+Monument Valley Notes of 2008: The entrance is $5 per person. You cannot use the national park pass. You have to remain in the car most of the time and simply drive around a loop. The road can be very bad after rains. Popular picture spots are the visitor center (view of the buttes), Three Sisters, Totem Pole. Extremely dusty.
++Canyon de Chelly Notes of 2008: There is a campground right at the beginning of the two rims ($14). The south rim has the best attractions. The only hike you can do on your own is the White House trail, a steep but short trail that takes you to the floor of the canyon in 30 minutes (but then you have to hike back up which may take you twice as much). You cannot enter the ruins but you get close enough. There are many other viewpoints before and after the White House trailhead. It is worth checking out all of them but the very last one, the Spider Rock is everybody's favorite, probably the most impressive view of the canyon. The north rim has one lookout that is worth checking out: Mummy Cave overlook. You can exit the area from the north rim, and this might be ideal if you are headed east towards Four Corners. If you are coming from or going to Kayenta (Monument Valley, Grand Canyon), then it is faster to retrace your steps to Chinle and take 191 and then 59 to 160.
