Very much depends where you are (aka which country's government you're under) and what scale you're talking about. Local travel within national borders is unrestricted pretty much everywhere. More locally, some regions may ask you to isolate upon arrival but they won't turn you back. International travel is still happening but the volume is very very low. Besides, most countries you could get to would ask you to isolate for a long period anyway, so unless you're traveling and plan to stay there's really no reason to go anywhere
