Oslo to Bergen by train: sit left

Much more beautiful ways when sitting on left if going from Oslo to Bergen via train: particularly beautiful views between Finse and Myrdal.

Èze: climb hills (towards the fort) rather than go to cactus garden

The title says it all: you will get beautiful views and a lovely, not much difficult hike as bonus if you climb the hills on the other side of the highway at the village of Èze near Nice. There won't be any further need to pay some astronomical price to get into a cactus garden.

That said, the village of St Paul de Vence is a much more charming village, even though also very touristy and rich: it's not a museum, unlike Èze.
