Tunnel Of Love, Ukraine
The Tunnel of Love isn't very long, but this three to five kilometer stretch of industrial railway attracts tourists year round because of its unique vegetation. The tunnel formed over many years when trees grew around the train route forming natural arches with their branches. The railway links Klvean, Ukraine to the small city of Orzhiv.
The Tunnel of Love's patented green arches don't only look gorgeous in the summer. When autumn rolls around, the tunnel turns vibrant shades of yellow and orange. Though the railway is active, this Pinterest-perfect spot is a favorite for couples (if you couldn't tell by the name).
