Champion Trees Near Lewis Center, Ohio: Where to Find Delaware County’s Living Giants
There’s a particular feeling that hits you standing next to a genuinely enormous tree. Not a big tree — a champion tree, one that’s spent two centuries quietly outgrowing every other member of its species in the state. Delaware County, just north of Columbus and minutes from Lewis Center, happens to be home to one of Ohio’s most impressive examples.
If you’ve searched for champion trees near Lewis Center, you’ve probably run into a mix of local blog posts, some accurate and some exaggerated. So let’s settle exactly what’s documented, where it actually is, and how you can go see it for yourself.
This guide covers Ohio’s Champion Tree Program, the record-holding Eastern Cottonwood at Alum Creek State Park, the measurement system behind these titles, other notable big trees in the area, and how you can nominate a giant tree of your own.
What Is a Champion Tree, Exactly?
A champion tree is the largest documented specimen of its species within a defined area, usually a state. In Ohio, that title is awarded through the Ohio Champion Tree Program, run by the ODNR Division of Forestry.
Importantly, ODNR is clear that champion status doesn’t confer any special legal status, ownership, or protection. It’s a voluntary conservation and record-keeping effort, not a regulatory designation. Nationally, American Forests has documented the largest known specimen of every native and naturalized tree species in the US since 1940, and Ohio currently claims 14 National Champion Trees on that registry.
How Champion Trees Are Scored
Every champion tree candidate is measured using the same three-part formula:
Total Points = Trunk Circumference (inches) + Height (feet) + ¼ × Average Crown Spread (feet)
- Circumference is measured at 4.5 feet above ground level (known as circumference at breast height, or CBH)
- Height is measured from the base to the highest living branch, typically using a clinometer or laser rangefinder
- Crown spread is averaged from the widest and narrowest points of the canopy
The tree with the highest combined score for its species becomes the official state champion, which is why a shorter, thicker tree can sometimes outrank a taller, slimmer one of the same species.
The Champion Eastern Cottonwood at Alum Creek State Park
The most significant documented champion tree in Delaware County, and the one most associated with searches for “champion trees near Lewis Center,” is the Eastern Cottonwood growing in Alum Creek State Park, near the intersection of Africa Road and Cheshire Road.
According to ODNR’s official Champion Trees registry, the tree currently measures:
- Circumference: 380 inches
- Height: 122 feet
- Crown spread: 102.9 feet
- Total score: 527 points
That circumference figure has genuinely shifted over the years in various field notes and photography records, ranging from around 358 inches in a 2008 account to 370 inches around 2011, before reaching its current 380-inch measurement. That kind of gradual change is completely normal for big-tree records; cottonwoods are fast-growing, and a healthy specimen can add a couple of inches in circumference annually.
Worth knowing before you visit: this tree has, at various points, been recognized as a national co-champion contender for the Eastern Cottonwood species, though the current National Champion Eastern Cottonwood grows considerably larger, in Nebraska. The Alum Creek tree remains, however, Ohio’s undisputed state champion for its species, and one of the largest trees of any kind in the state.
Getting There from Lewis Center
Alum Creek State Park sits in Delaware County, roughly a short drive from Lewis Center, with the park’s marina and visitor access connected via Lewis Center Road. To reach the tree itself:
- Park near the Alum Creek State Park marina
- Follow the Cheshire Loop trail
- Look for the multi-trunked giant just off the trail near Africa Road and Cheshire Road
A quick honest note for accuracy: while local content often frames this as a “Lewis Center champion tree,” the official ODNR record places it within Alum Creek State Park in Delaware County, with Lewis Center serving as the nearest well-known community and practical access point, rather than the tree’s literal listed location.
Other Notable Big Trees Near Lewis Center and Delaware County
While the Alum Creek cottonwood is the headline giant, it’s far from the only impressive tree in the region.
- White oaks: Several mature white oaks in and around Delaware County have trunk circumferences exceeding 200 inches, with some specimens estimated at over 200 years old, meaning they predate Ohio’s 1803 statehood
- American sycamore: Ohio’s champion sycamore, located in Ashland County near Jeromesville, scores among the highest of any tree species in the state; sycamores along the Olentangy River corridor near Delaware County regularly exceed 300 inches in trunk circumference
- Black walnut: A locally notable specimen near Lewis Center on private land measures roughly 211 inches in circumference
- Bur oak: Capable of living 300 to 400 years, with some regional specimens potentially predating European settlement of the area entirely
- Shagbark hickory and tulip tree: Both grow to impressive size in the region’s mature woodlands and river corridors
Highbanks Metro Park: Old Growth Along the Olentangy
Highbanks Metro Park, managed by Columbus and Franklin County Metro Parks along the Olentangy River, is one of the best places near Lewis Center to see genuinely old, large trees in a protected setting. The park’s oak-hickory forest, which makes up roughly 63% of Ohio’s woodland type overall, includes mature oaks with trunks in the 200 to 300 inch range and sycamores along the riverbanks that rival those found elsewhere in Delaware County.
