1 Best Sight in Puerto Vallarta, Mexico

On the nine-hour Tequila Express train ride, blue agave fields zip by as you sip tequila and listen to roving mariachis. After a distillery tour, there's lunch, folk dancing, and charro (cowboy) demonstrations. Make reservations up to a month ahead; from outside Mexico you'll need to use Ticketmaster, which adds an 8% surcharge.
