If you have spent time on the Swamp Rabbit Trail, there is a good chance you have ridden or walked past a massive piece of property without thinking much about it. Just a few miles north of downtown Greenville, in the Sans Souci area, sits a roughly 250-acre site that has been sitting largely undeveloped for years. That is about to change in a significant way.
Here is what the project is, what is being built right now, and what it could mean for this part of Greenville over the next several years.
What Used to Be Here
Before anything else, it helps to understand the history of this site because the history is exactly why it has sat undeveloped for so long.
The property is the former Union Bleachery site. The Union Bleachery dates back to the early 1900s and was a major part of Greenville's textile industry. After decades of industrial use, the property was left with significant environmental contamination and eventually became a federal Superfund site. That designation is the primary reason why this enormous piece of land, just a couple of miles from downtown Greenville, has remained largely unused for so long.
For years, there have been plans to clean it up and redevelop it. Now that process is finally moving forward in a real and visible way.

The Vision: On the Trail
The redevelopment project is called On the Trail. The original vision for this property is massive in scope. Plans have included residential development, restaurants and retail, office space, hospitality, green space, and additional trail connections. At its most ambitious, the master plan envisions as much as 20 million square feet of development across the entire site.
That number is worth keeping in perspective. This is not something being built all at once. On the Trail is a project that will be developed in phases over many years, and the plans will almost certainly evolve over time. The important thing to understand is the scale of what is being envisioned. This is not a single apartment complex going up beside the trail. The idea is to create an entirely new mixed-use district built around the Swamp Rabbit Trail. A significant portion of the overall property is expected to remain green space and floodway.
What Is Actually Being Built Right Now
People in Greenville have been hearing about the Union Bleachery redevelopment for years. What is different now is that the first major residential phase is actively moving forward.
The first phase is called Venture on the Trail. It is a 222-unit apartment community. The developer secured approximately $47 million in construction financing, with completion currently expected in 2027.
Venture on the Trail is planned to include studio, one-bedroom, two-bedroom, and three-bedroom apartments. Amenities will include a pool, fitness center, co-working space, pickleball courts, and a bike room. For a development built alongside the Swamp Rabbit Trail, the bike room and pickleball courts are fitting choices that match the lifestyle of the trail community.
The most important amenity, though, is not inside the building. It is right outside the front door. Direct access to the Swamp Rabbit Trail is the defining feature of this development and the element that ties the entire On the Trail vision together.
Why the Location Matters
To understand why On the Trail has so much potential, it helps to look at what the Swamp Rabbit Trail has already done to the destinations along its route.
Downtown Greenville and Falls Park anchor the southern end of the trail corridor. Unity Park adds another gathering destination. The Swamp Rabbit Cafe has become a well-known stop along the trail. Further north, Travelers Rest has built an entire small-town identity around trail access, with restaurants, breweries, and shops concentrated along its trail connection.
Each of these places is not just somewhere you ride through. They are destinations. People plan trips around them. Businesses have grown up around them. Real estate values in their surrounding neighborhoods reflect their presence.
On the Trail has the potential to create another major destination along the corridor. Instead of riding past a largely vacant former industrial site, the long-term vision would have riders passing apartments, restaurants, shops, public green space, and businesses woven directly into the trail experience. That is a fundamentally different version of this stretch of the Swamp Rabbit Trail.
The Infrastructure Investment Behind It
The residential development is not the only thing happening in this area. Greenville County has received more than $20 million in federal funding for infrastructure and trail connectivity in and around Sans Souci. That investment includes plans to improve connections through the Sans Souci area and link surrounding neighborhoods more directly into the Swamp Rabbit Trail network.
That matters because On the Trail is not happening in isolation. The trail connectivity improvements will make the Swamp Rabbit Trail more accessible to people who already live in this part of Greenville, while the development itself brings new residents, businesses, and activity to the corridor.
What This Could Mean for Real Estate
From a real estate perspective, this is one of the more significant long-term developments to watch in the Greenville market. When investment and new amenities come into an area at this scale, surrounding real estate typically becomes more desirable over time. That pattern has already played out along other parts of the Swamp Rabbit Trail. Properties near downtown Greenville, Unity Park, and Travelers Rest have all seen increased interest and value as the trail corridor developed around them.
That does not mean every property in the Sans Souci area is about to see a sudden jump in value. There are trade-offs that come with development and growth, and the full build-out of On the Trail is a multi-decade process. But more development, more amenities, and better trail connectivity in this part of Greenville will create higher land values and development pressure in the surrounding neighborhoods over time. For anyone who already lives in Sans Souci or the surrounding area, this is a project worth watching closely.
What to Keep in Mind
The original vision for On the Trail is valued at more than $2 billion. That is the ceiling of what has been planned, not the immediate reality. Phase one, Venture on the Trail, is moving forward with a defined timeline and secured financing. The larger vision, 20 million square feet of mixed-use development across 250 acres, is a long-range plan that will evolve significantly over the years it takes to complete.
The plans as they exist today are almost certainly not identical to what will ultimately be built. Large-scale redevelopment projects rarely are. But what is clear is that this property is finally moving from a decades-long holding pattern into active development. And it is happening directly along one of Greenville's most beloved and most defining assets.
The Swamp Rabbit Trail you ride five or ten years from now could look very different in this stretch of Greenville. And that is exactly what makes On the Trail one of the most important projects to follow in the Upstate right now.
