We will hike the loop trail (2.3 miles) at Olompali and look for the last of the Milk Maids and Shooting Stars. We will see Indian paintbrush, seven species of ferns, the California state lichen, lace lichen and the California state grass, purple needle grass. We will also see the rare Napa false indigo shrub, California fescue grasslands, and 5 species of oaks including blue oak and Oregon white oak. The trail is relatively level with a somewhat steep part at the beginning.
