Don’t Miss National Park Week

National Park Week 2011 will be held from April 16 to 24. During this week, all parks that charge entrance fees will waive them. The week begins with a day (April 16) dedicated to volunteerism. The penultimate day of the week, April 23, is Junior Ranger Day. Parks around the country will hold events during National Park Week, the theme of which is Healthy Parks, Healthy People. For example, on Sunday, April 17, Valley Forge National Historical Park (Pa.) will hold the sixth annual Valley Forge Revolutionary Five-Mile Run, accompanied by a one-mile youth fun run. Sagamore Hill National Historic Site (N.Y.), home of Theodore Roosevelt, will host its first U.S. naturalization ceremony on Monday, April 18 for 50 new citizens. At Mammoth Cave National Park (Ky.), free tours of Mammoth Passage will be offered throughout National Park Week. April 16 is a back country trail workday at Mammoth Cave, and volunteers are needed, while on Junior Ranger Day, the park will offer nature hikes and special programs (on subjects including art, music, and outdoor skills) for families and young children.
