The weather in Yellowstone in January is freezing, so you must be prepared accordingly. If you are hiking or camping out in the park, you should have an extra layer of thick clothing that you can use if you get cold.

In most cases, fur suits well with the park’s climate conditions. Wear a pair of jeans made from fur-free materials if the weather allows. But, if it’s too cold, wear fur-lined jeans. Furs keep you warm and dry from the cold.

Wear thermal inners to keep your body insulated, and use neck scarves, lined gloves, and winter hats. Use clothes made of only woolen or fleece material.

For shoes, you should only wear snow boots or thermal boots. If you are going to hike, then keep warm hiking shoes.

If you want to spend the night watching the stars, you can stay at Under Canvas Yellowstone and enjoy the beauty of the night sky. You can also enjoy campfires, watch the wildlife, or check out the bars and restaurants in the park.

We can’t stress enough how important it is to wear super warm clothes at night. If you plan to sleep in the park, it is advisable to have extra layers of clothing since the temperatures can drop quickly. 

Staying outdoors for extended periods also increases your risk of hypothermia, so keep yourself covered from head to toe. 

In addition to thermal innerwear, go for clothes made of wool or fleece. Keep thick snow coats and down-filled jackets for layering up.

Use all the necessary winter accessories, including scarves, gloves, socks, and hats. You might want to cover your nose as well to prevent frostbite.
