Dinosaur Valley State Park
You’re standing in the Paluxy River, cool water flowing over your ankles, looking down at a three-toed footprint the size of a dinner platter pressed into the limestone. This print was made 113 million years ago—give or take a few million—by a theropod dinosaur that walked through soft mud along the shore of a vast shallow sea. That footprint dried, was buried under layers of sediment, turned to stone, and waited 113 million years for you to find it.
Welcome to Dinosaur Valley State Park, one of the most remarkable paleontological sites in the world and the only place on Earth where you can walk through a riverbed among hundreds of perfectly preserved dinosaur tracks. Located an hour southwest of Fort Worth in the small town of Glen Rose, this Texas treasure offers not just a glimpse into the age of dinosaurs, but also swimming holes, 20+ miles of trails, and camping among the limestone bluffs of the Hill Country.
The park preserves trackways of both theropods (meat-eating dinosaurs walking on two powerful legs) and sauropods (massive long-necked herbivores leaving elephant-sized footprints). When paleontologist R.T. Bird discovered the sauropod tracks here in 1938, it was the first proof that these giant dinosaurs walked on land rather than floating in swamps—a discovery that rewrote everything we thought we knew about sauropod behavior.

The Dinosaur Tracks: A 113-Million-Year Story
The tracks at Dinosaur Valley formed during the Early Cretaceous period, when this part of Texas was a shallow coastal zone along the edge of an ancient inland sea. Dinosaurs—both carnivores and herbivores—walked through soft, limy mud that perfectly preserved their footprints before hardening into limestone.
How the Tracks Were Made
- 🦖 Step 1: Dinosaurs walk through soft, wet mud along a tidal flat
- ☀️ Step 2: The mud dries and hardens in the sun
- 🌊 Step 3: Incoming tides deposit layers of sediment over the tracks
- ⛰️ Step 4: Over millions of years, layers compress into limestone
- 💧 Step 5: The Paluxy River erodes overlying rock, exposing the tracks
Types of Tracks
| Track Type | Description | Dinosaur |
|---|---|---|
| 🦖 Theropod | Three-toed, bird-like prints; up to 24″ long | Acrocanthosaurus (large carnivore) |
| 🦕 Sauropod | Massive, elephant-like; up to 3 feet across | Sauroposeidon or similar (giant herbivore) |
The Five Track Sites
The park contains five primary areas where dinosaur tracks are visible, all along the Paluxy River:
| Site | Track Types | Highlights |
|---|---|---|
| ⭐ Main Track Site | Sauropod + Theropod | R.T. Bird’s original discovery; best preserved sauropod trackway |
| 💧 Blue Hole | Theropod | Tracks on limestone ledge + deepest swimming hole (20ft) |
| 💃 Ballroom Site | Theropod | Hundreds of tracks in all directions—”dancing” dinosaurs |
| 🔍 Denio Branch Site | Various | Less visited; potentially lower water levels |
| 🦶 Other Sites | Various | Scattered tracks throughout riverbed |
⚠️ Track Visibility Warning
Water levels dramatically affect track visibility. After heavy rains, tracks may be underwater or covered in sediment. During droughts, tracks are exceptionally clear. Call the park (254-897-4588) before visiting to check current visibility conditions.
The R.T. Bird Discovery
In 1938, paleontologist Roland T. Bird was investigating reports of giant footprints near Glen Rose. What he found changed paleontology forever: a complete sauropod trackway showing a massive herbivore walking on solid ground. Until then, scientists believed sauropods were too heavy to walk on land and must have lived mostly in water. Bird’s discovery proved they were fully terrestrial—one of the most important paleontological finds of the 20th century.
Swimming: Blue Hole & Beyond
The Paluxy River provides excellent swimming, with the star attraction being the Blue Hole:
| Swim Spot | Depth | Features |
|---|---|---|
| 💙 Blue Hole | ~20 feet | Crystal clear; rope swing; dinosaur tracks on ledge |
| 🏊 Main Track Area | Shallow | Wading depth; excellent for kids; tracks visible |
| 💧 Various Pools | Varies | Scattered along Paluxy River |
🏊 Swimming Tips
- Water clarity is best during dry periods with low flow
- After rains, the river may be murky and higher
- No lifeguards—swim at your own risk
- Summer weekends are crowded; arrive early
- Bring water shoes—the riverbed is rocky
Hiking & Biking Trails
The park offers over 20 miles of trails for hiking and mountain biking through diverse Texas Hill Country terrain:
| Trail | Distance | Difficulty | Highlights |
|---|---|---|---|
| 🦖 Dinosaur Track Trail | 0.5 mi | Easy | Main access to track sites along river |
| 🌲 Limestone Bluff Trail | ~2 mi | Moderate | River overlooks, bluff views |
| 🚴 North/South Loop | ~10 mi | Moderate-Difficult | Mountain biking; technical sections |
| 🐴 South Primitive Area | Varies | Moderate | 100 acres; equestrian access |
The World’s Fair Dinosaurs
Near the park entrance stand two massive fiberglass dinosaur replicas—a T-Rex and a Brontosaurus—that have a remarkable history of their own. These sculptures were created for Sinclair Oil’s exhibit at the 1964 New York World’s Fair, where they wowed millions of visitors.
After the fair, they were donated to Texas and have stood sentinel at Dinosaur Valley since 1970. Though scientifically outdated (we now know Brontosaurus posture was different), they remain beloved icons and a perfect photo op for families.
Camping
Dinosaur Valley offers multiple camping options:
| Camp Type | Sites | Features |
|---|---|---|
| 🔌 Water/Electric | ~40 | RV-friendly, pads, fire rings |
| ⛺ Walk-In Tent | ~8 | More private, short walk from parking |
| 🥾 Hike-In Primitive | ~6 | Backcountry experience, 1-2 mile hike |
