In 1969, Emerald Bay was designated a National Natural Landmark for its brilliant panorama of mountain-building processes and glacier carved granite. The natural beauty, geology and history of this unique island make it one of the highlights of any visit to the Lake Tahoe area. The park features Vikingsholm, one of the finest examples of Scandinavian architecture in the western hemisphere. The "Tea House" on Fannette Island, the only island to be found in all of Lake Tahoe. Emerald Bay was designated an underwater state park in 1994. It is the resting place for many boats, launches and barges used in the lake before the turn of the century, during the heyday of Emerald Bay Resort and used in the construction of Vikingsholm. Summer temperatures range from about 75 degrees during the day to the low 40s at night, and winter temperatures average from a high of 40 to a low of 20 degrees. Dogs are allowed in the park, but they are not permitted on the trails, on beaches, or in the Vikingsholm area.
Steep walking at times. Not recommended for anyone without physical stamina. Lots of people had to stop and rest and catch their breath going back to the top to finish. Emerald Bay itself is beautiful and picturesque. Lots and lots of people. Good luck finding a parking spot.
