Head east on 1st street and you will see a sign for the River Recreation Area "Picnic Fish Camp" it says, so, although not supported or advertised by MWR this is a base approved camping area with no fees or checkin required. Within a mile of the main base area you will begin to see gravel pullouts along the road. I pulled into a very large one at a closed quarry site, it could easily accommodate 30 or 40 of the biggest rigs! Its quiet, convenient, yet out of the way, and I'm the only one here. If you are just passing through and want a nice spot to dry camp this place would be hard to beat.
Rose and I stayed here 2 times this past summer and had a great time. It is boondocking at its best. Both times there was no one else there. We stayed there from Sunday night and left on Thursday afternoon each time. The fishing was great both times. On base is a rather large spring that is stocked with rainbow trout. We caught two each. Also the Big Piney river runs right by the campground. Our campsite was under a large oak tree and the people before us mowed the site with a lawn mower. The parking pad was gravel and level with a table on a concrete pad and fire ring. Our 35 ft motor home with toad fit it easily. We picked up some litter from all campsites. You can get water at the Sportsman Center. We plan on going back next summer!
