6 RV Campgrounds In Ortonville, MN

45.3047° N, 96.4448° W

Quick Overview

Ortonville sits right where Minnesota meets South Dakota, making it a natural stopping point for RVers crossing the prairie. With several RV campgrounds in the area and some offering no-cost dump access, you've got options whether you're passing through or planning a longer stay near Big Stone Lake.

This isn't a sprawling metro with dozens of choices. It's a small town that punches above its weight for RV facilities. Most campgrounds cluster around the lake shore, which makes sense when you consider that fishing and water access drive tourism here. The newest addition, Lakeshore RV Park & Fruit Farm, adds a unique twist with seasonal produce available right on site.

Highway 12 runs straight through town, connecting you to Interstate 29 about 30 miles west in South Dakota. Highway 75 provides north-south access. The roads are RV-friendly with wide shoulders and good sight lines across this flat terrain. You won't wrestle with mountain grades or tight historic downtown streets here.

The campground scene reflects the area's outdoor focus. Expect full hookups at most paid sites, basic amenities, and owners who know the best fishing spots without you having to ask. Some facilities operate seasonally, so call ahead if you're traveling outside peak summer months. The split between free and paid options gives budget-conscious travelers real choices.

Traveling to Ortonville by RV

Highway 12 is your main east-west route through Ortonville, running 150 miles from the South Dakota border to the Twin Cities. It's a two-lane road with passing zones and handles big rigs without drama. Highway 75 provides your north-south connection, linking to Interstate 94 about 90 miles north.

State Highway 7 approaches from the southeast if you're coming from the Montevideo area. All these routes feature flat terrain with long sight lines, typical of western Minnesota prairie country. You'll find truck stops with RV-accessible fuel lanes in town along Highway 12.

Overnight parking at Walmart or similar big-box stores isn't common here since there aren't any. The local Cenex station can accommodate RVs for fuel but isn't set up for overnight stays. Your best bet for quick overnights is one of the campgrounds with dump stations. Some allow late arrivals if you call ahead.

Watch for agricultural equipment during harvest season, typically September through October. Combines and grain trucks use these highways heavily, and they don't stop quickly.

Dump Station Costs in Ortonville

The several stations around Ortonville split evenly with some (a portion%) offering free dump access and a portion% charging fees. This 50-50 split is better than many small towns where free options have disappeared.

Paid campgrounds typically charge $25-40 per night for full hookups, which includes dump access as part of your stay. The free dump stations usually require no purchase or registration, though one is located at a city park where courtesy suggests you're visiting the area.

If you're just passing through and need a quick dump, the free options save you $30-40 compared to booking a campsite. For multi-night stays, the paid campgrounds offer better value with electricity, water, and often Wi-Fi included. Seasonal rates drop significantly if you're planning extended stays during summer months.

A small park with Minnesota on one side of the water and South Dakota on the other. We walked the hiking club trail and the woodland was so verdantly green.

Explore the Ortonville Area

Big Stone Lake is why most people stop here, so plan your campground choice around water access if fishing or boating matters to you. The lake straddles the Minnesota-South Dakota border and offers walleye, northern pike, and perch. A Minnesota or South Dakota fishing license works, but check which side of the lake you're on.

Groceries mean a trip to either Willie's Supervalu or the local Dollar General. Stock up before you settle in at a campground because options are limited. The Supervalu has better produce and meat selection if you're planning to grill.

Cell coverage is decent in town with Verizon and AT&T, but it gets spotty at campgrounds farther from the main highways. Download maps and any information you need before heading to your site.

The Big Stone National Wildlife Refuge sits just north of town and offers hiking trails that are easy enough for families. It's worth a morning visit if you're staying more than one night. Fuel prices here typically run 10-20 cents higher than Twin Cities rates, so top off before you arrive if you're coming from the east.
