Devil's Den was my favorite place to go for a weekend while I attended UA - back in 1970-71.
It was the very first place I took my first trailer.
I can't recommend it highly enough.
There are 44 50/W/S sites for $32 per day in a big double loop. Very nice restrooms.
Devil's Den SP CampsitesDo not attempt to take AR-74 from Winslow / I-49/540 into the park. The grade and tight turns in the last mile not for the faint hearted, or trailers. The rig in your sig photo is too big for that route.
AR-170 coming in from the north from West Fork is the road to take.
Withrow Springs SP (30 - 50/W/S $32) on AR-23 - just north of the intersection with US-412 is also another great state park in the area - a bit east of Springdale.
Lake Fort Smith SP (20 - 50/W/S $32) is a new (to me) park built after the dam at Mountainburg was raised and turned Lake Fort Smith and Lake Sheppard Springs into one lake. The old Lake Fort Smith SP was moved. Do not attempt to follow a GPS to Lake Fort Smith SP - leave the interstate at Mountainburg and take US-71 north up the mountain to the sigh for the park.
