Rifle Gap State Park is built around the reservoir created behind the Rifle Gap Dam about six or seven miles outside of Rifle. It's main purpose seems to be to give the semi-local folks somewhere to take their motor boats. It's relatively small and since motor boats are allowed you will be able to hear them during the day. The noise was not obnoxious when we were there in early season but it probably gets more crowded in July and August and therefore louder. The boat ramp is set up to handle fairly sizeable boats and there were a number of fisherman out also in the early morning and evenings. It's a popular spot. If you want a little more quiet and some trees go up the road to Rifle Falls Campground but make reservations early for that one. It's small and fills up fast. Pinion Loop at Rifle Gap State Park is a small loop and allows only tents and small RVs. The loop is high on a hill overlooking the reservoir. There are two campsites (86 and 87) that directly face the view. I stayed in 87 and I recommend 86. This is also about the only loop in the park to offer any shade. I don't fish or water ski so a couple nights was all I needed to see it, get a few good pictures and make some nice memories of camping. The campfire in the evening overlooking the reservoir and the gap with many stars and a full moon was truly awesome. We camped here in a Travel Trailer.
