TTo start off this is an Idaho state park and requires a fee to enter (was $10)  This is a great place to go if theres swarms of climbers at the City of Rocks because of the fee which tends to drive away most dirtbag (endearing term for us) climbers haha.  There are a multitude of fantastic routes there and some good bouldering to be had as well.  Another one of the great things about this park is they have yurt, small house, RV, and tent sites, so no matter how you like to camp theyll be sure to get you into something comfy!
