Best Time to Camp at Split Mountain Group Campground
Experience the full drama of high desert seasons at Split Mountain, where summer days can soar past 100°F, painting the landscape in shimmering heat waves that dance across the sagebrush. July brings the quintessential desert camping experience, with cool 50°F mornings perfect for coffee by the river before temperatures climb toward their century mark. Afternoon thunderstorms occasionally sweep across the canyons, transforming dry washes into temporary waterways. When winter arrives, it blankets the higher elevations in snow, creating a stark and beautiful contrast against the red rock formations while the campground itself remains accessible for hardy cold-weather adventurers.

About Split Mountain Group Campground
Nestled along the banks of the legendary Green River at 4,800 feet, Split Mountain Group Campground offers a front-row seat to one of nature's most dramatic geological performances. Here, beneath the towering presence of Split Mountain's ancient cliffs, modern adventurers find themselves camping in the shadow of prehistory. The nearby Split Mountain Boat Ramp provides direct river access for water enthusiasts, while the fascinating Quarry Exhibit Hall invites visitors to step back 150 million years and walk among the fossils of earth's ancient giants.
Split Mountain Group Campground caters to group camping with sites that accommodate tents and RVs. It operates year-round, with different amenities available during peak and offseason.
Historical SignificanceThis remarkable landscape has captured human imagination for millennia, from the ancient Fremont people who left their mysterious petroglyphs on canyon walls to the hardy homesteaders who tried to tame this wild country. Today's visitors can explore Josie's Cabin, where one remarkable woman lived alone for decades in this remote wilderness, or follow petroglyph trails to discover rock art that has endured for centuries. But the true stars of Dinosaur National Monument are the fossilized remains of creatures that ruled this land long before humans arrived—massive bones embedded in cliff faces that tell the story of a very different world.
Weather and SeasonsExperience the full drama of high desert seasons at Split Mountain, where summer days can soar past 100°F, painting the landscape in shimmering heat waves that dance across the sagebrush. July brings the quintessential desert camping experience, with cool 50°F mornings perfect for coffee by the river before temperatures climb toward their century mark. Afternoon thunderstorms occasionally sweep across the canyons, transforming dry washes into temporary waterways. When winter arrives, it blankets the higher elevations in snow, creating a stark and beautiful contrast against the red rock formations while the campground itself remains accessible for hardy cold-weather adventurers.
ElevationPerched at 4,800 feet above sea level, the campground occupies a sweet spot in the high desert ecosystem where the Green River has carved its patient path through eons of rock. From this vantage point, campers enjoy commanding views of Split Mountain's dramatic facade—a geological masterpiece where the river literally splits an entire mountain in half. The elevation provides relief from the intense heat of lower desert regions while still maintaining the stark beauty and clear skies that make this landscape so memorable.
Natural Features and SceneryAncient Fremont Cottonwoods spread their gnarled branches along the riverbank, offering precious pockets of shade in this sun-drenched landscape. Between these desert patriarchs, aromatic sagebrush fills the air with its distinctive scent after rain. The star of the show remains Split Mountain itself—a testament to the unstoppable force of water over time, its heavily eroded faces revealing millions of years of geological history in colorful layers. The Green River flows past in its endless journey, its waters reflecting the changing moods of desert light from dawn's first glow to sunset's final flames.
Geological RegionSet within a remarkable semiarid landscape where elevations sweep from 4,700 to 9,000 feet, the campground occupies a unique position along the Green River corridor. This is high desert country at its finest, where Fremont Cottonwoods cluster along life-giving waterways while hardy sagebrush dominates the uplands. The defining feature remains Split Mountain—a geological wonder where the Green River has performed the seemingly impossible feat of carving directly through a mountain rather than flowing around it. This dramatic landscape tells the story of immense geological forces, ancient seas, and the patient work of wind and water over millions of years.
