JACKSON, Wyo. (AP) — Grand Teton National Park had its busiest September in the park's history by more than 50,000 visitors.

The Jackson Hole News and Guide reports that last month's visitation count totaled 475,000 people and jumped nearly 13 percent from the next busiest September, which was in 2010.

There were 422,000 visitors that year. September's visitation totals also surpassed those from September 2014 by 100,000, an increase of 28 percent. Teton park spokesman Andrew White says total visitation so far this year is already up about 8 percent from last year, when the park's all-time visitation record was set.

Yellowstone National Park has also already surpassed its visitation record ahead of the year's end.
