Yes, you can do the trip on your own. I just did in the middle of May 2018, I also wrote a review about the trip on Tripadvisor: The Qadisha valley is a wonderful place. We went for a 25km hike in May - and had, weirdly enough, a lot of rain. But even though we were completely wet in the evening, it was completely worth it. We left from Bauhaus hotel - just outside of Bcharré, from where a small street (also a big one, but you should take the small one) goes down into the valley. The way is very well marked (I forgot which color though). Nonetheless, you see that the path is not frequently used, because sometimes the grass was as high as our knees, and apart from the marks on the trees and roadsides, there was, at moments, no visible path. The path down the valley is breathtaking, but quite steep. At a certain point there was a chain in the rocks, in case the rocks were wet. So, better not take this way with children. There is another path that leaves from Bcharré city center, which is apparently less beautiful, but easier. Once you arrive at the first monastery - after about an hour of hiking, the path gets very easy, and follows the riverbed, where there is a track - always well marked - for 4x4's. About every hour from then onwards, there is a different monastery along the road. At the river valley, the roads biforcate from time to time, so better have a map. We didn't find a detailed map on the spot, but I used the application maps.me, where all roads are very well indicated. About halfway, just before the Qannoubine monastery, there is a restaurant along the way, with decent lunch for a reasonable price. Drinking water can be refilled here. After a whole day of walking, we left the trail for a final, steep, climb of about 2 hours towards Ehden from where we hitchhiked back to Bcharré without any difficulties. There is also a bus passing to Bcharré - at least once an hour, but maybe more frequently than that as well. As I told in the beginning, the way is well marked, and until you arrive at the Qannoubine monastery, it is almost not possible to lose the way. Before Qannoubine, the way splits in two, but they both run parallel, and arrive at the restaurant just before Qannoubine. Afterwards though, there are various trails leaving the valley towards different villages on the hill top, so it is best to have a map with you, unless you don't mind which way to take and which monastery to see.
