11. Cities: Skylines Snowfall DLC

These you should already have if you followed the main city guide:

Here's A Tram

Have one tram line active

I Love Trams!

Have 10 tram lines active

Speed Up!

Boost 100km of streets with Road maintenance service

And just building a sauna in your city gets you:

Are They Naked In There?

Have a Sauna in the city

1 guide

Unfortunately the last two will require making a new city. It doesn't need to be fabulous or special, but it does need to be a map from this DLC (I used Snowy Coast). Also make sure you have dynamic weather on.

Here is the city I ended up with:

The only truly important things are snow dumps, though I would recommend advancing far enough to unlock incinerators, so you don't have to worry about garbage as much. Also bear in mind that on snowfall maps you need to provide heat to your citizens. That can be through electricity, but they will consume probably two to three times their normal usage when it gets really cold. You can also build heating plants to generate heat locally, but you will need to upgrade your pipes to ones that can carry heat as well. Once you are all set, you can add in a "snow farm" if you want to speed things up. Just make a bunch of 2 lane roads running down to the bottom of the peninsula, and connect the ends. Make them as close as you can to each other (2 cells of space between them), to pack as many as you can in that space. If you do that you will also need some extra snow dumps (I had two in my base city and two more for the snow farm). Then just let it idle until you get the achievement (shouldn't take more then an hour or two of idling at most, even without the snow farm).
