Just beyond the golf course is the municipal park’s campground. We stayed in the old section (no sewer) which had lovely thick trees offering welcome shade in 90+ degree weather. The sites sit on a small rise between the swimming pond and willow creek. For $20 we got power, water and WiFi. A real find in the middle of corn and soybean country. LeMars is also known as the Ice Cream Capitol as Blue Bunny is headquartered here.
Drive 240 S from Wall SD towards the NP for 6 miles. Look for a small dirt road on the left, it’s easy to miss. There are 3 radio towers near a Dispersed Camping area. You’ll notice the towers before the turn. Good cell service. Spectacular location. Most stay 1 night or 2. Best sites vacant by 10am and full by 4 pm.
