     Five million people visit Grand Canyon in the US every year. For the purpose of helping project Grand

Canyon for your fellow visitors and future generations, please follow the guidelines below. 

Camping 

     To project the park, camping is allowed only within permitted campgrounds. Permits are required for

overnight camping at the North Rim. Advance booking can be received by mail. Please write: Information

Center, P.O. Box 129, Grand Canyon, AZ 86023

Fires

     Because of the extreme fire danger, campfires are not allowed except at Mather and Desert View

campgrounds. Collection of firewood is not allowed either.

Hiking (远足)

     Please stay on permitted paths. Otherwise you may destroy desert plants. Pack out what you pack in,

so you leave no signs of your visit. It is important to keep in mind that you are in a national park where

wildlife exists.

Weather

     The weather at Grand Canyon can change very quickly. With so much rock, lightning (闪电) causes

a particular danger during sudden summer storms. These storms also frequently bring floods inside valleys,

a danger to hikers. Watch the skies and check daily weather reports.

Wildlife

     Do not feed park wildlife. There have been a few cases at Grand Canyon National Park where deer (鹿)

were purposely shot because they are plastic bags that left them sick and weak. Hungry deer can be danger

and have kicked and bitten visitors at Grand Canyon. Some other animals will also beg and bite. For your

own safety and the well-being of the animals, please do not feed wildlife, no matter how gentle they may

appear.
