FM 170: Rio Grande or Bust
We got a tip about taking "River Road" also known as Farm to Market Road 170, which runs in a loop from Marfa, TX along the Rio Grande through to Terlingua and Big Bend National Park.
We had been putting off the trip because temperatures along the Rio Grande were hitting 105F+. But, about two weeks into our stay in Texas, monsoon season started in earnest, which brings flash floods but also dropped temperatures by 20 degrees — we took advantage and it was an incredible drive.
Terlingua
Terlingua Ghost Town
In it's hey day this was a silver mining town. It's not truly a Ghost Town as folks still live here. But it's a tough and pretty desolate place. The vibe was "Slab City" with small houses. We didn't stay long.
Rio Grande & Big Bend Ranch State Park
The majority of the road by the Rio Grande runs through Big Bend Ranch State Park (the largest state park in Texas), and has plenty of places with river-access & camping. We only saw one group on the river...and no one camping. It's not surprising given August is usually the hotttest month in Texas.
Presidio
Although it has about twice the population of Marfa (where we are staying), this border town didn't seem to have too much going on...from what we could tell from our brief drive through town.
Shafter to Marfa
The remainder of the drive was a lot of brush country and ranches, with some Ghost Towns mixed in. Shafter was a former ranching and mining town; it was a speck of a place. There were still a few folks living there from what we could see.
