>>58011032The main path of Route 119 goes in an S-shaped curve, crossing the river multiple times. The landscape switches multiple times, from the vast long grass field, to the rocky riverbank to the forest clearing near the weather institute. There are also multiple optional paths branching off, all accessible with different means (surf, acro bike, waterfall).
The Sinnoh one below it is a bit more linear, but still has a unique enough shape that it doesn't feel like a straight line without being a maze, and also shows a variety of landscapes: a garden to the north, followed by a forest clearing, some hills, bridges, marshland.
