Greenbrier is the Tennessee-side corner of Great Smoky Mountains National Park, about 20 minutes east of Gatlinburg. A partly paved road follows a river to a picnic area and the trailheads for Porters Creek and Ramsey Cascades. Parking longer than 15 minutes needs a tag, and the park does not recommend swimming in its rivers.
I would pick Greenbrier over the main strip any day the plan is a river and a trail. We have done Smokies days with nieces and nephews along. A cove like this is where I would take them, because there is room to spread out and nothing to buy. Packing for a river day is where I over-pack most, so the list below is the short version.
Greenbrier entrance Smoky Mountains
You turn off US-321 east of Gatlinburg, and the road in is quiet compared with the stop-and-go through town. The entrance road is partly paved and follows the river upstream to the picnic area, with trails fanning off into the surrounding mountains. Greenbrier is a heavily forested cove known for wildflowers, waterfalls, fishable streams, and historic structures and cemeteries. Directions come from the Ramsey Cascades page: drive six miles east of Gatlinburg on US-321, turn at the Greenbrier entrance, then follow the signs 4.7 miles to the trailhead.
The Porters Creek trailhead sits at the dead end of Greenbrier Road. Our Cosby guide covers the next quiet corner of the park along the same side. The two pair well if you have a full day and a full tank.
Greenbrier parking
Any vehicle parked longer than 15 minutes needs a parking tag. The park’s fee page lists $5 for a day, $15 for a week and $40 for a year. The tag is not an entrance fee. It must carry your license plate number and sit in the vehicle as a physical copy. An America the Beautiful pass does not replace it, and a tag is good for one vehicle only.
Our parking tag guide walks through where to buy one. Lots at the trailheads are small, and parking is limited in peak season. A weekday or an early start beats circling.
Greenbrier picnic area
The picnic area has 12 sites, each with a table and a charcoal grill. There are vault toilets, and the area runs year-round. A pavilion that seats 70 can be reserved up to a year ahead on recreation.gov. That is worth knowing if you are planning a family reunion.
The river runs right beside the tables. Bring the cooler and the card game, and leave the evening for somewhere else. The park closes some picnic areas each summer evening for cleaning, so plan to be packed up before dark.
If you are traveling with younger cousins, our Smoky Mountains with kids guide has more ideas. The picnic area suits them well. Shallow edges, flat ground and a short walk from the car make it an easy first stop.
Greenbrier trails
Two hikes are worth the drive. Porters Creek offers flowers, old buildings and a waterfall. Ramsey Cascades offers the park’s tallest waterfall. The table lays out the distances so you can match one to the hours you have.
| Hike | Round trip | Difficulty | Notes |
|---|---|---|---|
| Porters Creek to Messer Barn and the hiking club cabin | 2 miles | Moderate | Historic buildings; allow 1 to 3 hours on this trail |
| Porters Creek to Fern Branch Falls | 4 miles | Moderate | 40-foot waterfall; steeper just before the falls |
| Porters Creek to backcountry campsite 31 | 6 miles | Moderate | Mostly uphill past the falls |
| Ramsey Cascades | 8 miles | Strenuous | More than 2,000 feet of climbing; 105-foot falls |
The Old Settlers Trail is the other name you will see around Greenbrier. It suits people who care more about old homesites than waterfalls. Ask at a ranger station for its current length before you commit a day to it.
A half day here goes like this:
- Arrive early, with the tag already on the dash.
- Hike Porters Creek to Fern Branch Falls, and allow up to three hours.
- Eat lunch at the picnic area beside the river.
- Leave before dark, and before the lot turns into a puzzle.
Ramsey Cascades trail
Ramsey Cascades is the tallest waterfall in the park. The National Park Service puts the round trip at 8 miles, with more than 2,000 feet of climbing. It calls the hike strenuous. The trail is steep, rooty and rocky, so plan on most of a day. Your knees will notice the 2,000 feet on the way down.
