This uninhabited granite speck in Emerald Bay State Park is Lake Tahoe’s only island. It holds the vandalized remains of a tiny 1920s teahouse belonging to heiress Lora Knight, who would occasionally motorboat guests to the island from Vikingsholm Castle, her Scandinavian-style mansion on the bay.
Fannette Island is accessible by boat, except during Canada goose nesting season (typically February to mid-June). Rent boats at Meeks Bay or South Lake Tahoe; from the latter, you can also catch narrated bay cruises or speedboat tours.
