East Boulder Trail – Gunbarrel Farm/ White Rocks Trail

The open space and White Rocks Trailhead provide access to the same area from two different directions. In the north, the open land rises on a high prairie bluff and is one of the best places in the area to find nesting Grasshopper Sparrows in summer, along with the likes of Western Kingbird, Horned Lark, and Blue Grosbeak. Traveling south, the trail drops down to cross the creek, where Tree Swallow, Warbling Vireo, and Bullock’s Oriole nest. Near the White Rocks Trailhead, eastern birds like Orchard Oriole and Least Flycatcher have sometimes set up shop, alongside southwestern species such as Black-chinned Hummingbird and Bushtit. Please note: dogs are not allowed at the White Rocks Nature Preserve.
