This trail, a rutted and bumpy dirt road about 7 miles long (I think), takes you into the desert at a necessarily slow speed. Roll your windows down, look at the geology and the plants, read the brochure ($1.00 at the entrance to the trail) and learn about them, smell the flowers (literally this time of year), and unwind. For those of us too old, infirm, or lazy to hike the Big Bend's trails this is a way to experience the place in comfort. Highly recommended.

Dagger Flats is known for the giant dagger yucca forest at the end of the 5 mile dirt road, which is easily passable except after a rain. Even with the severe drought, enough of these wonders have survived to make the trip worth it. While these giants are found elsewhere in the park, these are the only ones easily accessible by car.Be sure to pick up the road guide at the beginning of the road. Plants along the road are identified and will make the drive much more interesting and seemingly much shorter. Along the way are some really large crystal veins along the road. In the sun shine they will glisten with colors and make for some interesting photographs. At the end of the Trail there is an old tank with numerous tin cans and other historical items to explore.About half way back the old Ore Road takes off to the right (south). If you are in a car, don't even think of trying the 26 mile long high clearance road.
