Any suggestions for a vacation in any US small town which has good public transport facilities.

Give us an idea of budget, season of the year, near an ocean, desert, mountains etc.
How big is your small town?
Where are you coming from?

Small towns in the us typically have terrible public transportation. Unless you mean small cities? Or something else? We really need to understand what you have in mind in order to answer this question.

San Francisco, New Orleans, Las Vegas, and Charleston are interesting cities that are easy to get around on foot or public transport. Key West may also fill the bill for you.

What time of year?
How long for this trip?
What are you interested in doing?
What are you not interested in doing?

First, agree, that small towns in the US typically have practically no public transit - the car is king.

Second, you need to give us a clue about:

When you are coming
Who you are
What your interests are/what you hope to accomplish (many small towns have very limited resources/activities)
What you consider a "small town" to be

Thank You every one, I should have worded it properly , I was interested in visiting something not so touristy / crowded.

Fargo.

Portland, Oregon.

But we are a car society. You won't be able to go outside the city limits.

Long Island, NY, east end, north shore or south shore. We have great trains and gorgeous beaches. But only go east-west on the trains - they don't go north-south. Then a short cab ride to towns. Avoid the crowded summer and it's great. May and Sept are beautiful. Shelter Island is totally bikable but no transit at all.

Mackinack Island, MI has no cars. DS was there recently and enjoyed it.

Sarasota, Florida.

The bus system will get you just about anywhere although you have to plan accordingly as they run once an hour on most routes, 1/2 hour on few major routes.

Bradenton, Sarasota and Venice plus all the islands, Siesta Key, Lido Key and Longboat Key.

How small? There are small towns in New Jersey which are easy to get to by public transportation and once there are completely walkable.
For example, Check out Red Bank or Princeton.

The USA is over 3000 miles (5000 km) across - there are thousands of towns that you could consider. Do you want west coast, New England, the south, mountains, ocean, hot climate, culture, etc,etc ??????

Contributors here have been trying to help you and have asked for more information from you in order to steer you in the right direction but you keep ignoring their requests. All we know is you want to visit a small town in the US that's not touristy or overly crowded and has good public transportation. As you've been told there are 1,000's of small towns, many so small you don't need transportation in order to get around.

Answer some of the questions and you'll get meaningful responses.

First of all - Long Island is not a small town. Most of it is suburbs of Manhattan - with the far east end primarily an upscale resort area. The population is between 3 and 4 million people.

Second - trying to navigate Long Island without a car is fatal. There are commuter trains into NYC - but other than that getting anywhere without a car is next to impossible.

Agree there is a lot to do on LI - but not something I would reco in winter - but you MUST drive and while there ARE some small towns the whole area is not at all small townish. And in season the traffic can be truly horrifying.

nytraveler - I absolutely disagree. Ever been out east? Apparently not. I can get around without a car.

Who mentioned winter?

I have out east at lot and it is very limited, except for the core of major cities, where you can get around without a car.

As with any place else (worldwide), it is not that difficult to get TO the small town you might be looking for, but it is certainly quite difficult to get around once there sans car (neither taxis, nor public transportation is abundant).

Of the smallish towns I know that are served by Amtrak train, Glenwood Springs has the best bus service. In peak season they have a bus headed for Aspen every 15 minutes.

There are a few things in GS that are walkable as well.

Hi TinaNY,

I was trying to think of a "small town" that fit the bill, and Key West, Florida with a population of about 25,000 souls was the one place that sprung to mind instantly in the US (although certainly the tourist population spikes up the population considerably). Other than the bus system shown below, there are bike rentals available that could get you most anywhere you wanted to go on Key West. (Honestly though I only used the public bus system to get from the Greyhound station to Old Town Key West; I mostly walked, biked otherwise.)

Have fun and hope you get some more suggestions! Daniel
