Lake Bled, Slovenia

Lake Bled's emerald waters, island church, and medieval cliff castle compose a view so picture-perfect it looks like a screensaver come to life. Spanning 1.45 square kilometers, the lake features Bled Island at just 0.07 square kilometers, a tiny gem reached by traditional pletna boats. Cheaper than the typical rival European lake destination, a day trip averages €40 per person. Over 1.5 million visitors annually capture the iconic vista from the 11th-century castle, making it 20% more Instagram-tagged than #7 Salar de Uyuni during summer months.
