The insider read
Only public diamond mine in the world where you keep what you find. Rangers plow the search field after every rain — the 24-hour post-rain window is the gold (diamond) standard. Camp loop is a short walk to the field gate.

NPSInsider tip · America's first National River. The middle district (Tyler Bend) is the float-trip launch point for the 26-mile Pruitt-to-Tyler section — pair the camp reservation with the Buffalo Outdoor Center shuttle 4 weeks ahead.
Near Hot Springs
NPSInsider tip · Only full-hookup NPS campground in Arkansas — and only one of a few nationally. 3 miles from the Bathhouse Row historic district; you can soak in the same thermal water Native Americans used 500 years ago. Loop 200 has the largest rigs accommodated.
Near Morrilton
StateInsider tip · Arkansas's first state park. Mather Lodge sits above the camp — restaurant has the best Cedar Falls overlook view in the state. Book Area D loops for the largest pull-throughs; Area A is closest to the swimming pool but loudest.
Near West Fork
StateInsider tip · Hidden valley CCC park from the 1930s. The narrow access road has a 28-ft RV limit — no exceptions; rangers will turn longer rigs around. Yellow Rock Trail leaves from camp and is the photographer's golden-hour go-to.