While not every large tree at Highbanks holds official champion status, the park’s protected old-growth character makes it a genuinely rewarding stop for anyone interested in big trees, alongside Alum Creek State Park.
Why Delaware County Grows Such Large Trees
The size of these trees isn’t an accident. Several factors combine to create exceptional growing conditions in the region:
- Glacial soils: Retreating glaciers during the last ice age deposited deep, nutrient-rich till across Delaware County, giving root systems room to spread wide and deep
- Consistent water access: Proximity to Alum Creek, the Olentangy River, and their tributaries keeps moisture levels high, which particularly benefits water-loving species like cottonwood and sycamore
- Low historical disturbance: Protected parkland and certain undeveloped corridors have shielded some trees from clearing for centuries
How to Nominate a Champion Tree
One of the more genuinely fun parts of this program is that anyone can participate. If you spot a tree that looks unusually large for its species:
- Confirm the species accurately (apps like iNaturalist make this far easier than it used to be)
- Measure the trunk circumference at 4.5 feet above ground using a flexible tape measure
- Estimate height using a clinometer or laser rangefinder
- Measure crown spread at its widest and narrowest points, then average the two
- Submit your measurements, photos, and GPS coordinates to the ODNR Division of Forestry through the official Champion Trees program
- If your nomination is on private land, get the landowner’s written permission first
A trained forester will verify the measurements before your tree is added to the registry. If it outscores the current champion for its species, it earns the title.
Threats Facing Ohio’s Champion Trees
These living landmarks face real, ongoing pressures. The emerald ash borer has already devastated Ohio’s ash tree population since the early 2000s, and continued monitoring by ODNR tracks new invasive threats to oak, beech, and sycamore populations. Storms and tornado damage have affected some of the Alum Creek cottonwood’s multiple trunks over the years, and urban development remains one of the biggest long-term risks to unprotected specimens on private land.
Champion trees also provide genuine, measurable value beyond their size record. Large, mature trees support wildlife habitat and biodiversity, contribute meaningfully to carbon storage, and provide real ecosystem services like stormwater management and shade that reduces urban heat.
Planning Your Visit
If you’re heading out to see these trees for yourself, a little preparation helps:
- Best timing: spring for fresh canopy growth, or fall for color and better visibility of trunk structure once leaves drop
- Footwear: wear proper trail shoes or hiking boots, since roots and uneven terrain around large trees make sandals impractical
- Respect boundaries: many impressive specimens grow on private land; always get permission before approaching trees off public trails
If you’re planning any longer outdoor visit through wooded parkland, it’s also worth brushing up on which plants to avoid touching along the trail. Our poisonous plants finder is a handy reference before you head out, especially with kids or pets in tow.
A Quick Home Safety Note Worth Mentioning
Since a trip to see Ohio’s champion trees often means a full day away from home, it’s a good moment to double-check something closer to home before you head out: your smoke alarm coverage.
Working smoke alarms cut the risk of dying in a home fire by roughly 60 percent, according to the National Fire Protection Association’s smoke alarm research. It’s a simple thing to check before a day trip, and it costs nothing but a few minutes. Our smoke detector calculator can help you confirm how many alarms your home actually needs and where they should go, based on your layout and room count.
Bringing It All Together
The champion Eastern Cottonwood at Alum Creek State Park, just a short trip from Lewis Center, is genuinely one of central Ohio’s most impressive natural landmarks: a 380-inch-circumference living giant that’s been quietly outgrowing its species for generations. Add in the old-growth oaks and sycamores at Highbanks Metro Park, and Delaware County offers a genuinely rewarding day trip for anyone who appreciates the scale and history these trees represent.
Whether you’re visiting to see the record-holder yourself, or you’re inspired to go measure a candidate in your own backyard, Ohio’s Champion Tree Program is a rare example of citizen science that anyone can take part in, no forestry degree required.
