South Mountain's Log Trail Is Disappearing Because It Was Never Actually Inside the Preserve

If you have spent any part of the last decade walking, running, or riding the Log Trail on South Mountain, you have been using a route that Wildlands Conservancy never put on its own map. Not because nobody built it. Because part of it sits on land the Conservancy does not own, and the person who does own that land is about to harvest the timber on it. When that happens, the Log Trail dead-ends in the woods.

That single fact changes how you should think about the trail system a lot of Emmaus residents treat as permanent. The preserve feels like a fixed, protected backdrop to daily life here. Most of it is. But the map has always had an asterisk, and this fall is when that asterisk becomes visible.

The Preserve's Boundary Isn't Where You Think It Is

South Mountain Preserve is Wildlands Conservancy's oldest holding, protected in 1973 and now covering 440 acres with close to 12 miles of trail. That's the official, permanently protected core, reachable from the main entrance at 554 Alpine Street, from Kline's Lane, or from the Ithaca Street play lot on the Boroline Park side. Inside that footprint, the trail network is genuinely secure: Alpine Street, Uplands, Mountain Top, Trout Run, Bloodroot, Bug, and the ADA-accessible Kline's Lane connector are all Conservancy land, cared for and mapped as such.

The Log Trail sits at the edge of that story rather than inside it. According to the local mountain bike club that has volunteered on these trails for years, part of the route is at least a century-old road, and the trail itself predates the Conservancy's official map by at least ten years. It was never added to that map because the people maintaining it knew part of the corridor left Conservancy property and crossed private land. That distinction did not matter much while the private landowner had no plans for the parcel. It matters now, because that owner is preparing to harvest timber, which means the existing Log Trail route will soon end in the middle of the woods rather than connecting through.

What Actually Changes on the Ground

The good news for anyone who uses this system regularly: this is a rerouting story, not a closure story. Club volunteers, coordinated by a longtime member working with Wildlands Conservancy, have been building a replacement trail at the top of the preserve, on the east side of the power line corridor, across from the existing Mountain Top Trail. Part of the new route will functionally take over what the Log Trail used to do, connecting hikers and riders through that upper section without depending on land the Conservancy doesn't control.

Here is how the current trail system breaks down, and where the Log Trail sits relative to the rest of it:

If your usual loop touches the Log Trail, expect the marked route to shift toward that new upper-mountain segment rather than simply vanish. If you have never used it and stick to Alpine Street or the Kline's Lane connector to Emmaus' own Homestead Park side, none of this changes your Sunday walk.

The larger point is the one worth carrying with you past this specific trail: a chunk of what feels like protected open space around Emmaus depends on informal, decades-old agreements with private landowners, not on deed restrictions. That's true of a lot of small-town trail systems. It is rarely stated out loud until something like a timber harvest forces the issue.

The Same Six Weeks, Triangle Park Fills In Too

While the mountain sorts itself out, the flatter part of Emmaus is running its own seasonal handoff. The Emmaus Farmers' Market has held its Sunday spot at Triangle Park since 2003, and it is still a producer-only market, meaning every vendor grew, raised, or baked what they're selling rather than reselling someone else's goods. Through November, hours stay at the regular 10 a.m. to 1 p.m. window before the market shifts to its winter schedule of 10 a.m. to noon on the second and fourth Sundays from December through April.

The vendor roster shifts with the seasons too. Salvaterra's Gardens, a family farm out of Alburtis that has been growing for twenty years, joined the market in 2025 after looking for new outlets closer to home. The current lineup also includes newer additions like Dragonfly Hill Farm & Kitchen, Hausman Farm Distillery, Hijinx Brewing, Hilltop Haven Wine, and The Worthy Dessert, alongside market regulars like North Star Orchard, which brings its heaviest apple selection of the year during exactly this stretch of the calendar.

Then the parade calendar lands on top of the market's peak weeks. The Emmaus Halloween Parade traces its roots back to borough council minutes from 1919 and 1921, which makes it one of the longer-running community traditions in the Lehigh Valley. The tied-in 5K race is set for Saturday, October 17, 2026, and the parade itself follows that same evening, the way it always has, race first, parade right after at 7 p.m. The route runs from Keystone and Ridge Streets west on Ridge to 6th, over to Walnut, south on 9th to Chestnut, then east to Main and back to Keystone. The Xfinity Food Truck Court sets up in the borough lot on Main between 3rd and 4th, and St. Margaret's Episcopal Church, at Keystone and Elm, opens its doors that night with food and public restrooms as it has for years. If you want to support the parade committee directly, donation boxes typically show up at Yergey's Brewery, the Emmaus Public Library, and South Mountain Cycle in the weeks leading in.

Trick-or-treat night is set separately by Borough Council closer to the date, so it's worth checking the borough's own calendar rather than assuming it lines up with parade night.

A Borough That Rewards Paying Attention

None of this is complicated, but all of it requires knowing where to look rather than assuming the map from three years ago still holds. The trail you've ridden without thinking twice about crosses a boundary you didn't know existed. The market you shop out of habit adds two or three vendor names a year that are worth actually stopping at. The parade that feels like it has always happened the same way still moves its exact date around the calendar based on a 5K race schedule set months in advance.

Emmaus is a small enough place that these things are knowable. They just aren't handed to you. That's true of the trail system, and it's just as true of the housing stock on the streets around Triangle Park and up toward South Mountain, where a hundred years of additions, porch rebuilds, and small lot subdivisions mean two homes on the same block can have very different stories.

If you're weighing a move within Emmaus, thinking about what a renovation might actually be worth here, or just want a straight answer about a property you're watching, Jeff Adams has spent enough time in this borough's actual houses, not just its listing sheets, to give you one.
