Yellowstone National Park reached a record number of visitors this summer and remains on track for its busiest year ever.

Nearly 2.3 million people visited Yellowstone in June, July, and August. This is a 5 percent increase from the previous summer high, set in 1999.

For the year, more than 2.6 million people have visited the park, marking the first eight months of 2009 the busiest January through August in the park’s history.

Park officials believe the large number of visitors this year is due to factors such as good weather, drop in gas prices, and the travelers’ ability to tailor a Yellowstone trip to their budgets.
