Atkinson Park Campground at the north west corner of Cascade offers free camping at the north end of the park. Camping at the park appears to most suited to RV camping as they don't want any camping outside of the parking pads due to not wanting damage to their sprinkler system. That being said it appears that you should have room for your vehicle and a tent as long as you did not have a trailer with you. The park has a pavilion with running water, and BBQ grills. Flushing toilets are also available. The individual camp sites do not have tables or fire rings. Camping is limited to three nights. It appears that the campground has 4 sites, sites 2, 3 and 6 are marked, another spot which I assume is site 1 looks the same as 2& 3, could not find any place that might be sites 4 and 5. Additional recreational activities are available during your stay. The park has a nice sized playground, tennis courts, horseshoe pits and a skate park. For the RV crowd there is a free RV dump at the entrance to the campground. The campground sits along side the interstate so you will have plenty of road noise throughout the night. While this would not be my choice for a location to camp, it is a free camp ground that would be a good spot to stay the night for a tired traveler
