Great Divide Basin

The Great Divide Basin is a unique and remote endorheic basin in Wyoming, where the Continental Divide splits, creating a region where water neither reaches the Atlantic nor the Pacific. This vast, high-desert landscape offers a true wilderness experience for adventurous travelers seeking solitude and dramatic natural beauty.

Highlights & What to See

• Continental Divide Split: Witness the rare phenomenon where the Continental Divide diverges, forming a basin that collects water internally. This geological oddity is a must-see for geography enthusiasts.
• Red Desert: Explore the striking Red Desert, a high-altitude desert with colorful rock formations, sand dunes, and vast sagebrush plains. Keep an eye out for wild horses and pronghorn antelope.
• Boar's Tusk: Hike to the base of Boar's Tusk, a volcanic plug that rises dramatically from the basin floor. This landmark is a remnant of an ancient volcano and offers panoramic views.
• Killpecker Sand Dunes: Visit the Killpecker Sand Dunes, the largest active sand dune system in North America. You can hike or try sandboarding on the shifting sands.
• Historic Trails: Trace the routes of the Oregon, California, and Mormon Pioneer trails that cross the basin. Look for wagon ruts and historic markers that tell the story of westward expansion.

Suggested Time to Spend

Allocate at least a full day to explore the Great Divide Basin, but two days are recommended to fully appreciate its remote grandeur. The area is best visited from late spring to early fall when roads are passable. Start early to drive the rough, unmaintained roads and allow time for short hikes and wildlife viewing. Camping under the vast, dark skies is a highlight for stargazers.
