During the brief periods of freedom from her long detention, Suu Kyi had always refused to leave the country, fearing that she would not be allowed back in.
Myanmar has seen dramatic changes over the past year.
In May, Suu Kyi and 33 other newly elected members of her National League for Democracy party took up their seats in the Myanmar Parliament, a leap in the country's progress toward democracy.
The government has also pardoned hundreds of political prisoners, begun negotiations with ethnic rebel groups and embarked on a series of economic reforms.
These steps have been welcomed by the United States, European Union and other governments, who have responded by easing sanctions on the country.

Before her departure on Tuesday, Suu Kyi was expected to meet with Indian Prime Minister Manmohan Singh who is in Myanmar.
Singh held talks with Myanmar President Thein Sein on Monday, signing agreements to strength trade and diplomatic ties.
Thein Sein, the former military official whose civilian government has instituted many of the country's recent political reforms, was also due to attend the World Economic Forum.
However, organizers said his appearance had been canceled.
