The longest trolleybus line in the world
Russian-language article (translation in progress).
It's not the fastest way to do the journey - it takes 2 hours - but for the many who use it that's not the point.
The route takes you through the Yaila mountains across the Angarskiy Pass, reaching 752m (nearly 2,500 feet) at its highest point, and then drops down to Alushta on the coast. For the 41 km from Alushta to Yalta, the road snakes along above the sea, providing breathtaking views. The last thing you want to do is rush this route.
It also happens to be the cheapest way to do the journey - £1 ($1,5) is not bad for a 54 mile trip.
