Annadel State Park has rolling hills, woodlands, grassy meadows and Douglas fir covering 5,000 acres. The site is also known for its wildflowers (including buttercups, poppies, and mule ears.) The park features an outstanding example of northern oak woodlands. Lake Ilsanjo offers black bass and scrappy bluegill. Ledson Marsh features 130 species of birds, such as Cooper's hawks, great blue herons and the pileated woodpecker.The park is popular with hikers, cyclists, and equestrians. There are 35 miles of trails and fire roads, providing easy to moderate hikes. Cobblestone quarries in the area once supplied paving material for San Francisco; the abandoned quarries can still be found along several trails. Camping is not allowed in the park.
Summers are generally mild. Fog is often encountered near the coastline, with sunny, warmer weather more common inland in the foothills. Winters are generally cool with considerable precipitation. Wear layers of clothing to accommodate cool to warm temperatures and good walking shoes. Rain protection should be included at any time of year.
