From here admire the views of the Roman Forum and Nero's Circus Maximus where chariot races were held. Romulus and Remus were said to have been found on the Palatine Hill by the she-wolf who nursed and raised them. The last stop is a walk along the Via Sacra or 'Sacred Way', the main path through the Roman Forum that was used for triumphal processions. Tour ends at the temple which houses the altar where Julius Caesar was cremated.Do you want special access to the Colosseum's underground chambers and its third tier?For the first time in history, the Colosseum is opening its underground level to visitors. 2011 marked the public opening of the Colosseum's underground chambers for the very first time, as well as the Colosseum's third tier, which hasn't been open in decades. If you upgrade to the 8:30am tour, you'll get special access to both areas and see Ancient Rome the way no one ever has. You'll follow in the footsteps of the gladiators themselves as you explore the tunnels where they once prepared for fights and where lions and tigers were once caged. You'll also go up to the highest existing level of the Colosseum - the third tier, or terzo anello, as it's called in Italian. This third level of the amphitheater is opening for the first time since the 1970s. The view from the third tier includes not only a new perspective of the inside of the Colosseum, but also the surrounding Roman Forum and Palatine Hill. It's not to be missed.These newly opened areas can only be visited with a guided tour and must be booked in advance. To get this once-in-a-lifetime experience, you must book the 8:30am tour. Not only will you skip the long lines (which can last up to two hours) to enter the Colosseum, but you'll also beat the crowds and enjoy the Colosseum in the calmer hours of the morning. Tours groups never exceed 10 people. You'll also get an extra 30 minutes inside the Colosseum (3.5 hours total).
