Serving as a gateway to the Triglav National park is Lake Bled, a scenic body of water surrounded by the Julian Alps. The emerald green lake isn’t large, and it is possible to walk the perimeter in a single afternoon. What makes the destination so appealing is the small island in the middle of the lake, which is home to a 17th century church. You might also want to ride horses on the shores of the lake, rent a rowboat to explore the water or climb 15 minutes to reach Bled Castle, which dates back to the 17th century and boasts magnificent views over the lake below.
