JACKSON, Wyo. (AP) — The National Park Service is considering raising entrance fees to Yellowstone and Grand Teton national parks by $5.

Vehicles entering the parks now are charged $25 for a seven-day pass good for both parks.

The Park Service is looking at fee increases at other parks around the country as well.

Yellowstone spokesman Al Nash says a $5 increase in the rate per vehicle would likely add more than $1 million annually to Yellowstone's coffers.

Nash says the world's first national park typically collects about $8 million at its gates.

Yellowstone and Grand Teton officials have until mid-February to submit proposals to increase their fees. The proposals will be received and have to be approved by the Park Service's regional office.
