* You are short on time.
* It is summer and you don’t want to stay to long in the extremely hot desert.
* You prefer to take a tour and not go by yourself.
Then a tour, from Jerusalem or Tel Aviv might be the right option for you.
There are many companies that offer this tour. Some are cheap but provide really bad service with drivers that can’t speak English and no customer service.
I prefer to write about the good one and not to do shaming to the bad ones…
