Awesome place on North Lake Tahoe to rent paddleboards/kayaks. Get there early morning while the lake is very still or inquire about a sunset paddle. You don't have to make reservations but it is first come first serve if you don't. Paddle towards the east shore, it's so beautiful!!
Plenty to do here: Beaches, shopping, restaurants, bars. South Lake is about 45minutes from Reno.
They have an amazing spa here if you want to pamper yourself!
