Of all the Eevee evolutions available to you in any mainline Pokémon game, we’ve always been very fond of Glaceon. Ice-type Pokémon always seem to be pretty limited in supply, so we like the ability to take our cute Eevee and turn her into a cool and stylish Glaceon. In Pokémon Scarlet and Violet this is possible, but requires a bit of luck. How to evolve Eevee into Glaceon in Pokémon Scarlet and Violet.

How to make Eevee evolve into Glaceon in Pokémon Scarlet and Violet
As with most of the other Eevee evolutions in Pokémon Scarlet and Violet, the process to get a Glaceon only requires the correct Evolution Stone in hand, in this case an Ice Stone. Unfortunately, unlike some of the other Evolution Stones in the game, Ice Stones are never for sale in the Delibird Presents shop, so you can’t just drop some cash on one when you’re ready to level up your Eevee. Instead, you must travel to the snow-capped Glaseado Mountain in the northern part of Paldea.
There is at least one spot where an ice stone spawns normally. Make your way to the Glaseado Mountain Pokémon Center and head southwest to find a cliff. In the middle of that cliff is an Ice Stone that you can use on your Eevee or any other eligible Pokemon.
If you evolved your Glaceon from Eevee, you’ll have a Pokemon that will be very strong against Dragon-type Pokemon and also super effective against Flying, Grass, and Ground-type Pokemon. Just remember that it’s also weak against Combat, Fire, Rock, and Steel attacks.
