POWELL, Wyo. (AP) — This winter snowmobilers again will be allowed to enter Yellowstone National Park without a paid guide.

However, snowmobilers on their own have to meet various requirements set up by the National Park Service.

Visitors can drive their own snowmobiles into Yellowstone only if their sleds meet the detailed "Best Available Technology" requirements. In addition, they must first take an online certification course and meet other requirements.

Also, only one non-commercial group of up to five snowmobiles is allowed to enter a given entrance each day.

Still, winter-related business owners tell the Powell Tribune that there has been a lot of interest in the new non-guided rules and that they are renting out snowmobiles again.
