Monahans Sandhill State Park, Tx

Lots of sand - we stopped in on the way by to have lunch - I personally would camp at BALMORHEA STATE PARK 85 miles west - they have sites with water,electric and TV plus a huge spring fed pool
But my favorite is Davis Mtn State park 120 SW of Sandhills - has full hookups with cable - we were there again 2 weeks ago

Texas has at least 27 state parks with full hookups
