We recommend flying into Reno-Tahoe International Airport.
You will have to drive from the airport to Tahoe! So find a flight buddy and carpool with them, or plan to rent a car from the airport. It is a 45 minute drive, BUT we promise it's a beautiful one!
We'd recommend hanging onto your car for the weekend just in case you want to explore hikes, camp sites, and other to-do's around the lake.
