Nation­al Park Week 2011 kicks off tomor­row. From April 16th to April 24th, admis­sion to all 394 U.S. nation­al parks will be free! Their theme for this year is Healthy Peo­ple, Health Parks, designed to show the con­nec­tion between a healthy lifestyle and a health envi­ron­ment and how nation­al parks play a role.

Dur­ing the week, park part­ners will offer dis­counts on food, lodg­ing, tours and sou­venirs and com­mu­ni­ties near the nation­al parks are offer­ing up deals as well.
