To celebrate of the 100th birthday of the National Park Service, visitors will be offered free entry to national parks across the USA next week.

From the 16th to the 24 April, admission fees will be waived in all 59 parks, with a range of special activities also planned around National Junior Ranger Day on the 16th. There’s never been a better excuse to see the spring blossom in Yosemite, track crocodiles in the Everglades or hike near a smoking caldera in Hawaii Volcanoes National Park.
