Beli Iskar is a great eco trail if you like a long but fairly easy walk. The terrain is mostly flat and goes on for 5k in on direction. There are 25 bridges along the trail and the water is crystal clear. Honest, you'll find the freshest air around here which would rrally get your appetite going so prepare to have a picnic. There are tables and benches along the trail. Right towards the very end of it, there's a small hit with a roof in case it rains. This spot is perfect for any level of fitness, it's not hard, and it's a fantastic way to spend the day. If you're hungry and didn't bring food, you can drive down to the nearby restaurants in the village or by the ski lift some 15min away. #bulgaria #ecotrail #hiking
