Those wanting to visit the Yellowstone National Park will now be required to make a reservation if visiting during peak season.
The National Park System made the announcement on their website stating that they are making the change in an effort to cut down on some of the congestion at the park while several visitor sites are under repair.

Peak season at the park is considered May 20 through Sept. 30 from 6am to 4pm.
Authorities are warning that you will not be able to enter the park without a reservation.
There is $35-per-car entrance fee and a non-refundable reservation fee.
