【题目】 Known for its complicated, seemingly wavelike sandstone walls and the rays of sunlight that shine into them, Arizona's Antelope Canyon（羚羊峡谷）is an everlasting attraction for tourists. It's a slot canyon, meaning it formed from water carving it out over millions of years. It sits about 3, 700 feet above sea level and takes its name from the antelope that once lived in it.
The canyon forms part of Lake Powell Navajo Tribal Park in the Navajo Nation. The Navajo Nation limits visits to either the Upper or Lower Antelope Canyon to two hours and requires all visitors to be led by authorized guides. If you're planning a trip and need help deciding which area to visit, keep these recommendations in mind.
When: Tours are available twice a day during the week year-round, though exact times vary by season；tours are not available on weekends or major holidays.
Cost: Tour companies 5 fees vary, but tickets, including entrance to the park, generally start at around $ 60 for 90-minute tours of Upper Antelope Canyon. Tours of Lower Antelope Canyon tend to be around an hour and generally cost around $ 40 per adult and $ 20 for children.
Must-know tip: Most of Arizona does not follow daylight saving time, though the Navajo Nation, where Antelope Canyon is located, does. Check with your tour operator to confirm the precise time of your tour.
Antelope Canyon hosts tons of visitors and, in order to protect the canyon walls from damage, no bags of any kind are permitted in either the Upper or Lower section. Also keep in mind that while most tour companies welcome small children, not all of them will.
