(California)
Emerald Bay State Park is a state park of California in the United States, centered on Lake Tahoe's Emerald Bay, a National Natural Landmark. Park features include Eagle Falls and Vikingsholm, a 38-room mansion that is considered one of the finest examples of Scandinavian architecture in the United States. The architect was Leonard Palme, who was hired by his aunt Lora Josephine Knight to design and build Vikingsholm. The park contains the only island in Lake Tahoe, Fannette Island. The park is accessible by California State Route 89 near the southwest shore of the lake. Emerald Bay is one of Lake Tahoe's most photographed and popular locations.
