Where to Stay Near Marietta

Marietta and Cobb County offer four distinct camping zones, each with its own character and distance-to-attraction trade-offs.

Lake Allatoona / Red Top Mountain Area

Located 20 miles north of Marietta on I-75, this zone is the most scenic and least commercialized. Red Top Mountain State Park and USACE campgrounds (Sweetwater and McKinney) offer lakefront sites with views and quieter nights. Most sites feature full hookups and pull-throughs. This area is best for RVers who prioritize natural setting and don't mind a 30-minute drive back to Marietta for dining and attractions. Parking fills quickly on summer weekends, especially around July Fourth and Labor Day.

Kennesaw / Acworth Corridor

Fifteen miles north on I-75, the Kennesaw and Acworth corridor hosts several private RV parks with modern amenities—full hookups, pull-throughs, Wi-Fi, and pull-out picnic tables. This zone sits closest to the Kennesaw Mountain trailhead, making it ideal for hikers who want no more than a 15-minute drive to the visitor center. Sites tend to be in suburban settings with paved roads and good cell service. Rates run $42–$60 per night, moderately higher than state park options but still below Atlanta hotel pricing.

Marietta City Parks and RV Areas

In-city RV camping in Marietta itself is limited; most city parks are day-use only. The practical focus for Marietta-proper visitors should be the Kennesaw/Acworth-area private parks listed above, which are close enough (15 miles) for convenient access while offering full-service camping infrastructure.

Smyrna / Cumberland

Southeast of Marietta, closer to the I-285/I-75 interchange, Smyrna and Cumberland offer more urban camping options and direct access to Truist Park. This zone is best for Braves fans or travelers using Hartsfield-Jackson Atlanta International Airport. RV parking is available in dedicated lots on game days (call ahead for reservations). Expect a 15-minute drive to the stadium from these campgrounds.

Things to Do Near Marietta

Kennesaw Mountain National Battlefield Park

America's first national battlefield park (established 1917) preserves the earthworks and cannon positions from the June 1864 Atlanta Campaign. The park spans 2,923 acres with 18 miles of well-marked trails. The 2,965-foot summit is accessible both by a scenic paved road with shuttle bus service and by a 2-mile hiking trail from the visitor center. On weekends, parking fills by 9 a.m.; arrive by 8:30 a.m. or use the overflow lot and shuttle. The visitor center displays Civil War artifacts, weaponry, and soldier correspondence. Best time to visit is April through October; wildflowers peak in May. Admission is free. Plan 3–5 hours for a full visit.

White Water Atlanta

This 49-acre water park on Marietta Parkway is the go-to summer destination for families. It features over 40 attractions: a 25,000-square-foot wave pool, 7-story water slides, the Hurricane River lazy river, and splash parks for young children. Open late May through September (weekends only in spring and fall; daily in summer). Ticket prices range from $40–$55 per person depending on advance purchase and date. Peak heat and crowds occur in July and August; arrive at opening (10 a.m.) to minimize wait times. It's approximately 11 miles from Red Top Mountain campgrounds, making a full-day excursion very feasible.

Truist Park / Atlanta Braves

The home of Major League Baseball's Atlanta Braves, Truist Park opened in 2017 and is located 15 miles southeast of Marietta in the Cumberland/Smyrna area. Game tickets range from $15 (upper deck, weekday) to $150+ (field level, weekend or popular opponent). RV parking is available in dedicated lots on game days; contact the parking office in advance to reserve a spot. The facility features on-site dining, a craft bar, and a plaza open on non-game days. The Braves' season runs March through October (and playoffs in October). Plan for 30–60 minutes of extra drive time on game days due to I-75 traffic congestion.

Marietta Square

The heart of Marietta's downtown, the historic square features 50+ restaurants, bars, galleries, and boutiques within easy walking distance. Glover Park, adjacent to the courthouse, hosts free concerts and community events throughout the year—jazz in summer, holiday lights in December. The nearby Marietta Museum of History and the Gone with the Wind Museum offer air-conditioned cultural stops. Parking is widely available and free or low-cost. Exit I-75 at Exit 267 and follow signs downtown. The square is a pleasant afternoon or evening outing for those camped in the Kennesaw/Acworth area (15–20 minute drive).

Chattahoochee River National Recreation Area — Cochran Shoals

Five miles south of Marietta in Sandy Springs, Cochran Shoals is part of the broader NRA and features a scenic 3.6-mile river loop trail. It's dog-friendly, extremely popular with Atlanta residents, and offers free NPS access. The trailhead has ample parking, restrooms, and picnic areas. Best time to hike is October through April when temperatures are mild and the river is lower. Summer can feel crowded on weekends.

