It was bordered on the west by Lycia, the north by Pisidia, the east by Cilicia and the south by the Mediterranean Sea. Its two principle cities were Perga (see note 1 at this verse) and Attalia.

Note 3 at Acts 13:13: The scriptures do not give John Mark's reasons for departing from Paul and Barnabas. We can tell by Paul's reaction in Acts 15:37-39 that Paul didn't consider Mark's reasons for leaving as being very good.
