To reach Angelope Canyon, leave Page southeast via Coppermine Road to AZ98 in the direction of Kaibeto towards the power plant. The road to Lower Antelope Canyon is on your right.
If you want to save some money, it is best to drive to Lower Antelope Canyon and don't take the tours from Page. The Indian guides are excellent and by all means take their advice on your camera settings. Visit in early am or later in the afternoon for the best color. Do not attempt to go if rain is predicted as 11 people drowned here in a flash flood when they failed to heed the warnings of their guide.
Lower Antelope Canyon is just outside of Page, Utah and is about one quarter of a mile long. It is much longer than the more famous Upper Antelope Canyon
