RV Parks In Knoxville, Iowa

41.3208° N, 93.1094° W

Quick Overview

Knoxville is a small central Iowa town with two big draws for RVers: it is the Sprint Car Capital of the World, home of Knoxville Raceway and the National Sprint Car Hall of Fame, and it sits a short drive from Lake Red Rock, the largest lake in Iowa. Between the racing and the reservoir, this is a place where you either come for a specific weekend or use it as a relaxed base to explore Marion County and the Dutch town of Pella just up the road.

Camping here leans heavily public, which keeps prices friendly. The closest option is the county-run Marion County Park Campground on the west side of Knoxville, with 99 sites, most of them full-hookup gravel pads with 50-amp electric, water and sewer for around $30 a night. That is a rare combination of full hookups at a public-park price, and it puts you minutes from both the raceway and downtown.

Out toward Lake Red Rock, the U.S. Army Corps of Engineers and Iowa DNR run the lakeside camping. Howell Station is the popular Corps campground below the dam, with over 140 electric sites that handle rigs up to 80 feet, open April through October. Elk Rock State Park sits right on the water with electric sites, a modern shower building and a dump station, plus equestrian trails. For a large private option in town, RV's Full Facility Campgrounds runs 350 sites just off Highway 14.

Big rigs do fine here. Howell Station is built for long rigs up to 80 feet, and the Marion County full-hookup gravel pads take larger motorhomes and fifth-wheels without trouble. The highways in and out, IA-14 and IA-92, are easy two-lanes, and Des Moines with its interstate access is only about 40 miles northwest. Just confirm site length at the state park and county loops, where a few sites run shorter.

Timing is everything in Knoxville. The town revolves around the Knoxville Nationals in August, the biggest sprint car race in the world, when every site for miles books out a year in advance and the place is electric. Summer in general is peak for racing and the lake. Spring is lovely and lines up with Tulip Time in Pella, fall turns crisp and quiet with fall color around the reservoir, and winter closes most campgrounds down. Plan around a race or the lake, book early, and you will get the most out of a stay here.

Traveling to Knoxville by RV

Getting to Knoxville is easy by Iowa standards. IA-14 runs north-south through town and IA-92 runs east-west, both good two-lane highways that any rig can handle. Most RVers come in off I-80 through Des Moines, then drop about 40 miles southeast on IA-5 and IA-14. Pella is only 15 miles north, and Oskaloosa about 20 miles southeast, so you are never far from services.

To reach Lake Red Rock and the Corps campgrounds, follow the marked routes northeast out of Knoxville toward the dam and Elk Rock State Park; the roads are paved and fine for big rigs, though the campground loops themselves can be wooded and tight in spots. Knoxville has fuel, groceries and the basics, and Pella and Des Moines cover any larger propane fill or RV-supply needs. Cell service is solid in town and reasonable around the lake. Watch for race-weekend traffic in August, when the whole town swells, and give yourself extra time to reach the raceway or your campground. Otherwise the driving here is relaxed and flat, classic Iowa two-lane touring.

Before You Go: RV Trip Essentials

Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Knoxville, Iowa, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.

Check your RV insurance coverage

A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.

Know your roadside assistance options

RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.

Decide about an extended warranty early

Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.

Set up a travel rewards card for fuel and fees

A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Knoxville

Camping around Knoxville is a good value, largely because the best options are public. The standout is Marion County Park Campground, where full-hookup gravel sites with 50-amp electric, water and sewer run around $30 a night, which is remarkably cheap for full hookups this close to town. The Corps of Engineers campgrounds at Lake Red Rock, including Howell Station, and Elk Rock State Park sit in a similar low range, generally in the low-to-mid $20s for electric sites, though most of those offer electric only rather than full sewer at the site.

The large private option, RV's Full Facility Campgrounds off Highway 14, runs a bit higher, into the $30s and up depending on the site and season. The big exception to all of this is race week: during the Knoxville Nationals in August, demand spikes and rates and minimum stays climb sharply everywhere within range of the track. Our honest read is that the county campground is the best all-around value for full hookups and location, the Corps and state sites win for lakeside camping on a budget, and you should simply expect to pay a premium if you are here for the big race.

