If you have driven Highway 133 past Six Mile any time in the last several years, you have probably passed the old Gap Hill Landing and wondered whether anything real was ever going to happen there. The ramp worked. The gravel lot filled up most Saturdays. But the promise of an actual marina on that stretch, the kind with covered dry storage and a place to eat after you tie up, has been a rumor on this end of the lake since a Charlotte utility filed paperwork with the federal government back in January 2021.
That paperwork is finally becoming concrete and steel. And in the same season the north end gets its long-delayed anchor, downtown Seneca is building something that has nothing to do with boats at all. Put those two projects side by side and you get a version of Lake Keowee that looks different from the one longtime residents have lived with for the last decade or two, where everything that mattered sat on the water and nothing much happened once you drove into town.
The Marina That Took Five Years to Become Real
In January 2021, Duke Energy's Lake Services filed a proposal with the Federal Energy Regulatory Commission on behalf of Mountain Lakes Marina LLC to redevelop the former Gap Hill Landing into what would eventually be branded Sunset Marina, at a cost of up to $15 million.
Donald Payne of Mountain Lakes Marina told the Journal at the time that "if all goes well," construction could start that same summer.
It didn't move that fast. More than five years is a long stretch for a boat ramp community to keep believing in a project, and plenty of people who live near Six Mile had written it off. But the pieces are landing now. According to the marina's own site, the plan for the property at 900 Gap Hill Road includes a courtesy dock with public restrooms, a cabana-style restaurant and bar, a new boat store, and dry stack storage built to hold 240 watercraft. Above the marina, the developers also planned 50 Class A motorcoach lots with Blue Ridge views and access to the finished facility.
As of this season, Sunset Marina already operates as a public marina with a remodeled ship's store, fuel dock, and a rental fleet, describing itself as the first true public marina on the lake's north end. The restaurant and the full dry stack buildout are still described on the marina's own site as work in progress, which is worth knowing if you have been waiting for the whole thing to be finished before you plan a trip there.
That timeline matters more than it might seem. For as long as most current residents have owned property here, the north end has been the quieter, less-served side of the lake, while the Seneca side has had a full-service marina for more than four decades. The north end is only now catching up.
Sunset Marina (Six Mile, north end) | Lake Keowee Marina (Seneca side) | |
|---|---|---|
History | Former Gap Hill Landing, redevelopment proposed 2021 | Family owned, serving the lake for more than 40 years |
Dining | Restaurant and bar planned, not yet open | No on-site restaurant, but Keowee Luxury Cottages guests get access to the seasonal Keowee Shores Grill & Cantina |
What's new this season | Remodeled ship's store, boat rental fleet, courtesy dock underway | New A-frame Keowee Luxury Cottages and houseboat rentals |
What it signals | The north end is finally getting boating infrastructure comparable to the Seneca side | The Seneca side keeps expanding past boating into overnight stays |
Lake Keowee Marina in Seneca has spent the last few years adding to what it already had, rolling out Keowee Luxury Cottages and houseboat rentals on top of its existing boat sales, service, and rental business. The north end isn't trying to out-build Seneca. It's trying to stop being the side of the lake without a real anchor.
Downtown Seneca Doesn't Need a Boat Slip Anymore
While crews work on the north end, a different kind of investment is landing about three miles away on Main Street, and this one doesn't care whether you own a boat.
Harper's Plaza, a set of three buildings the city of Seneca redeveloped after buying a 27,000 square foot vacant property downtown, is now home to Seneca Social Co., an entertainment venue combining duckpin bowling, interactive gaming, a restaurant and speakeasy with craft cocktails and drinks on tap, and an arcade alley across all three buildings at 233 Main Street. City Administrator Scott Moulder announced the project at a public strategic planning session, and Upstate Business Journal reported a grand opening slated for 2026. The most recent coverage available did not include a firm opening date, and Seneca Social Co.'s own site was still framing the venue as coming soon as of that reporting, so if you haven't seen an announcement with an actual date, you haven't missed one.
A block or two over, The Yard has opened as an outdoor dining and gathering space with a park-like feel, the kind of place built for lunch and a drink rather than a full night out. Construction was also underway, as of the most recent local reporting, on the Seneca Center for the Arts, a theater planned to seat roughly 700 people for concerts and community productions, which would give downtown a reason to stay open past dinner that it has not really had before.
None of this requires a dock. That's the point. For years, if you lived at Keowee and didn't own a boat, or the weather turned, or it was February, downtown Seneca was mostly a place to run errands. That's changing on a timeline you can actually track this year.
What Was Already Working on the Water
None of this is replacing what already draws people to the lake in the warmer months. A few spots have simply come back for another season without needing to reinvent themselves:
- The Lighthouse is open for the 2026 season, with upstairs seating for panoramic lake and mountain views and a more casual dining room downstairs.
- Cabana Lake Keowee, the seating area at The Lighthouse known for its Orange Crush cocktail and live entertainment, has returned for 2026 with lakeside dining after a day on the water.
- Keowee Shores Grill & Cantina continues as a seasonal waterfront hangout, the kind of place that doesn't need a marketing push because regulars already know where it is.
Those spots aren't new news. They're the baseline this year's changes are being built on top of.
What This Actually Changes If You Already Live Here
Put the two projects together and the shift is less about any single opening and more about where a Saturday can now start and end without leaving the area. If your dock or slip is near Six Mile, you're closer than you've been to actual boating infrastructure, fuel, rentals, and eventually a place to eat, without driving south to Seneca first. If you're closer to town, Main Street is finally giving you a reason to walk over that has nothing to do with the hardware store or the bank.
Expect the usual friction that comes with real construction rather than a ribbon cutting. Gap Hill Road will likely see equipment traffic through the rest of the buildout, and downtown Seneca's Main Street corridor may have the normal disruptions that come with finishing three buildings and a theater at once. Neither project has a hard completion date attached to it in anything published so far, so the honest answer if someone asks you when it's all done is that nobody outside the development teams knows yet either.
What's changed is the range of a normal weekend. For a long stretch, living at Lake Keowee meant your plans followed the water, because that's where the infrastructure was. This year, for the first time in a while, both ends of that equation, the boating side and the downtown side, are getting real money at the same time. That's not a marketing story. It's a construction schedule, and it's worth knowing which parts of it are already open and which are still just plans.
If you're weighing what any of this means for a property near the lake, or you're simply curious how these projects might shape values on the north end versus downtown Seneca, the team at Nest Realty Greenville knows this market block by block and is happy to talk through it, no pressure attached.
