I believe you are talking about FFXII?

If you are looking for a way to/through the Tchita Uplands, you must go through the Limatra Hills. From the Phon Coast (hunter's camp), head northeast through the Realm of the Elder Dream. Take the northernmost route to the Skytrail. Once there, find the Chosen Path (head eastward) and this will lead you to a save crystal, then the Highlands and further in the game.
