Tyre (Arabic: Sour) is in a city in Lebanon.
You can get around the small city of Tyre by taxi, on foot or by local transportation. Taxis are pretty cheap and some are even comfortable to travel in.
Traffic is typical Lebanese - if you want to go, you must go regardless of the 'western' way of thinking in the traffic.
If you can't find a taxi, even some locals can offer you a ride inside the city, if you ask nicely.
The main hotel in the city is located on the beach with minibusses departing towards Beirut just a short walk away.
