This challenge is one of the last of Fortnite's 2019 Winterfest! You'll have to to visit three notable places directly related to the Christmas and New Year festivities: the Workshop, Crackshot's Cabin, and Mr. Polar's Artisanal Ice.
Map
The Workshop
The factory is on the edge of Weeping Woods, and slightly south of Holly Hedges. It's normally a sawmill, which has been reassigned with the Christmas holidays.
The Crackshot's Cabin
This house is Crackshot's home, the wooden puppet who welcomes you every day in the lobby of the Winter Lodge to discover your daily gift. This building is a remarkable spawn because it houses a fir tree lined with chests!
Mr. Polar's Artisanal Ice
The last notable place to visit for this challenge is the ice factory which is located in the large east hangar at Dirty Docks. It's an interesting spawn given the dozen or so coolers it contains. There you will find fish in large quantities, and very often a Snowball Launcher!
We recommend the Team Rumble mode to achieve this challenge, especially during the week following its release. It'll reduce your chances of running into warring enemies as soon as you land.
