Lake Ilsanjo Loop Professional Guide

Detailed Trail Description from our Guidebook

"In the 1930s, Joe Coney bought the land that is now Annadel State Park. In the 1950s, he built Lake Ilsanjo on Spring Creek and named it after himself and his wife, Ilse. Joe used the 26-acre lake as a hunting and fishing retreat for his friends. Lake Ilsanjo is now the highlight of the park, popular with picnickers, mountain bikers, joggers, equestrians, hikers, and anglers hoping to catch bluegill and bass. The lake is surrounded by meadows filled with wildflowers. This hike leads to Lake Ilsanjo from midway along Channel Drive. The trail circles the lakeshore and returns via the Richardson Trail, making a large loop through the center of the park. The Richardson Trail is an old ranch road shaded by redwoods and mixed oak woodlands"
