Poison Spider Mesa Trailhead

Poison Spider Mesa Trailhead provides access to some of Moab’s most iconic recreation, including the 16-mile Poison Spider Mesa 4×4 and mountain bike loop, the Golden Spike Route, and hiking trails such as Longbow Arch (1.1 miles one way) and Poison Spider Bench (1.3 miles one way). A short side trail leads to petroglyphs and a dinosaur tracksite where footprints from at least 10 carnivorous dinosaurs can be seen. This mix of off-road adventure, family-friendly hikes, and cultural and paleontological discovery is set against sweeping views of the Moab Valley, Colorado River, and La Sal Mountains.The Poison Spider Mesa dinosaur tracksite features theropod footprints — identified as Eubrontes and Grallator — preserved in limestone blocks that fell from the overlying Jurassic Navajo Sandstone. These tracks formed about 190 million years ago in fossilized pond deposits between giant sand dunes, offering rare insight into dinosaur behavior and movement. Nearby petroglyphs, carved by ancestral Indigenous peoples, depict human and animal figures and provide a fascinating glimpse into the cultural history of the region. Interpretive signage by the BLM explains the site’s significance and encourages visitors to respect and protect these fragile remnants from the past.Hours and SeasonsOpen year-round.
