This info was just released today. There were some folks who seemed interested in it, so I thought I'd post it here.
JACKSON, Wyo. (AP) -- Yellowstone National Park's 2014 opening and closing dates generally are the same as last year's - with some earlier fall closures due to park construction.
The Jackson Hole News & Guide reported Thursday ( http://bit.ly/1hWtJph
) that Yellowstone's South Gate, which provides access from Jackson Hole, will open May 9.
The East Gate, with access from Cody, opens May 2. The West Yellowstone, Mont., entrance opens April 18.
This fall, Jackson Hole visitors will have to take an indirect route to Old Faithful after Sept. 2. The Mammoth Hot Springs-to-Norris road will shut down completely between Sept. 14 and Sept. 30.
Yellowstone's winter season will close in phases beginning Friday, when the East Gate will close until spring. Skiers, cyclists and hikers are exempt from the winter closures.
