Mammoth Cave National Park(猛犸洞国家公园) in America is a great park. And Mammoth Cave is the world’s longest cave system.

Last July, my husband and I took our six children to visit it. The park itself was free to enter. However, one had to buy tickets for cave tours. The Trog Tour was interesting. However, only children between th ages of 8 and 12 could take this tour. So my family took two differen tours in the morning. My three kids aged 8-11 took the Trog Tour. And the rest of us took the Historic Tour.   

In the afternoon, my husband and I took our children to take the New Entrance Tour. It was really cool.

We loved our visit to Mammoth Cave National Park. What a cool place! Next time we visit the park, we really want to take the Violet City Lantern Tour.
