend it!)
So it was very good time spent for me and I want to come back one day to do some other hiking, maybe this time in Montenegro!
