From Alpine we drove to Marathon, Texas so we could enter Big Bend at the Persimmon Gap visitor center. That is the main road into the center of the park. There were two campgrounds we could fit into and they were at the far edges of the park. We chose Rio Grande Village for this visit. Neither campground had hook-ups and neither had shower facilities. 
We passed through this tunnel to get to our campground.
Our first day at Big Bend was extremely windy and cool so we decided to drive through the park to familiarize ourselves with trails and different programs available to us. We stopped at Boquillas Overlook to view the Rio Grande.
From Cottonwood Campground we traveled west to Santa Elena Canyon.
From there we took the Old Maverick Road back to the Maverick Junction entrance.
Our next stop was the Chisos Basin where the lodge is located. We arrived there at 4:00--30 minutes after the visitor center closed.
We returned to our campground and planned the rest of our stay.
For our second day in the park we chose to hike Hot Springs Historic Trail. The trail starts at the remains of an old village. This building was the general store.
Along the trail we were surprised to turn a corner and see these gorgeous yellow flowers growing out of the cliff just below prickly pear cactus.

At one time the hot springs was a health resort and spa. All that is left is the foundation where the hot springs continue to flow into the Rio Grande. And yes, the water is very warm--105 degrees!
