The Palatine is the most important of the seven hills of Rome, chosen by Romulus to found the city and later turned into the site of the Palaces of the Emperors.
The hill is accessible with the same ticket of the Colosseum, and, in my opinion, it is the most important of the 3 sites included: Colosseum, Roman Forum and Palatine.
That's because you can see the entire archaeological site from a high point, as well as the whole city.
The best preserved part of the palace will be the so called 'Stadium' which was really the personal chariot races track of the emperors, part of the Domus Augustana built by the Emperor Domitian, for his private quarters.
From the same palace, you'll have the chance to view from a high
On the other side of the hill, from the Domus Tiberiana built by the emperor Caligula and later transformed by the Pope Paul III Farnese into a botanic garden called 'Horti Farnesiani', you will find the best view of all, over the city of Rome and the Roman Forum.
If you come from the Colosseum, you will be able to access the Palatine hill from via di San Gregorio, just behind the Arch of Constantine or from the Arch of Titus.
In spring, I took my mum up on the Palatine, I brought some panini (sandwiches) and had a great picnic on the benches of the Horti Farnesiani. So you can do the same if you like. Don't get too complicated, don't bring too much staff, the guards might not appreciate your professional picnic style. Remember that you are in a 2000 years old archaeological area, in any case.
There is not a cafeteria on the Palatine hill or in the below Roman Forum, but you will be able to find public fountains (called by the Romans, big noses) if you are thirsty. The water is fresh, always running and safe.
If you are lucky as my tourists three days ago, you will meet black rabbits in the bushes of the Horti Farnesiani.
