I'm looking to plan a trip to Lake Tahoe next summer. Is the lake warm enough for swimming? Perhaps rent a kayak/hang out at the beach. I'm not a skier and casinos aren't my thing, either. Basically just want to relax/visit a nice spa/take in all the scenic beauty that is Tahoe. I enjoy shopping. Should I look at North or South Tahoe? What is the difference between the Nevada/California sides? Thanks for any help you can provide.
