Triple Tree Aerodrome and the world's most perfect grass runway in Woodruff, South Carolina
Triple Tree Aerodrome in Woodruff, SC offers a 7,000-foot manicured grass runway and an iconic September fly-in pilots call unforgettable.
Triple Tree Aerodrome in Woodruff, South Carolina is home to one of the finest grass runways on Earth: a 7,000-foot-long, 400-foot-wide turf strip groomed to the standard of a championship golf green. Built by aviation enthusiast Pat Hartness and now run by a nonprofit foundation, it hosts the renowned Triple Tree Fly-In every September, where hundreds of aircraft land on grass so smooth pilots describe touchdown as landing on silk.
What Is Triple Tree Aerodrome?
Triple Tree is a private grass airfield in the upstate of South Carolina, tucked into rolling green countryside southeast of Greenville and Spartanburg, near the town of Woodruff. A glassy lake sits right off the end of the runway, and from pattern altitude the strip looks almost painted into the trees.
What sets it apart is the runway itself. At 7,000 feet long and 400 feet wide, it’s longer than many paved runways at regional airline airports — but it’s all grass. Most grass strips run 2,000 to 2,500 feet, leaving pilots doing nervous short-field math. At Triple Tree, you have room to spare.
The surface is the real signature. The turf is maintained with specialized mowers, rolling equipment, and constant attention to leveling and drainage so it stays firm and never goes soft. It’s widely regarded as one of the best-maintained grass runways anywhere in the world, and pilots routinely taxi back in stunned at how smooth the landing felt.
Who Built Triple Tree, and Why?
Triple Tree was the lifelong dream of Pat Hartness, a South Carolina businessman and dedicated pilot. He set out to build not just a good grass field, but the finest grass airfield in the world — and he actually did it.
Hartness bought the land and shaped the runway out of the region’s red Carolina clay. He laid down championship-grade turf and obsessed over every detail: mowing patterns, drainage, and rolling the surface flat the way a groundskeeper tends a putting green.
Crucially, he didn’t build it for profit. He built it to give it away. Hartness wanted a gathering place where pilots, families, and kids could celebrate flying, so he established a nonprofit foundation to ensure the aerodrome would outlive him. Hartness passed away a few years ago, but the foundation keeps the field — and his vision — flying.
What Happens at the Triple Tree Fly-In?
Every September, Triple Tree hosts its signature Triple Tree Fly-In, drawing hundreds of aircraft over several days. The lineup spans taildraggers, Cubs, Champs, Stearmans, Bonanzas, homebuilts, and warbirds.
There’s no large paved ramp. Pilots land on the grass, taxi over, and park their aircraft right beside their tents — camping under the wing is the whole point. Thousands of people spread tents and airplanes across acres of manicured green, with campfires at night and the morning smell of coffee, avgas, and cut grass.
The flying showcases sights you rarely see up close, thanks to the runway’s size and smoothness. Formation flights pass over the field, aerobatic aircraft work the sky, and one of the biggest draws comes from the giant-scale radio control community. These aren’t hobby-shop foam toys — they’re quarter- and third-scale fighters and turbine-powered RC jets with enormous wingspans, performing maneuvers that would tear the wings off a full-scale airplane.
What Is the Flying Experience Like?
During the fly-in, this quiet grass strip becomes one of the busiest pieces of airspace in the Carolinas. The foundation runs a special arrival procedure under a published NOTAM (Notice to Air Missions), with volunteer air boss teams sequencing arrivals and getting aircraft parked safely.
The standout experience is the touchdown. Because the surface is so meticulously maintained, there’s no rumble, no chatter through the landing gear, and no thump — just a smooth rollout. Pilots commonly describe it as landing on silk or butter, and many call it the best landing of their lives.
Outside of fly-in week, Triple Tree is a quiet private aerodrome operated by the foundation, and visits can be arranged in advance.
Why Triple Tree Matters to the Aviation Community
Triple Tree brings together worlds that don’t usually mix on the same patch of grass: the warbird crowd, homebuilders, antiquers, radio control enthusiasts, and families seeing airplanes up close for the first time.
Beyond the flying, the fly-in feels like part airshow, part county fair, and part family reunion — complete with vendors, forums, static displays, and plenty of South Carolina barbecue. The heart of it is the conversations: ask one question about someone’s restored 1940s taildragger and you may hear the full story of the rebuild.
At its core, Triple Tree is a monument to the joy and wonder of flight — a place built and given away so the experience could belong to everyone, year after year.
