Solitas has a cold climate, which makes it mostly inhospitable to both Humans and Grimm. It's described as easy to get lost in, especially in its tundras. In certain areas, forests such as the Snowbound Forest are capable of growing. Wildlife amongst in Solitas is shown to include prize deer and penguins.
Auroras, or polar lights, are often seen in the night sky of Solitas.
Over time, the Creatures of Grimm grew to adapt to the cold of Solitas, now said to be the strongest species of Grimm. However, the Grimm adapted at a supernaturally fast rate, leading many to wonder the cause of this change. Grimm that adapted to this climate include the Megoliath and Sabyr, amongst others.
- Solitas is a Latin word for "loneliness" or "solitude".
