If you’re planning to travel to the United States, here’s what you’ll need to know and expect if you want to visit during the Covid-19 pandemic.

There are awe-inspiring landscapes (Alaska, Utah and the Maine coastline) and world-renowned city breaks (New York City, Las Vegas and Los Angeles).

There’s cultural variety (Boston, Memphis and San Francisco) and delicious food (Chicago, New Orleans and Charleston).

Finally, it has some of the world’s best road trips (California Highway 1, Route 66 and the Blue Ridge Parkway).

The United States no longer has any Covid-related travel bans in place against specific countries.
