What I have on the
Big Bend Area. We really enjoyed Balmorhea State Park & checking out
Fort Davis Nat'l Historic Site.
Not stopped here, but if your in the area,
Monahans Sandhills State Park. Near Pecos & Midland/Odessa on I-20.
Likewise off I-10, I have never stopped here, but have been tempted to do so, Caverns of Sonora, they say is a National Natural Landmark, a unique cave located 8 miles west of the town of Sonora, Texas, and a world-class cave. It does have camping as well.
http://www.cavernsofsonora.com/Caprock Canyons State Park & Trailway would make a neat place to check out. One I would like to see.
Ditto,
Copper Breaks State Park near Quanah sounds pretty cool.
Seems many of the small towns in West Texas have city RV parks, such as:
Littlefield city park near Lubbock. Likewise, near Clovis, NM,
Muleshoe city park.
Other Such ParksWe spend an overnight at a Walmart Supercenter - 702 West Loop 289, Lubbock 806-793-9686. There are more as well:
Walmarts.
