The 2021 holiday event in Pokémon Go gives you plenty of chances to catch Pokémon that aren't generally available during most of the year. The cold brought them out and gave the coaches a much better chance of finding them. One such featured Pokémon includes Cryogonal. Here's how to catch one before the holiday event ends.
Although Cryogonal has a couple of areas that can be found during the 2021 holiday event, it still has a rare chance of appearing either way. Of the featured Pokémon that appear in the wild, you can find it while walking, but it will have far fewer chances than most others. We recommend using incense on your trainer, going to a park or other area with multiple Pokéstops, and using some lures. Walk back and forth between them and hopefully it will appear. It does not have a glossy shape.
The other way to encounter a Cryogonal is through a specific field research task. You will need to have achieved the task to win a level three or higher raid. Once you've done that, you'll have a guaranteed encounter with a Cryogonal, but getting the activity itself might take a bit of pokéstop rotation.
Either way, getting a Cryogonal may take some time. If you've got the field research business, we highly recommend you do so, but until then you may be better off just walking around and catching whatever you come across.
