The petroglyphs are a short hike from the visitors center. The overall trail is about a mile long and allows up close access to the petroglyphs.
The sight has a small campground and an even smaller visitor's center. There is not much reason to stop at the visitor's center other than to pay the admission fee and get free water.
Here you will have to do a bit of climbing and walking, so bring water, a hat, sunscreen, and comfortable shoes --- and a camera! There are over 21,000 petroglyohs, or rock drawings/carvings here. Once you begin seeing them, you will see them everywhere you look. It is awesome! Well worth the $2.00 per vehicle entrance fee.
As with any of this country, you will need to keep your eyes open for snakes. Avoid stepping, or sticking your hands anywhere you can't see. Be especially watchful in shady spots. There's not much shade here, so if there is shade under a bush, a rock, or anything else, it is going to be a prime spot for finding one of these pesky biting critters.
Miscellaneous: Dont forget your hat, sunglasses, sun block, lip balm and your water bottle. If you have a fancy camera, watch out for your lens, it can get dusty at times.
Right at the turn for the Petroglyph site, there is a nice store called The Indigo Lizard. They sell a lot of nice gifts at moderate prices, it is worth checking it out.
Favorite thing: Here is the same image as teh previous one, except it's in color. Camera with a zoom lens is highly recommended! ;)
Favorite thing: This is one of the easily visible petroglyphs found in this area. Note the geometric designs in its body.
