Basically if you can think it and its an outdoor activity you can do it in Tahoe.
Tahoe has beautiful trails for hiking, biking, rock climbing, and nature walks.  You can start out from your lodging location or drive to a more secluded spot.  We have several golf courses as well as frisbee golf courses.  One of them is back at the Bijou park where we bout.

Our lake is one of the cleanest lakes in the world.  In most places around the beach you can see to the bottom, just like a tropical paradise.  Remember in early spring the water is snow melt off so be careful!

Most beaches have some sort of boat or board rentals.  The larger resorts around the lake rent water sports.

Have you tried Stand up Paddle.  We suggest South Tahoe Stand Up Paddle
