Hi - my wife and I are visiting Granada in mid October.
We are staying near Plaza Nueva and we don't have a car.
I can see on the official site that tickets are available.
Is it possible to buy the tickets and print them off at home on our own printer. ( we just want two adult tickets- not any concession tickets)?

If we get to the Alhambra with our own tickets  do we have to join the queues for entry? I’ve heard that the queues are long. Or can we just enter with our tickets.

Any advice would be welcome.

You don't have to print the tickets any more you can  show the screen of your smartphone.

Make sure you keep your phone charged. 

You only need to go to the main entrance if you have want to get a special concessionary ticket which could be for a handicapped person or a child.

By far the easiest way of getting into the Alhambra for most people is the Justice Gate. (Puerta de la juticia)

There is full information about how to get there here.

Most people could walk up the hill to the justice gate from Plaza Nueva but it is uphill.

If you don't think you can walk up the hill get on a C30 minibus. The bus stop is behine the statue at the end of Gran Via. 

There is more info about these buses here   You could also get on the C32 if it goes past near to where your accommodation is.
