Route 20 (Japanese: ２０番道路Route 20) is a route in eastern Kalos, connecting Snowbelle City and the Pokémon Village. The route is also known as Winding Woods (Japanese: 迷いの森Bewildering Woods).
Located in the woods on this route is a Moss Rock, which will allow players to evolve their Eevee into Leafeon.
Route 20 is located inside of a dense forest, twisting and turning to avoid trees. Many paths inside the forest lead to unexpected directions and dead ends, some even leading to different places depending on the directions taken, similar to the Lost Cave in the Sevii Islands. Due to the trees preventing most of the sunlight from reaching the forest floor, some nocturnal Pokémon like Noctowl can be found here. Near the Pokémon Village entrance, the path becomes partially clear of grass, allowing the player to locate the village easier.
Route 20 was the main setting of Seeing the Forest for the Trees!, where Ash befriended some of the wild Pokémon living in the forest and remembered his early days before becoming a Pokémon Trainer. After Ash and Greninja saved a group of Spewpa from freezing in a blizzard, they made amends and Ash recovered from his depression. In the process, they also perfected Greninja's Ash-Greninja form.
After his Flabébé evolved, Trevor gained the confidence to take on Aliana as well, thus allowing Y to get to X and Blue, both of whom had already reached the Pokémon Village. Bryony, Mable and Celosia were eventually defeated, with Aliana being forced to surrender when faced with Tierno, Trevor and Shauna. The trio then witnessed Xerneas and Yveltal reverting to their dormant forms.
This is the only location that is both a route and a forest.
