Ask anyone who walks Radnor Lake on a regular basis what happened at the park this year and you'll get the same two-part answer. It flooded, iced over, and lost trees in January. It reopened in February, weeks ahead of what anyone expected. What most people won't mention, because it isn't really news yet, is that the nine acres Radnor Lake has been quietly adding to its eastern edge still don't have a trail on them. Those are two different clocks running on two different stories, and if you use this park the way Oak Hill residents do, the difference matters more than either headline on its own.
What Actually Got Fixed First
The January ice storm that moved through the region left Radnor Lake in rough shape. The Nashville Banner reported that park officials said no part of the property was left unscathed. Roads were blocked, power was down at the Barbara J. Mapp Aviary Education Center, and the trail system needed real work before anyone could safely walk it again.
The recovery moved faster than the park itself projected. The report also said Radnor Lake reopened at 1 p.m. on a Monday in late February, about 60 days sooner than officials had originally estimated. That turnaround leaned heavily on volunteers rather than a large staff expansion. A Saturday cleanup day drew 45 people. The following Monday, another 33 showed up to help clear debris from the access trail and the East Parking Lot, and to rehabilitate the South Lake Trail. Six volunteer days were planned in total.
That's the fast story. The park you can walk right now, on the trails you already know, is largely back to normal because a few dozen neighbors gave up their weekends to make it that way.
The Nine Acres Nobody's Walked Yet
A longer-term project is the addition of roughly nine new acres on the park's eastern side, near the intersection of Franklin Road and Old Hickory Boulevard. This isn't a sudden acquisition. It's the latest increment in a partnership between Friends of Radnor Lake, the Harris family, and the State of Tennessee that has been running for more than two decades. Between 2011 and 2017 alone, that partnership added 89 acres to the park. The current parcel is the next piece of a corridor meant to eventually connect a new trailhead and one-acre parking lot in Brentwood to Otter Creek Road inside the existing park boundary, forming a route of more than 3.5 miles once it's finished.
None of that is open yet. As of the most recent reporting, park staff were still hoping to open the property sometime in 2026, and even that was conditional on other work finishing first. Cleaning up the parcel and demolishing existing houses on it was expected to run through this year. The trail itself, called Harris Ridge, hasn't been built at all. According to Friends of Radnor Lake, the terrain is the reason: the incline of the ridge means the trail will take a large number of volunteer labor hours to construct, and work on it is expected to continue into 2026 and 2027. No additional staffing has been added by the state for this specific project. It's being built the same way the storm damage got cleared, one volunteer shift at a time, except this job doesn't have a 60-day fast track. It has a ridge.
How the Two Timelines Compare
Put the two timelines next to each other and the difference is clear. Radnor Lake recovered from a disaster in under two months with volunteers helping with storm cleanup. Adding new trail mileage is a longer-term project. Expansion here runs on a decades-old partnership between a nonprofit, a landowning family, and the state, built out acre by acre and now, ridge foot by ridge foot.
That gap matters because of what's already happening on the trails that do exist. The park spans 1,389 acres but offers only 7.75 miles of trail, all of it day-use only, according to the Town of Oak Hill's own community page. Friends of Radnor Lake puts annual visitation at around 2 million people. That's a lot of foot traffic funneled into a small trail network with limited parking that fills quickly on any weekend with decent weather. The nine acres and the Harris Ridge corridor would meaningfully ease that pressure once built. Right now, they're still houses being cleared and a ridge waiting on volunteer hours.
If you've been telling yourself you'll wait until the new trail opens before getting back into a regular Radnor Lake habit, the honest read is that you might be waiting a while.
What's Actually on the Calendar This Fall
None of that changes what's usable right now, and the park's ranger-led program schedule is one of the more overlooked parts of living this close to it. Depending on the season, Radnor Lake runs:
- Canoe floats on the lake itself
- Astronomy night hikes, particularly useful once the September heat breaks
- Programs focused on snakes and other reptiles found in the park
- Birds of prey programs, tied to the park's role as a migration stopover
- Off-trail land acquisition hikes, which sometimes walk the very parcels tied to the Harris Ridge project
That last one is worth flagging if you've been curious about the expansion. It's a rare chance to see the acreage in question before there's a marked trail on it at all.
The Practical Version, for People Who Use This Park Weekly
A few details are easy to forget once you've walked Radnor Lake a hundred times and stop reading the signage. The Otter Creek Road trail is the only one where dogs, jogging, and bicycles are permitted. Every other trail is foot traffic only, for hiking, photography, and wildlife observation. The Lake Trail is built to accommodate all-terrain wheelchairs, which isn't true of the rest of the network given the elevation changes on routes like South Cove Trail and Ganier Ridge Trail. Parking is limited to marked spaces, and on any pleasant morning those spaces go fast enough that arriving early is less a suggestion than a requirement if you want a spot near a trailhead.
None of that is new information if you've lived in Oak Hill for years. What is new is the reminder that this park, for all its permanence, is currently mid-repair in one place and mid-construction in another, and those two projects are not moving at the same speed. The storm damage is behind you. The ridge is still ahead.
If you're the kind of Oak Hill resident who already treats Radnor Lake as an extension of your own yard, keep an eye on the Friends of Radnor Lake volunteer calendar. The Harris Ridge Trail is one of the rare local projects where showing up with a pair of gloves actually moves the completion date closer, acre by acre, the same way the last 89 did.
If living within walking distance of a park like this is part of what you're weighing for your next move in Oak Hill or anywhere else in Middle Tennessee, Brock Daniel is always glad to talk through what that actually looks like day to day. Let's Connect.
