Ohio isn’t known for mountains, but every state has a high point — and Ohio’s is hiding in plain sight. Campbell Hill, rising 1,549.09 feet above sea level just northeast of Bellefontaine in Logan County, is the highest natural point in the Buckeye State. Tucked onto the campus of the Ohio Hi-Point Career Center at 2280 OH-540, this unassuming hill pairs small-town Ohio charm with one of the coolest Cold War stories in the Midwest. It’s one of the best hidden gems in Ohio we’ve featured.
Where Is Ohio’s Highest Point?
Campbell Hill sits in Logan County, Ohio, just northeast of downtown Bellefontaine. Getting there is half the fun: drive onto the Ohio Hi-Point Career Center campus, keep going straight up the hill, and find the summit markers tucked between school buildings. First-time visitors often feel like they’re in the wrong place — keep going, you’re not.
Quick facts:
- Elevation: 1,549 feet (472 meters) above sea level
- Location: Logan County, near Bellefontaine, Ohio
- The marker: An Ohio Historical Marker plus a small marble slab from the U.S. Coast and Geodetic Survey with an “X” marking the exact summit
- Cost: Free to visit, open year-round
- The name: Honors Charles D. Campbell of Bellefontaine, who owned the land from 1898 to 1937
In 1900, the U.S. Coast and Geodetic Survey placed that marble marker at the summit, officially recording Campbell Hill as Ohio’s high point. More than a century later, the little “X” on the stone is still the spot where high-pointers from all 50 states stop to snap a photo.
Why Campbell Hill Exists: Blame (or Thank) the Glaciers
Ohio’s highest point isn’t in the rugged southeast — it’s on the flatter western side of the state, and that’s a geologic accident. About 10,000 years ago, the retreating Wisconsin Glacier flattened most of western Ohio, but it left behind a chain of limestone hills known as the Bellefontaine outlier in Logan County. Campbell Hill is the high point of that outlier, and the same hills hold the headwaters of the Mad River, Big and Little Darby creeks, and the Great Miami River.
The result: Ohio’s total elevation range spans from 455 feet at the Ohio River to 1,549 feet at Campbell Hill — a difference of 1,094 feet.
The Cold War Secret on Top of Ohio
Here’s what makes Campbell Hill more than a photo op. From 1951 to 1969, the summit was an active military radar station — Bellefontaine Air Force Station (P-73), home of the 664th Aircraft Control and Warning Squadron.
The timeline:
- January 1, 1951: The 664th AC&W Squadron is activated at Lockbourne Air Force Base
- October 1, 1951: The squadron moves to Bellefontaine, taking over the hilltop
- September 1, 1959: The unit is redesignated the 664th Radar Squadron (SAGE) as it joins the Semi-Automatic Ground Environment — the computerized air-defense network guarding North America
- September 30, 1969: The squadron is inactivated as defense priorities shift, ending the military era
During its Cold War years, the station’s radar scopes scanned the skies for Soviet bombers, with tracking data relayed through the SAGE network to direction centers — including the one at Custer Air Force Station near Battle Creek, Michigan. Military and civilian operators worked the scopes around the clock.
One enduring piece of local lore: NORAD’s annual Christmas Eve Santa-tracking broadcasts began in 1955 using radar data from the continental air-defense network the 664th fed — meaning the “eyes” that helped track Santa for kids nationwide may well have included this very hill.
After the Air Force left, the site got a second life. In 1974, the former base became a vocational education campus — today’s Ohio Hi-Point Career Center, which trains students from across the region in fields like robotics, healthcare, and skilled trades. Many of the old Air Force buildings are still in use.
Visiting Campbell Hill: What to Expect in 2026
What you’ll find:
- ✅ Free access, open year-round — it’s a school campus, so be respectful during school hours
- ✅ The Ohio Historical Marker and the original survey slab with the “X”
- ✅ A rotating (non-functional) radar antenna on display, a nod to the NORAD years
- ✅ A National Air Defense Radar Museum is now being established on the Ohio Hi-Point campus — check ahead for tour days and hours
- ❌ No visitor center, food, or fuel at the summit — plan restroom and snack stops in Bellefontaine before you head up
- ❌ No panoramic overlook — this is a gentle hilltop, not a cliff; don’t expect sweeping vistas
Tips for your visit:
- The summit is between school buildings — if you feel lost, you’re probably in the right place
- Autumn is gorgeous here, with the surrounding countryside glowing in fall color
- Pair it with a day trip: Bellefontaine’s downtown sits on Ohio’s first concrete street and is full of small-town charm — see our guide to scenic drives in Ohio for more route ideas
- The summit sits on a working school campus, and visitors are welcome during the week. If the main gate is closed, look for the pedestrian gate — or call Ohio Hi-Point at (937) 599-3010
Fun Comparisons: Myths and Neighbors
- Mt. Rumpke (the landfill myth): Rumors that a Cincinnati-area trash mound out-tops Campbell Hill aren’t true. Mount Rumpke in Colerain Township tops out around 1,075 feet — the highest landform in Hamilton County, but well short of 1,549.
- Ohio County, West Virginia: Its high point is higher — but it’s not in the state of Ohio. Confusing name, different place.
- Ohio’s second-highest point: The runner-up is the high point of Richland County near Mansfield (around 1,510 feet) — also glacial terrain, but outside the Bellefontaine outlier.
FAQ: Campbell Hill, Ohio’s Highest Point

2. Is Campbell Hill really the highest point in Ohio? Yes. At 1,549.09 feet above sea level, it’s the highest natural point in the state, confirmed by the U.S. Coast and Geodetic Survey marker placed in 1900.
3. What was the Cold War base on Campbell Hill? The 664th Aircraft Control and Warning Squadron (later 664th Radar Squadron), part of the SAGE/NORAD air defense network, operated Bellefontaine Air Force Station here from 1951 to 1969.
