On our travels around southwestern Arizona, we stopped through at the River Island State Park, near Parker, Arizona.
River Island State Park is a smaller campground with 37 campsites, a ramada, a doggy park, ( that was very clean and Jakey loved), sandy beach, cove and boat launch. It also has a nice trail for hiking and quaint little cactus garden. Lots of places to stroll and hike- and we loved that! Lots of places to walk Jakey - bonus!
If you need to pick up some odds and ends, the River Island Market 1/4 mile down the road offers groceries, food, deli, gas, etc.. You are right beside the highway here, but traffic noise slows down at night and you really don't pay too much attention to it in the day.
This is one of the cleaner parks we stayed at and we enjoyed our stay!
