Emerald Bay sparkles as a diamond within the jeweled landscape known as Lake Tahoe. Designated a California State Park in 1953 and a National Natural Landmark in 1968, Emerald Bay is one of the most photographed landscapes in the Sierra, featuring California's first underwater park, dramatic Eagle Falls, and Lake Tahoe's only boat-in camp. Vikingsholm, nestled within the southwestern edge of the bay, is a 38-room mansion that is a dramatic example of historic Scandinavian architecture. A small stone teahouse steeped in fanciful lore is perched atop Emerald Bay's Fannette Island. The Desolation Wilderness, established in 1969, is one of the most popular wilderness-designated areas in the United States. The geographic area of the wilderness is just less than 100 square miles, includes 130 lakes scattered throughout the alpine topography, and contains countless waterfalls and streams intersecting the hiking trails and granite landscapes.
