How to filter taxonomy term in views from URL
The best way to do this is as follows:

Assuming you have fields in your content type for continent, country, and city: Add each of these fields separately in your view's Contextual Filters. You can leave them at the default settings for now.

Then, change your path settings for the page to one like such: destinations/% (the % will be replaced with your contextual filters).

After saving the view, you should then be able to visit a path such as destination/europe/france/paris OR destination/europe/france, granted you have content within those areas.