Practical Tips for Marietta RV Camping

Timing and Parking at Kennesaw Mountain

Weekday visits are far less crowded than weekends. On Saturday and Sunday, the main parking lot fills by 9 a.m. from April through October. If you're a morning person, arrive by 8:30 a.m. or use the overflow parking lot with shuttle bus service to the visitor center (runs every 15–20 minutes). Parking is free.

I-75 Corridor Traffic and Sports Events

Truist Park game days cause significant I-75 gridlock in both directions. A normally 20-minute drive from Marietta to the stadium can stretch to 50–80 minutes on high-draw games (Friday nights, weekend games, playoff games). Plan your camp-to-park timing carefully. Leave 2+ hours before game time; stay at the venue longer after the game ends to let traffic clear, or return to camp later that evening.

White Water Atlanta Peak Season Strategy

July and August are peak months—hot, crowded, and with long lines for slides. Arrive at opening (10 a.m.) or visit on a weekday if your schedule allows. Bring reef shoes, sunscreen (reapply hourly), and a waterproof phone case. Season pass holders and advance online purchases move through gates faster.

Red Top Mountain State Park as Your Base

For a nature-first experience with easy access to Marietta attractions, Red Top Mountain State Park (20 miles north) is hard to beat. It's quieter than private parks, more scenic, and still within 30 minutes of Kennesaw Mountain, the square, and White Water Atlanta. Rates are lower ($28–$35 per night vs. $42–$60 for private parks), and the tradeoff is slightly fewer amenities (some sites lack full hookups). Reservations are strongly recommended April through September.

Cell Service and Connectivity

Cell service is strong throughout Cobb County, thanks to suburban Atlanta coverage. All major carriers (Verizon, AT&T, T-Mobile) have good signal at Red Top Mountain, Allatoona campgrounds, and private parks in Kennesaw/Acworth. Wi-Fi is included at most private RV parks and available at park offices and visitor centers. Red Top Mountain offers limited Wi-Fi near the campground office.

Children under 3 feet tall can enjoy the splash parks and lazy river. Parents or guardians must supervise children at all times. Life jackets are allowed but not required.

Is RV parking available at Truist Park on Braves game days?

Yes. Truist Park offers dedicated RV parking in designated lots on game days. Spots are limited and require advance reservation. Contact the parking office at Truist Park (404-522-7630) at least one week in advance, especially for popular games. Parking fees are separate from game tickets.

Is Marietta Square accessible from RV campgrounds, and is parking available?

Yes, Marietta Square is accessible by car (15–20 minute drive from Kennesaw/Acworth campgrounds). Street and municipal parking is widely available and free or low-cost. The square itself is fully walkable once you park. No RV parking is available on the square, so day trips are the typical pattern.

What's the drive time from Red Top Mountain State Park to Marietta?

Approximately 30 minutes via I-75 South to Exit 267 (Cobb Parkway). It's a straightforward drive with good road conditions. Allow extra time on game days or during peak summer weekends due to increased I-75 traffic.

Is cell service reliable at Allatoona campgrounds?

Yes. Cell service is strong at USACE campgrounds around Lake Allatoona (Sweetwater, McKinney, Holiday Harbor). All major carriers (Verizon, AT&T, T-Mobile) have good coverage. Wi-Fi is available at some campground offices but is not guaranteed at individual sites. Private RV parks in the area include Wi-Fi as standard.

Are Cobb County RV parks pet-friendly?

Yes. Most RV parks in Cobb County allow pets. Red Top Mountain State Park, Sweetwater USACE, and private parks all permit dogs and cats. Kennesaw Mountain National Battlefield Park is dog-friendly on trails (leash required). Chattahoochee River National Recreation Area is also dog-friendly. Pet fees vary; contact parks directly.

What's the best RV campground for Atlanta Braves fans?

The Smyrna/Acworth area (12–15 miles from Truist Park) is ideal for Braves fans. Smyrna/Cumberland RV Park or Acworth RV Resort offer quick access to the stadium and are close enough for a short post-game drive back to camp. Allow 30–60 minutes of drive time on game days due to traffic.

What I-75 exit should large RVs use when heading north from Marietta?

Large RVs heading north from Marietta should use I-75 north and take exit 271 (Wade Green Road) or exit 279 (Acworth) to avoid downtown Atlanta and tight overpasses. I-75 north is generally RV-friendly with wide lanes and long merge distances. Avoid I-285 (Atlanta's outer loop) and downtown interchange; use I-75 north as your primary corridor.

Is winter camping available near Marietta?

Yes, but with reduced availability. Red Top Mountain State Park remains open year-round (though some sites close). Sweetwater USACE and private parks operate seasonally or year-round, depending on management. January and February are quietest. No heated sites are standard. Reservation ahead is advised, especially for winter weekends. Verify with individual parks on amenity availability (showers, laundry) during winter months.
