To commemorate the centennial, the National Park Service is offering 16 opportunities for free entrance to parks across the country in 2016. The remaining dates are Aug. 25 to 28 (for the National Park Service's birthday), Sept. 24 (National Public Lands Day), and Nov. 11 (Veterans Day). It's a savings for visitors to the 127 sites that normally charge entrance fees.
Not only does piling everyone into one car save on gas, it also saves on entrance fees. Most national parks charge per vehicle, rather than per person, which can make a tight squeeze worth it. Once inside a large park, visitors can often leave their cars and take free shuttles for more savings on fuel. Although some parks have gas stations within park limits, prices tend to be higher than in town.
