Fodor's Review

Owing to the rarity of resources and the difficulty of this hike, park rangers don't actively encourage use of the trail along Specimen Ridge, but for the conservation-minded, it can be an exceptional experience. The world's largest concentration of standing petrified trees can be found here in the park's northeast region, southwest of the Lamar Valley. There are also many unusual fossils, such as impressions of leaves left behind on rocks. Access is via a difficult but rewarding 3.2-mile (one-way) hike.
