【明報專訊】Since its establishment in 1872 as the first officially designated national park in the US, Yellowstone (黃石國家公園) has inspired the creation of hundreds of national parks around the world. Located in the northwestern corner of Wyoming (美國懷俄明州), the park is a paradise for wildlife and a geological wonderland. To experience the genuine Yellowstone, visitors should grab their backpacks and camping gear and immerse themselves in the surroundings. Exotic species are abundant in the area, and the 1,770 kilometres of trails offer all kinds of treasures for one to enjoy.
