Great Smoky Mountains by RV: America's Most Visited Park

Great Smoky Mountains National Park draws more visitors than any other national park in the country — over 12 million per year. That's more than Yellowstone and the Grand Canyon combined. And unlike most national parks, it's free to enter.

The crowds are real, but so is the beauty. Ancient mountains, old-growth forests, cascading waterfalls, and some of the best wildlife viewing in the eastern US. Here's how to experience it by RV.

The park straddles the Tennessee–North Carolina border. The two main gateway towns are:

• Gatlinburg, TN: The most popular entry point, with the Sugarlands Visitor Center just inside the park boundary. Gatlinburg itself is touristy but has good services.
• Cherokee, NC: The quieter, less commercial entry on the North Carolina side. Home to the Oconaluftee Visitor Center and the Blue Ridge Parkway.

Size restrictions: The park has several roads with size restrictions. Clingmans Dome Road is closed to vehicles over 45 feet. The road to Roaring Fork Motor Nature Trail is closed to RVs entirely. Check the NPS website for current restrictions.

Traffic: Gatlinburg and the roads leading to the park can be severely congested, especially on summer weekends. Plan to arrive early (before 9 AM) or late (after 5 PM) to avoid the worst of it.

The largest campground in the park, with 220 sites. Located along the Little River, it's a beautiful setting with easy access to several hiking trails. Reservable through Recreation.gov.

Located at the end of the famous Cades Cove Loop Road. Excellent wildlife viewing right from the campground. Reservable.

On the quieter North Carolina side, near the Oconaluftee Visitor Center. Good base for exploring the southern part of the park. Reservable.

The quietest and least crowded of the major campgrounds. Located in the northeastern corner of the park, away from the main tourist corridors. First-come, first-served.

An 11-mile one-way loop through a historic valley with preserved 19th-century homesteads, churches, and grist mills. Wildlife is abundant — deer, black bears, wild turkeys, and coyotes are commonly spotted. The loop is open to vehicles Wednesday through Saturday; Tuesday and Wednesday mornings are bike/pedestrian only.

At 6,643 feet, Clingmans Dome is the highest point in the Smokies and the highest point on the Appalachian Trail. The observation tower at the top offers 360-degree views. The half-mile trail to the top is steep but short.

A 5.5-mile one-way loop through old-growth forest with historic cabins and several waterfalls. Closed to RVs — park at the trailhead and explore on foot.

One of the most popular hikes in the park, leading to dramatic rock formations and, eventually, to the summit of Mount LeConte. The first 2 miles to Alum Cave Bluffs are accessible to most hikers.

Every June, synchronous fireflies put on a spectacular light show in Elkmont. It's one of the most magical natural events in the eastern US. A free permit lottery (through Recreation.gov) controls access — apply in April.

The Smokies are home to approximately 1,500 black bears. You will likely see one. Keep food secured, never approach wildlife, and carry bear spray on hikes.

Other wildlife commonly spotted: white-tailed deer, wild turkeys, elk (reintroduced in 2001, now thriving in the Cataloochee Valley), and over 200 species of birds.

• Spring (April–May): Wildflowers, waterfalls running high, and manageable crowds.
• Fall (October): Peak foliage, cooler temperatures, and spectacular color. Also the busiest time of year.
• Winter (December–February): Snow-dusted mountains, empty campgrounds, and a completely different atmosphere. Some roads and facilities close.
• Summer: Hot, humid, and very crowded. If you go in summer, arrive early and plan activities for early morning.

The Smokies reward patience and early mornings. The crowds thin out before 9 AM and after 5 PM, and the light is better anyway.
