The first movie, i suppose?
5-6 i think.
Simba wasnt 1 year old when he left Pride Rock. And it takes about 5 years for a lion to grow a full mane. (and i read somewhere the lion king producers said so as well) So when he came back, he was about 5 years old. At the end of the movie however, he has a cub with Nala, which means some time must have passed. So i would say... 6 years?

Correct. Or perhaps even 7-years old, because on the commentary the creators say that originally they intented to add a subtitle "2 years later" after the first adult SImba scene.