Explore the Knoxville Area

A few things worth knowing before you roll into Knoxville. First and most important, if you want to camp here for the Knoxville Nationals in August, book a full year ahead. The race is the biggest sprint car event on the planet, the town fills completely, and campsites near the raceway are gold. Even the county campground and lake sites go fast for that week. Second, for any race weekend, the Marion County Park Campground on the west side of town puts you closest to the track with full hookups.

Third, do not skip Lake Red Rock. It is the biggest lake in Iowa, with beaches, boating, fishing and a long trail system, and the Corps campgrounds like Howell Station are among the nicest public camping in the state. Fourth, time a spring trip around Tulip Time in Pella, 15 minutes north, when the Dutch town blooms and the bakeries are worth the drive. Finally, remember most campgrounds here close for winter, so plan a spring-through-fall visit and confirm dates, since Iowa winters shut the lakeside sites down hard.

Frequently Asked Questions About Dump Stations in Knoxville

What are the best RV parks in Knoxville, IA?

The best all-around choice is Marion County Park Campground on the west side of town, with 99 sites, most full-hookup gravel pads with 50-amp electric, water and sewer for around $30 a night, and an easy drive to both the raceway and Lake Red Rock. For lakeside camping, Howell Station is the popular Corps of Engineers campground below the Red Rock dam, and Elk Rock State Park sits right on the water with electric sites. If you want a large private campground in town, RV's Full Facility Campgrounds runs 350 sites off Highway 14. Match your pick to whether you want full hookups near town or a spot on the lake.

Do RV parks near Knoxville have full hookups?

The county campground does, which is the headline. Marion County Park Campground offers full hookups on most of its 99 sites, with 50-amp electric, water and sewer on gravel pads, and that is unusual for a public park at its price. The lakeside options are different: Howell Station and the other Corps of Engineers campgrounds, along with Elk Rock State Park, generally offer electric hookups only, with water spigots and a dump station rather than sewer at each site. RV's Full Facility Campgrounds in town offers electric on all sites. For true full hookups with sewer, the Marion County campground is your best bet.

How much does RV camping cost in Knoxville?

Camping here is a good value most of the year. Marion County Park Campground charges around $30 a night for full-hookup sites with 50-amp service, which is a bargain for full hookups. The Corps of Engineers sites at Lake Red Rock, including Howell Station, and Elk Rock State Park run in the low-to-mid $20s for electric sites. The large private option, RV's Full Facility Campgrounds, runs into the $30s and up. The exception is the Knoxville Nationals in August, when rates and minimum stays climb sharply everywhere near the track, so budget more and book early if you are coming for the big race.

How far ahead should I reserve a campsite near Knoxville?

For the Knoxville Nationals in August, reserve a full year ahead, no exaggeration. The race is the biggest sprint car event in the world, the town fills completely, and campsites near the track are booked out well in advance. For ordinary summer weekends and Lake Red Rock lakeside sites, several weeks to a couple of months of lead time is smart, since the Corps campgrounds like Howell Station are popular. The Marion County campground and Elk Rock State Park also fill on nice summer weekends. Midweek stays and the spring and fall shoulder seasons are far easier, and you can often book close to your arrival date outside of race week.

When is the best time to go RV camping near Knoxville?

Summer is the peak season, with warm weather, racing at Knoxville Raceway and full access to Lake Red Rock, though it is also the busiest and most humid. If you want the racing energy, August and the Knoxville Nationals are unbeatable, but book far ahead. For quieter, cooler camping, fall is excellent, with crisp air, fall color around the reservoir and thinning crowds. Spring is mild and green and lines up with Tulip Time in nearby Pella in May. Winter closes most campgrounds down, so plan a spring-through-fall visit. Our favorite balance of weather and open sites is late spring and early fall.

Can big rigs camp near Knoxville?

Yes. Howell Station, the Corps of Engineers campground below the Red Rock dam, is built for long rigs and accommodates RVs up to 80 feet, so even the biggest fifth-wheel or diesel pusher fits. The Marion County Park Campground full-hookup gravel pads also take larger motorhomes and trailers comfortably. The highways in, IA-14 and IA-92, are easy two-lanes, and I-80 through Des Moines is only about 40 miles away for interstate access. The spots to double-check are a few of the wooded, older loops at Elk Rock State Park and some county sites, which can run shorter, so confirm site length when you book a long rig.

