Plan your trips now! The National Park Service has announced the 2015 days of free admission to the few parks that charge admission. One of the best things I ever did was get an Annual Pass for National Parks in 2013. It helped that we visited 5 parks in one road trip, but we managed to visit a few more and it was great waving the pass to get in to the parks.
Here are the dates:
2014
November 11 Veterans Day
2015
January 19 – Martin Luther King Jr. Day
February 14-16 – Presidents Day weekend
April 18-19 – opening weekend of National Park Week
August 25 – National Park Service Birthday
September 26 – National Public Lands Day
November 11 – Veterans Day
