For hikers, the three-mile (5 km) Emigrant Trail goes between the two overlooks and lets you see part of the Oregon Trail.
Some visitors have tried to hike off-trail to the exact locations where fossils have been found. This is not permitted because the ground is unstable, and there are no uncovered fossils to see out there anyway. If you want to see fossils, your only option is to go to the visitor center.
When hiking at the national monument, look out for red ants, scorpions, snakes, ticks, yellow jackets, bees, and mosquitoes. Don't feed the squirrels.
Do not hike off-trail. Landslides are a risk, and there are no fossils to see out there.
