If you're coming in to Carson City, there are several options you can take. First, if you plan to fly in, the nearest airport is located in Reno. You could in theory fly into the larger airport in Las Vegas, but that is several hours away by car, and if you're trying to make the most out of your visit and don't really plan to spend any time in Las Vegas, it just isn't worth it. Luckily, this website has an easy function which can help you book flights, as well as car rentals, located here. Because Carson City is so close to Lake Tahoe, that also means that is very close to California. Coming from the Tahoe region, you could take Route 395 and head North into the City. Another option would be taking Interstate 80 and then taking Route 395, but that would only work out if you were coming from the East. It's important to remember to have your arrangments made well in advance, so that if anything should come up you are already prepared. Try to have your flight booked a few months in advance if possible and check regularly to make sure the flight is still scheduled on time.
