Burlington International Airport: Rent a car at the airport; it is the genuinely practical option for Stowe. The drive is roughly 40–50 minutes via I-89 and VT-100, assuming normal conditions. There is no airport-to-Stowe rail link and public transport is limited; prebook a shared/private shuttle only if you will stay on the Village–Mountain Road corridor. Expect winter weather and holiday traffic to lengthen the trip.
Waterbury Amtrak station: Waterbury is the useful rail arrival point, served by the daily Vermonter. Stowe is about 10 miles north via VT-100: arrange a taxi or, better, collect a rental car for a roughly 15–20-minute transfer. Do not arrive expecting a dependable walk-up local bus connection, especially on weekends or in winter.
