Chaco Culture National Historical Park

Mesa Verde, in Colorado is one of the best preserved native Indian ruins in the United States. With two entrances,the northern one is paved I believe (I went to the south, with 20 miles of dirt road, but in good condition). Once inside the park there is a good quality 9 mile road through the Indian Villages (special reference to Pueblo Bonito). There is an easy walk that takes you through the top of the mountains to Pueblo Bonito from above. The road takes more than two hours and the views are breathtaking (we had to ask permission at the tourist centre before doing this though)
