Clayton Lake State Park. Never been to it, however.
Sugarite Canyon State Park by Raton is a neat area.
Near Amarillo: Never been to the state park, but have read about it & would like to make it over there someday.
Palo Duro Canyon State Park as well as Caprock Canyons State Park, from what I have read, seem like very neat areas to see.
Caprock Canyons State Park & Trailway would make a neat place to check out. One I would like to see. For perhaps a neat experience,
Copper Breaks State Park near Quanah sounds pretty cool.
