The Mesa Verde National Park is just 50 miles from Durango southwest on Highway 160. It was a very pretty drive. The roads in the park would be perfect bike rides and there were plenty of bikes in the park.
We took a 2-1/2 mile hike along the petroglyph trail. Some people walked right past the petroglyphs while concentrating on the trail - not us. On the return trail along the top of the mesa we made a new friend (yellow headed collared lizard). The trail was a little bit harder than we expected, but felt a sense of accomplishment when we returned to the parking lot.
