The trailhead is west of Highway 93 at Thomas Lane, about 0.5 miles north of the intersection of Highway 93 and Eldorado Springs Drive. This trail is accessed from the south side of the parking lot.
South Boulder Creek West is accessed from the south side of the parking lot. This trail passes by tall and mixed grass prairie as it meanders west along South Boulder Creek. Its terminus is at the southeast end of the Mesa Trail
which provides extensive trail access along the foothills, including routes to the top of South Boulder and Bear Peak
These are excellent trails to explore the grassland ecosystem and the lower range of the ponderosa pine forest. Mule deer commonly graze this area in the early morning. Coyote and fox can also be observed. The area also provides hunting grounds for many of our local raptors. In early May, wild irises bloom in great numbers along the upper Big Bluestem trail.
