Triple Tree Aerodrome, the Seven-Thousand-Foot Grass Runway in South Carolina Mowed Like a Golf Green, and the Fly-In Where Ramp Culture Still Means Sleeping Under Your Wing

Triple Tree Aerodrome is a private grass airfield just south of Greenville, South Carolina, built around a 7,000-foot-long, 400-foot-wide turf runway that is mowed and striped like a golf course. Founded by the late Pat Hartness, it charges no landing or ramp fees and is best known for its fall fly-in, where pilots camp under their wings and gather around campfires. It is widely called the finest grass runway in the world.

What Makes Triple Tree’s Grass Runway So Remarkable

The runway is the headline, and it earns it. At 7,000 feet long and 400 feet wide, it is longer than the paved strips at many general aviation airports pilots use every weekend - except this one is turf, cut tight, clean, and striped.

The grass is maintained to golf-green standards. That level of care is unusual anywhere in aviation, and it is a big part of why the field draws pilots from across the country.

Standing on it at dawn, with dew burning off the grass and fog settling in the low ground between the runway and the lake, it is easy to understand the reputation. Many pilots consider it the finest grass runway in the world.

Who Built Triple Tree Aerodrome

The field did not come from an airport authority or a public grant. It came from one man: Pat Hartness, a local businessman and lifelong pilot who loved airplanes and people in roughly equal measure.

Hartness wanted to build a place rather than a business - somewhere pilots could land on grass the way flying used to feel, camp under their wings, and simply be around aircraft and the people who love them. He shaped the land, planted the grass, and opened the gates.

The defining choice was to keep it free. There is no landing fee and no ramp fee. The operating philosophy is that every arriving pilot is a welcome guest.

What the Triple Tree Fly-In Is Like

The signature event is the Triple Tree Fly-In, the field’s fall gathering. It is a fly-in, not an airshow - no jet noise, no announcers, just props turning down the line, run-ups in the distance, laughter from the tents, and breakfast cooking in camp.

The flightline is a cross-section of aviation. A bright yellow Piper Cub sits nose to the grass beside a Cessna 170, next to a polished 1930s Beechcraft Staggerwing biplane, next to a homebuilt Van’s RV riveted together over five years of weekends. The culture treats every one of them as equal.

Families camp right off their wing struts with tents, camp chairs, and coolers. One family flew in from Tennessee - a four-hour trip in a fifty-year-old airplane - and their youngest called it the best day of her life before they had even landed.

How to Fly Into Triple Tree’s Grass Strip

The approach comes in over trees, with a tree line off both ends and the threshold set in slightly, giving the classic grass-strip sight picture - except the “strip” is an enormous carpet of green.

That size is the trap. Because the runway is so wide, long, and perfect, it does not look like the narrow gray strip pilots are trained on. Your eyes tell you that you are higher than you actually are, which leads to flaring high and ballooning.

The advice from experienced pilots on the field is simple:

Fly the numbers and trust your airspeed rather than the sight picture.
Don’t let the wide green surface fool you into flaring high or ballooning.
Expect a soft settle, not a thump or chirp - done right, you simply hear the grass under the wheels as you roll out.

The Ramp Culture: Camping, Campfires, and Community

Triple Tree exists to preserve a fading tradition: at the end of the day, you stay. Pilots pitch a tent off the wing strut or throw a sleeping bag in the back of the airplane and spend the night on the flightline with a few hundred like-minded people.

After dark, campfires appear all down the line. Pilots wander from fire to fire with a folding chair, sit down with strangers, and stop being strangers within a couple of minutes - the shared act of flying in is enough. The stories follow: first solos, weather that closed in, the airplane someone wishes they had never sold.

The event runs almost entirely on volunteers - hundreds of them who spend a week of their own vacation marshaling airplanes, driving golf carts, cooking, and hauling trash for free. The marshallers take visible pride in parking aircraft wingtip to wingtip in lines as straight as a runway centerline.

The spirit is deliberately the opposite of where much of aviation has drifted - away from locked gates, badge readers, and ramp fees, and back toward open doors and free grass. One pilot who restored a wartime Fairchild military trainer over eleven years in a barn said he brings it here because people actually walk up, look closely, and understand what that work means. In his words, at Triple Tree you are not showing off - you are sharing.

Triple Tree’s Mission Beyond the Fly-In

Hartness’s vision reached past the annual gathering. The field hosts youth programs that bring kids around airplanes, runs events for wounded veterans, and maintains a dedicated area for radio-control model aircraft - Hartness wanted every corner of aviation, from foam models to Staggerwings, to have a home there.

Pat Hartness has since passed away, but the Triple Tree Aerodrome Foundation he established keeps the gates open, the grass green, and his idea alive. The result feels less like an organized event than a standing invitation left open for anyone with an airplane and a free weekend.

Key Takeaways

Triple Tree Aerodrome sits just south of Greenville, South Carolina, and is centered on a 7,000-foot by 400-foot grass runway maintained like a golf green.
It was built by lifelong pilot Pat Hartness and charges no landing or ramp fees - arriving pilots are treated as guests.
The annual fall Triple Tree Fly-In emphasizes quiet gathering, wing camping, and campfire community over airshow spectacle.
The wide, perfect turf can fool pilots into flaring high, so the local advice is to fly the numbers and trust your airspeed.
The nonprofit Triple Tree Aerodrome Foundation sustains the field and supports youth programs, wounded veterans, and radio-control flying.
