Ask a longtime Alexandria West End resident about the woods off Roanoke Avenue and you will get one of two answers. Either a shrug, because they have never heard of it, or a hushed, slightly proprietary description of a pond, a waterfall, and a wooden lodge tucked behind the Mark Center office towers. What almost nobody mentions is that this patch of forest changed hands a few years ago and quietly became public land. Walk it today, though, and it still behaves like the private estate it used to be. That gap between what Winkler Botanical Preserve is on paper and what it feels like on the ground is the whole story.
A Private Woods for Forty-Some Years
The land at 5400 Roanoke Avenue was not always scenic. According to Gardenvisit's survey of the site, it started life as a pig farm before Catherine Winkler Herman set aside 44 acres of it in 1979, in memory of her late husband Mark Winkler, a local real estate developer. Her daughter, Tori Thomas, a landscape architect, helped shape the early trails and ponds into something meant to represent the Potomac watershed in miniature. The result sat inside the Beltway, wedged between Seminary Road, the Mark Center, and I-395, functioning for decades as a private preserve that happened to let visitors in.
That distinction mattered. Because the Winkler Foundation owned and ran the property, it operated under whatever rules the family wanted, and the rules were strict. No bikes. No picnicking. No fishing or wading. The place stayed a well-kept secret largely because there was no reason for the foundation to advertise it.
What Changed in 2022, and What Didn't
That ownership structure shifted in September 2022, when the Winkler Foundation transferred the preserve to NOVA Parks, the regional park authority that also runs Cameron Run and Bull Run. The gift came with an additional $100,000 donation to ALIVE!, the Alexandria nonprofit that fights poverty and hunger, earmarked for families living near the preserve. On paper, a private easement became a public park.
NOVA Parks Executive Director Paul Gilbert put the situation plainly in a WUSA9 report on the transfer:
"Almost nobody knows it's here, and it's been here for years."
Gilbert said the goal was simple: more people finding a wooded escape close to where they already live and work. What he did not say, and what the ground rules make clear, is that becoming public did not mean becoming casual. NOVA Parks kept nearly every restriction the Winkler Foundation had in place. If you are picturing Winkler as the next Cameron Run, with picnic shelters and open lawns, recalibrate. This is a park that is legally open to everyone and functionally still run like someone's private woods.
The Rules That Still Read Like a Private Estate
The official NOVA Parks rules page is short, but it covers ground that trips up first-time visitors expecting a typical municipal park:
- Dogs must stay leashed at all times, and owners are responsible for cleanup.
- Bikes, scooters, skates, skateboards, and outdoor toys are not permitted anywhere on the trails.
- There are no picnic areas and no food or drink allowed beyond bottled water.
- Fishing, swimming, and disturbing the garden beds are all off limits.
- There are no public restrooms and no water fountains on site.
- Parking is very limited. NOVA Parks tells visitors to use unmarked, unreserved spots in the surrounding apartment complex as needed.
- Hours run roughly 8:30 a.m. to 4:00 p.m. daily, closed on major holidays, which is earlier than most people expect from a public park.
None of this is punitive. It is closer to the housekeeping rules a private landowner would have written forty years ago, carried forward almost verbatim by a public agency that inherited the land rather than designed it. If you show up at 5 p.m. expecting a longer window, or you bring a blanket for a picnic lunch, you will be turning around at the gate.
What You'll Actually Walk Through
The trail itself is short. AllTrails lists the Winkler Botanical Preserve loop at 1.1 miles with about 82 feet of elevation gain, an easy walk that most people finish in under an hour. What fills that mile is more varied than the distance suggests. The path moves through a mowed meadow, past a lily pad covered pond, alongside the Winkler Run streambed, over a few wooden footbridges, and past remnants of what was once a Magnolia Bog before reaching Catherine's Lodge, the small education building named for the preserve's founder.
One thing worth checking before you go: recent AllTrails reviews note that a section of trail near the pond has been closed for restoration work. It is a minor detour rather than a real obstacle, but it is the kind of on-the-ground detail that generic listings about the preserve tend to miss, because they were written before the closure and never updated. If you are planning a specific route, especially one that loops fully around the pond, build in a few extra minutes to find the workaround.
The lodge itself is not open for events or rentals. There is nothing dramatic waiting inside, just a quiet building with a porch and a couple of chairs, evidence that the preserve was built as a teaching tool for Alexandria City Public Schools rather than a destination with amenities. That is consistent with the whole property. Winkler rewards people who want forty-five quiet minutes away from traffic noise, not people looking for a full afternoon of park infrastructure.
After the Walk
Because parking is tight and there is nowhere to eat inside the preserve, most visitors end up a short drive away at the Shops at Mark Center on North Beauregard Street. Clyde's at Mark Center anchors the corner with an outdoor patio and, fittingly, its own koi pond out front, along with daily happy hour and free parking. A few doors down, Taqueria Picoso covers casual Mexican food if you want something faster after a walk. It is a small, unglamorous stretch of shopping center, but it is the natural second stop for anyone who just spent forty-five minutes among the trees and wants coffee or lunch without getting back on I-395.
The Takeaway for Anyone Nearby
What makes Winkler worth knowing about is not that it is scenic, though it is. It is that the preserve's public status is newer and thinner than most visitors assume. NOVA Parks owns the land now, but the experience of walking it was designed by a family, not a park planner, and that design has barely changed. Treat it like the quiet, rule-bound private garden it spent four decades being, not like the open civic park its new ownership might suggest, and the visit will match your expectations. Show up expecting picnic tables and long hours, and you will be disappointed by 4:05 p.m.
If you live in the West End and have never made the trip, it is worth doing once you know what you are actually walking into. And if you are the kind of person who notices when a place changes hands quietly and wonders what else has shifted nearby without much fanfare, that curiosity tends to serve you well in this part of Alexandria. Paul Gonzalez spends most of his time paying attention to exactly that kind of change across Alexandria's condo and neighborhood markets.
