I'm a fan of Lake Las Vegas, and I'm a fan of paddleboarding. So peaceful and you get a little bit of a workout before you go relax by the pool at the Westin. It's just a really fun way to spend an hour of your day. It's definitely easy to learn if you have never tried it. I need to try the paddleboard/yoga one of these days.
I took away a star because the staff isn't ultra friendly, and it's a bit over-priced, compared to some other places in other cities.
