Dear Vanya.
We can reach the canyon by car. Then we can Park the car and take the bus to travel around the canyon.
Buses are very cheap and make many stops on the way,so you can easily get off the bus to take the photo from your ad, then take the bus.
if you want to see the canyon at night we can take the plane and fly over the canyon hour. Raising is quite expensive but so it is beautiful !
crossing the canyon, it takes time, we can descend into the canyon to the river and then up.
remember that the canyon is really deep why --- two kilometers down and up.
so we should wear comfortable shoes and we should also have hats and jackets for protect us from the sun. we should have enough drinking water with you because it's very hot  in the canyon.
the food is not so important, there are many cafes around, so we can easy to find something to eat. write what you think about this plan.best wishes,Jenny.
