LacyHagerman Fossil Beds National Monument preserves one of the world's richest fossil deposits from the Pliocene Epoch, where families can explore actual fossil sites containing remains of ancient Hagerman horses, mastodons, and saber-toothed cats that lived 3.5 million years ago. The park's five-mile scenic drive leads to overlooks above the Snake River where kids can peer down at the very fossil beds where scientists continue making discoveries. Unlike other fossil parks that display replicas, Hagerman offers views of actual excavation sites where paleontologists have uncovered over 200 species. The Thousand Springs Visitor Center houses authentic fossil displays and explains how this area transformed from lush wetlands to today's high desert landscape.

Program Details
Best Ages for Hagerman Fossil Beds National Monument
Age ranges are suggested groupings — check at the visitor center for the official Junior Ranger booklet breakdown.
Ages 4–7
Young kids love seeing the massive fossil displays at the visitor center and spotting wildlife along the scenic drive. The overlooks provide manageable walking distances, though parents should supervise closely as there are no railings. Simple fossil identification activities typically work well for this age group.
Ages 8–12
This age group gets truly excited about the paleontology aspects and can handle more detailed fossil identification activities. They enjoy learning about how scientists excavate fossils and often ask great questions about the ancient animals. The hiking trails and overlook walks are perfect for their energy levels.
Ages 13+
Teens and adults appreciate the scientific significance of ongoing research and can engage with more complex geological concepts. They often enjoy the Emigrant Trail hike and connecting the area's natural history with westward expansion stories. Advanced participants may complete more comprehensive paleontology activities.
Planning Your Visit
Getting There
The Thousand Springs Visitor Center sits one mile north of Hagerman on US Highway 30 with adequate parking for larger vehicles. No entrance fees are required, and the park road stays open 24 hours though overlooks close at dusk. Facilities are limited along trails, so plan accordingly.
Van & RV Notes
Our 22-foot Sprinter fits comfortably at the visitor center parking area, and the park road accommodates larger RVs without difficulty. No overnight camping is available within the monument itself, but nearby state parks and private campgrounds offer hookups. The monument's open access makes it perfect for a day visit from your base camp.
Best Time to Visit
Spring through fall offers the most comfortable weather for outdoor exploration, with summer temperatures reaching the mid-90s. Winter visits are possible but trails and overlooks aren't maintained, and icy conditions can make walking hazardous. We truly love visiting in late spring when wildflowers bloom and wildlife is most active.
How Long to Spend
Plan a half day to see the visitor center exhibits, drive the scenic route, and visit both overlooks. Families doing Junior Ranger activities or hiking the Emigrant Trail should allow a full day.
Don't Miss
The Snake River Overlook provides stunning views down to the actual fossil quarry sites where Hagerman horses were discovered. Kids absolutely love the hands-on fossil displays at the visitor center where they can touch real specimens and learn how paleontologists piece together ancient ecosystems.
