"The loop through Los Posadas State Forest combines narrow trails, old fire roads, and a few sections of well- used service roads. It travels through an amazing number of habitats as it circles the headwaters of Moore Creek, including a rare Wine Country ponderosa pine forest, redwood groves, and arid chaparral.
Las Posadas State Forest is a small block of public land hidden away in the Howell Mountain area on the east side of the Napa Valley. Howell Mountain—a high, broad plateau—is home to the community of Angwin and Pacific Union College, a small university. Due to its high elevation and volcanic soils, Howell Mountain is also a distinct wine- making region, separate from the Napa Valley to the west and the Pope and Chiles Valleys to the east. Las Posadas is just east of Pacific Union College. The state forest was once a private ranch but it was donated to the state early in the twentieth century. The park contains the headwaters of Moore Creek, a tributary of Conn Creek, which in turn feeds into the Napa River." Read more
