The course starts inside a snowy forest with Beartic and Furret. After passing through the forest and some cliffs, the NEO-ONE reaches a massive field of snow with Swinub and Mamoswine. A Vivillon or Frosmoth can be located in an ice crack hidden in the area. After leaving this area, the NEO-ONE slides down some snow into an icy cave with Snorunt. After leaving the cave, the player can reach an area with several small ponds. Spheal and Alolan Vulpix can be found playing around the area. The course ends near an arch made out of ice. The course is mostly unchanged during the night, though some of the Pokémon are different.
Alternate routes
On research level 2 or 3, the player must take a picture of an Alolan Sandslash at the left side of the course. The Sandslash later reappears at the cliffs surrounding a Beartic and Cubchoo. After taking another photo of it, the Sandslash will dig through a wall of snow, allowing the player to enter the alternate route. There is a smaller forest, an Abomasnow, and some Crabominable in the route.
In the night variant, the player must enter the aforementioned alternate route. A Crabominable will then anger the Abomasnow, which causes it to use Blizzard. A Froslass will appear and after taking a photo of it, the player can access another alternate route that leads to an icy cave with Vanilluxe and ancient ruins. After that, the cave leads to a sea with icebergs, Avalugg and many Pokémon that were previously seen in the course. The course ends in an area near Aurorus. After completing this route at night, the player will be able to access it in the daytime.
Prior to the version 2.0 update, Shiver Snowfields was the course with the largest number of Pokémon, being 30. After the update, the course with the largest number of Pokémon became Florio Nature Park instead.
