Pull up AllTrails before a ride at Clear Bay this fall and you'll get an answer that's already wrong. The app still shows Thunderbird Loop as a live trail. Riders who've been out there this year keep leaving the same correction in the reviews: that loop doesn't exist anymore, not in the shape the map remembers it. One reviewer put it bluntly enough that the phrase stuck: it's dead, gone, and the ground it used to cover is starting to grow over.
That gap between what your phone says and what's actually on the ground at Lake Thunderbird is the story right now, not the fact that trails got renovated. Everyone who follows Norman news already knows renovations happened. What most people haven't sorted out is which numbers to trust, which loops survived, and why the county deliberately built fewer miles than it tore out.
What Actually Changed This Year
The Clear Bay trail system reopened to the public on May 27, 2026, after a rebuild funded by $1 million in American Rescue Plan Act dollars. The Cleveland County Economic Development Coalition led the project, working with Visit Norman, the Oklahoma Department of Tourism, and the Bureau of Reclamation, which has federal jurisdiction over the land since Lake Thunderbird itself is a drinking-water reservoir. The physical construction was handled by Rock Solid Trail Contracting, a firm out of Arkansas that specializes in sustainable trail design.
That last detail matters more than it sounds. The old system at Clear Bay was volunteer-built starting in the early 2000s, and it stayed that way for roughly 25 years. A local rider named Josh Jewell had been maintaining sections of it solo, weed wacker in hand, for about two decades. That's a lot of goodwill and not enough labor for 24 miles of singletrack, and it showed. Trails eroded into cupped trenches. Sections built too close to the shoreline flooded whenever the lake rose. And because Lake Thunderbird supplies drinking water to Norman itself, that erosion wasn't just an inconvenience for hikers. Sediment from the collapsing trail beds was washing straight into the water supply, and the Bureau of Reclamation was the one tracing the problem back to its source.
That's the actual reason the county didn't just patch the old trails. It rebuilt them from the ground up, and it built fewer miles on purpose.
The Mileage Numbers Don't Agree, and That's Worth Knowing
Here's where a resident-facing guide earns its keep instead of just repeating a press release. Coverage of the May 27 opening, including reporting from Oklahoma's public radio stations, described the rebuilt Clear Bay network as roughly 13.78 miles of new multi-use trail. But Visit Norman's own blog post from July 27, 2026, describing the same system, puts the total closer to 20 miles across five interconnected loops.
Both figures are probably right, just answering different questions. The 13.78-mile number likely reflects the newly constructed singletrack itself, the physical trail bed Rock Solid built from scratch. The "almost 20 miles" figure from Visit Norman appears to count the full interconnected network, including sections that predate the rebuild and still carry the same color-coded names. If you're planning a ride based on a single number you found online, check which system that number is describing before you commit to a route length.
The Five Loops, As They Stand Now
The current layout keeps the same color system longtime users will recognize, even though the trail bed underneath has changed.
| Loop | Distance | Difficulty | Entry Point |
|---|---|---|---|
| Green | ~1.5 miles | Beginner | Clear Bay main trailhead off Highway 9 |
| Yellow | ~1 mile | Beginner | Connects directly from Green |
| Red | ~1.25 miles | Intermediate | Follow Green to the junction |
| Blue | ~4.75 miles | Intermediate | Reaches the lakeshore with several climbs |
| Gold | ~10 miles | Expert | Separate trailhead on Thunderbird Dam Road, about a mile northeast of the Clear Bay entrance |
Gold is the one to know about specifically, because its trailhead isn't at the main Clear Bay parking area. It's off Thunderbird Dam Road, and the route includes bypasses, a bridge, and a rock drop that make it a different experience from anything else in the system.
There's also a four-mile equestrian trail in the Clear Bay area, separate from the hiking and biking network, with twelve built-in obstacles. It's open daily from dawn to dusk, but riders need to bring their own current negative Coggins test since there are no on-site stables. That's a detail worth knowing if you keep horses in the area and haven't been out that way since before the renovation.
What the Regulars Miss, and What They Don't
Ask around and you'll get a split answer on whether the trade was worth it. Some riders miss the old system's sprawl, the ability to string together an unplanned 20-plus-mile day out of loosely connected trail. The new network is tighter and more deliberate, built for consistency rather than volume. Others point out that the old trails were becoming genuinely unrideable in wet conditions, with sections underwater after heavy spring rain because they'd been cut too close to the shoreline in the first place.
What almost everyone agrees on is that the construction quality itself is a step up. The new sections have better drainage, cleaner sightlines, and a flow that the old volunteer-built paths never had, since they were laid out over 25 years by different people with different goals rather than a single coordinated design.
Planning a Fall Visit
A few practical things carried over from the old system and a few didn't. Helmets are required for anyone mountain biking the network. Dogs are welcome but need to stay on a leash. A parking pass is required to use the Lake Thunderbird lot, even though the trails themselves are free. Ticks and chiggers are still part of the deal in Oklahoma's Cross Timbers terrain, so bring repellent regardless of which loop you're doing.
If you want to make a half-day of it, Discovery Cove Nature Center sits at the south end of the lake near the Clear Bay entrance. It runs Wednesday through Sunday, 10 a.m. to 4 p.m., with a full-time park naturalist on staff and hands-on exhibits of native animals, furs, and artifacts. The center hosts recurring programs through the year, including Eagle Watch tours in winter and First Day Hikes every January. Admission is free, and it's an easy stop before or after a ride.
Why This Is Worth Tracking at All
A trail system doesn't usually make the local news twice in one year unless something underneath it changed. This one did. The mileage got cut because the old version was quietly damaging the water supply for the city built around it, and the fix ended up being a smaller, better-engineered network rather than a bigger one. That's a different story than "trails got an upgrade," and it's the version that actually explains what you'll find out there this fall.
If you're the kind of person who tracks what's changing around Norman, from a lake trail system to the streets nearby it, that habit tends to carry over into paying attention to the rest of the area too. Cross C Realty keeps an eye on both.
