So, antelope canyon is not a US National Park. It is park of the Navajo tribal land. Antelope canyon lay just outside of Page, AZ (HWY 98 E -- toward CO). Antelope Canyon divided into upper and lower canyon. The upper canyon is where you'll find the famous corkscrew and candle light but filled with tourist while the lower canyon have less visitor. The formation is not quite compare the upper one but it has it uniqueness. I love both.
In order to visit these canyon, you need to go with a tour. There are many tour service in Page, AZ that offer tour for the upper antelope. Cost run around $25/person, tour last about 1.5 hrs.
There is no need to book tour weeks in advance. I usually pick up a visitor guide where they have discount coupons for these tour. To visit the lower antelope, one need to drive to the park itself, locate on the opposite road of upper. There, you need to pay a fee and there'll be a guide to take you in. If you want to tour on your own, bring a tripod and a camera, then you'll be on photography tour. Take your time and enjoy the magnificent scenery.
Beside Antelope canyon, surrounding Page, AZ are Horseshoe Bend national monument, Lake Powell and Glen canyon national recreation area. Horseshoe Bend located on 89-S, going toward Flagstaff,AZ, there is no admission fee to enter. Lake Powel locate justright outside of Page,AZ.
Lake Powell. The water is very clear. It's like oasis.
