What is the best city to visit in USA?

I would recommend St. Augustine, Florida. It is the oldest city in the US

Boston, Philadelphia, New York, Charleston, Savannah, Newport, Honolulu......lots of others the US has so much to see and do. We have great cities to explore historical sites, museums, restaurants , and parks and great national and state parks to see wildlife and hike and swim..

There's so many great american cities that it's hard to pick. That's one of the great things about the usa - the big amount of cool cities with attractions, diversity, etc.

Some of the top ones to visit or live in would be New York, Los Angeles, chicago, Las Vegas, Miami, Houston.

San Diego is one of the nicest cities in the country. It's a major tourist destination and there are tons of things to do. With 70 miles of beautiful beaches, countless parks and gardens, major league and college sports, dozens of golf courses, world class museums, Tony Award winning theater, great cuisine, dozens of micro breweries, best weather in the country, high tech industry, major universities, and the best zoo in the world, it's my choice as THE place to live and play in the USA.
