Bus travel is another popular and affordable way to get around. Buses generally offer free Wi-Fi access, comfortable seating, onboard restrooms and reclining seats with headrests for trips between major and smaller cities. The bus companies connect major cities with smaller towns and virtually run around the clock, giving you the option of enjoying the daytime views or relaxing during a nighttime trip. You can bring your own food and beverage onboard. You can usually save money by purchasing your tickets in advance.
(Note: if you are from New Zealand, you will need an ESTA or a travel visa to enter the United States)
Some major bus companies:
Travel by train
Get on aboard as the conductor guides your train through expansive prairies, rugged mountains, spectacular city skylines and quaint little towns. Trains are an ideal way to see the United States without the stress of worrying about directions or getting lost.
Amtrak is the primary train service in the USA, offering service to 46 states and Washington, D.C., with 500 destinations along its 34,000-plus-kilometer route system. Most trains offer wide seats with ample legroom, complimentary Wi-Fi, restrooms, food and the ability to get up and stretch your legs.
For longer distances, sleeping compartments are available. Try Amtrak’s California Zephyr, which follows the trail of the pioneers and gold prospectors who made their way out West, traveling across seven states of magnificent landscapes. Or climb aboard Amtrak’s Vermonter and enjoy the historic towns, white-steeple churches and charming countryside of New England. Amtrak offers handy guides and podcasts to provide information about points of interest on your journey. Amtrak passengers can carry on two bags at no charge. The cost for each additional bag is $20.
