Just up Highway 431 a bit, you can catch the Tahoe Rim Trail. While it's high up, you don't gain much more elevation but have a great view of the Lake. This trail goes on for miles so you can hike to your heart's content!
Just 15 minutes from Incline Village, Kings Beach has public beach access and lots of shops and restaurants. It's a nice place to walk around and explore near the beach.
Lake Tahoe is one of the most beautiful places in the world (in our humble opinion). Take a drive around the Lake and check out its beauty from lots of different angles.
