Over Memorial Day weekend, my husband and I got away for a night and dispersed camp in the Unita National forest near the Mill Creek campground. We were planning to stay at the campground but it was closed, so we took advantage of free dispersed camping right outside. This is LNT(leave no trace) camping so be sure to pack out what you pack in. There are no amenities but you are along a water source so if you have a filter, you have water. All along the road there are open fields that can accommodate trailers and bigger parties then just a single tent. Near the campground (and the site we chose) is an outdoor education center which would be fun to go back and visit later in the summer. We really enjoyed camping here as it was peaceful and private (at least when we visited). Later in the summer that may not be the case, especially close to the road. The biggest issue may be the road. My Mazda3 was able to make it up, but the road was quite rutted and rough and you had to go through a small runoff stream. If you have a lowered vehicle, you may have a tough time but anything with a higher clearance will do just fine. Overall, I loved exploring a new area that I will definitely return to.
