The streams forded by this path wind past copses and grassy patches in a serene and soothing manner. The Lost Tower is where Pokémon are laid to rest when their lives come to an end.
Route 209 is a fairly large route that curves around to make a reverse L-shape. It starts from the west, from Hearthome City, where the route makes its way east. There is a large patch of tall grass just north here, just off the path. Back on the path, the route heads east, making its way over to a series of bridges going over a running stream, in which the player must cross in order to reach to the other side. There will be several Trainers to battle on the way, and by going onto a bridge that travels north, then west, the player can find some loamy, soft soil to plant four Berries.
Making its way east again, the player will find the Hallowed Tower near a running stream. If the player travels north-west, they will reach a Honey Tree, which the player can slather honey on to attract wild Pokémon.
After that, the route heads directly north, with a few patches of grass around the place, some soft soil to plant two Berries, and several Trainers to battle. Further up is a steep slope, bike obstacle, for those who want to avoid the tall grass. The Lost Tower is just east from this point. It is a tall tower where dead Pokémon rest. Many Trainers come here to visit their Pokémon that have passed away. Just below the Lost Tower is a tree that can be cut down to obtain an item, TM47 (Steel Wing). On the north-west side of the route is a small area that contains the item Calcium, that can only be accessed to with a bike in fourth gear. Directly to the north of the route is the entrance to Solaceon Town.

An arrangement of this route’s music (Route 209) plays during the end credits of Pokémon Legends: Arceus.
Similarly, motifs from this route's music are featured in the first of the two of the themes that play during midday in the Cobalt Coastlands in Pokémon Legends: Arceus, "Cobalt Coastlands 1-1", as well as featuring more motifs when replaced with "Cobalt Coastlands 1-2" upon "Mission 10: The Lordless Island" being completed.
The route is a part of a three-part straight line consisting of Route 210, Solaceon Town, and Route 209. This may be to make it easier for the player to hatch an Egg received from the Day Care.
