This is one of my favorite eco trails ever. It's certainly the most scenic, with tall trees, a flowing river, and a really cool cave. You can walk the entire trail in about an hour but you should really do it slowly so you can enjoy all the views. There are a few bridges to cross which give even more charm to the trail. You'll find picnic trails around, so if you come early and on a sunny day, definitely have a bite. Alternatively, you can buy grilled sausage (kuyfte, kebapche) with bread and baked beans, as well as refreshments from the little food truck outside. #hiking #bulgaria #nature