Are there public or state park camping options near Knoxville?

Yes, and public camping is actually the strength here. Elk Rock State Park sits right on Lake Red Rock with electric sites, a modern shower building, a dump station and equestrian trails. The U.S. Army Corps of Engineers runs several campgrounds around the reservoir, with Howell Station the most popular, offering over 140 electric sites for rigs up to 80 feet from April through October. The county also runs the excellent Marion County Park Campground in town with full hookups. Reserve the state park through Iowa State Parks, the Corps sites on Recreation.gov, and the county sites through Marion County, especially for summer and race weekends.

What is there to do around Knoxville besides camping?

Knoxville is the Sprint Car Capital of the World, so start with Knoxville Raceway and the National Sprint Car Hall of Fame and Museum, which is worth a visit even when there is no race running. The huge draw is the Knoxville Nationals each August. Just northeast, Lake Red Rock, the largest lake in Iowa, offers boating, fishing, beaches and a long trail system for biking and hiking. Fifteen miles north, Pella is a charming Dutch heritage town famous for Tulip Time in May, windmills and bakeries. Add Des Moines about 40 miles northwest for city amenities and you have plenty to fill several days between the track and the lake.

What is the Knoxville Nationals and how does it affect camping?

The Knoxville Nationals is the biggest and most prestigious sprint car race in the world, held at Knoxville Raceway each August and drawing tens of thousands of fans to this small town. For RVers it is the single most important thing to know about camping here, because it completely transforms availability and pricing. Campsites near the track, including the county campground and the Lake Red Rock sites, book out roughly a year in advance, rates climb, and minimum-stay requirements kick in. If you want to experience it, plan far ahead and expect a premium. If you would rather avoid the crowds, simply steer clear of that August week and you will find the area calm and affordable.

Is Lake Red Rock worth visiting from Knoxville?

Absolutely. Lake Red Rock is the largest lake in Iowa, a U.S. Army Corps of Engineers reservoir just northeast of Knoxville, and it is the natural companion to a camping trip here. You get boating, excellent fishing, sandy swimming beaches, a wildlife-rich shoreline and a long paved trail system that is great for biking and walking. The Corps campgrounds like Howell Station and Elk Rock State Park put you right on the water. Birders love the reservoir, especially during migration, and the dam and visitor area make an easy outing. Even if you came for the racing, budget a day for the lake; it is one of the best outdoor spots in central Iowa.

What is the weather like for camping in Knoxville?

Central Iowa gives you four distinct seasons. Summers are warm and humid, with highs in the 80s and the occasional strong thunderstorm, which is peak camping and racing season. Spring is mild and green, warming through the 60s, and lines up with Tulip Time in Pella. Fall is crisp and colorful with cool nights, one of the most pleasant times to camp around the lake. Winter is genuinely cold, with highs near freezing, regular snow and most campgrounds closed for the season. Watch for severe weather in spring and summer, keep an eye on the sky, and plan your visit for the warm-weather months when the campgrounds are open.

Where can I get fuel, propane and groceries near Knoxville?

Knoxville has fuel stations, a grocery store and the everyday basics, which covers most stays comfortably. For a big propane fill, major RV supplies or a larger grocery run, Pella is only 15 miles north and Des Moines about 40 miles northwest, both with plenty of options. The Corps campgrounds, Elk Rock State Park and the county campground all have dump stations, and the Marion County full-hookup sites let you skip a separate dump trip. Since services are lighter out at the lake, top off fuel and stock up in town before you head to a lakeside campground, especially if you are staying a while at Howell Station or one of the quieter Corps areas.

Are pets allowed at campgrounds near Knoxville?

Generally yes, with standard leash rules. The Marion County Park Campground, the Corps of Engineers campgrounds at Lake Red Rock like Howell Station, and Elk Rock State Park all allow leashed pets in the campgrounds, and the private RV's Full Facility Campgrounds is pet-friendly too. The lake shoreline and trails make for good dog walking, though you should keep pets leashed near the beaches and watch for boat traffic. Iowa summers get hot and humid, so carry water for your dog and avoid the midday heat on the trails. As always, confirm each campground pet policy when you book, particularly if you travel with more than one animal or a larger breed.
