There are a few ways to reach Vikingsholm on Lake Tahoe's Emerald Bay. One is to take the mile trail from the Vikingsholm parking lot. It's a steep trail that is about a mile long. But on the way back to the parking lot, you will have to hike straight up for a mile. The second option is to take a boat (which allows visitors to also visit the teahouse on Fannette Island on the way.)
The third option is to take the 6 1/2 mile Rubicon Trail which connects DL Bliss State Park and Emerald Bay State Park
The route from Emerald Bay State Park (the highest point of the trail) down to Vikingsholm offers a virtually uninterrupted view of Emerald Bay. As you hike down, you'll see that each view is a new vision of beauty. But there really are no bad views of Tahoe.
This section of the trail is the newest portion of the trail and doesn't exist on many older maps.