The walk up goes through old-growth cove hardwood forest. You pass tuliptrees, basswoods, silverbells and yellow birches. The trees are half the reward, and the falls themselves drop 105 feet.
The park reopened the trail seven days a week in November 2024, after a three-year restoration. Its closures list is the place to confirm the trail and road are open, so check it the morning you go.
Wear sturdy shoes with ankle support. Leave the dog and the bike at home, because neither is allowed on this trail. Stay off the rocks around the falls, which are slick with mist and algae.
Porters Creek Trail
Porters Creek is the one I would hand to anyone with a short window. The park’s trail page rates it moderate. It lists 2, 4 and 6 miles round trip to the barn, the falls and the campsite. Allow 1 to 3 hours, depending on how far you go.
Roots, rocks, high footlog bridges and stream crossings make it harder than the mileage suggests. The trail steepens just before Fern Branch Falls. Past the falls it stays mostly uphill.
Spring is the reason to go. Bloom at lower elevations usually peaks in mid- to late April. The Greenbrier cove is one of the park’s wildflower corners. The park also hosts a week-long Spring Wildflower Pilgrimage each spring, and the trail is busy in that window.
Pets are not allowed on this trail, and a parking tag is required. Expect limited parking and crowds in peak season.
Greenbrier swimming hole Smoky Mountains
On a hot afternoon you will see families sitting in the shallows. The rule behind that is not an invitation. The park’s water safety page says water recreation is not recommended. It adds that swimming and inner tubes have caused innumerable injuries, and that there are no lifeguarded swimming areas in the park.
Rocks and logs can sit just under the surface, so do not dive or jump in. Skip any rain-swollen stream rather than wading across it. Stay off the rocks near waterfalls too.
Levels can rise fast after thunderstorms upstream. That can happen even if no rain has fallen where you are standing. Cold water can also cause hypothermia within minutes.
Greenbrier tubing
Leave the tube in the car. The park does not recommend tubing in its rivers. The Greenbrier channel is rocky, and a rapid that looks gentle from the bank moves faster than you expect.
Here is the short list for a river afternoon. Our Smoky Mountains packing list has the rest.
Bring:
- Your parking tag, displayed, with the plate number on it
- Sturdy shoes with ankle support if you plan to hike to Ramsey Cascades
- A towel and dry socks for the picnic area
- A trash bag, so every scrap leaves with you
Leave:
- The inner tube
- The dog, since neither big trail allows pets
- Flip-flops and sandals, which the park rules out for Ramsey Cascades
- The third pair of shoes, which you will not wear
Bear safety Smoky Mountains
Greenbrier is bear country. It is illegal to willfully approach within 50 yards (150 feet) of a bear. The same goes for any distance that disturbs or displaces it.
Lock the car, because bears can open car doors. Leave nothing edible on the seats while you hike. Put all garbage and food scraps in a bear-proof can, or carry them out. Never feed wildlife, since violations can bring fines up to $5,000 and up to six months in jail.
Greenbrier FAQ
Is Greenbrier worth visiting?
Yes, and I would go for the forest and the river even if you never hike to a waterfall. I would spend a morning on Porters Creek. I would save Ramsey Cascades for a day with nothing else on the schedule. If you want arcades and pancake houses, stay in town. If you want a sandwich beside loud water, come here.
How far is Greenbrier from Gatlinburg?
It is about 20 minutes by car. The entrance sits six miles east of Gatlinburg on US-321. The Ramsey Cascades trailhead is another 4.7 miles up the entrance road.
Are dogs allowed at Greenbrier?
Dogs are allowed in the picnic area and along the roadway on a leash no longer than 6 feet, but not on the trails. Porters Creek and Ramsey Cascades both bar pets. I travel with dogs. For a Greenbrier hike I would line up a sitter.
Can you swim in the Smoky Mountains?
Not safely, and the park does not recommend it. Swimming and tubing are discouraged in park waters. There are no lifeguarded swimming areas, and rain upstream can raise a river fast. Wading at the edge on a dry day is about as far as most people go.
