Heading south west from Flaming Gorge Dam, cross Cart Bridge and park off to the right. From the parking lot, head north and immediately drop down 30 feet on one of several trails, and then head west. (There is a prominent trail heading to the lake, don't go there). Walk west for 15-25 yards and look for cairns heading north. This trail will take you to the Flintstones area via a rock trail through junipers. If you miss this,the next trail with cairns heads north through dirt and cactus and will bring you to the Nip and Tuck boulder. All boulders are within a few minutes walk of each others so just get in there and find one to get oriented.
