Kilika Port

Kilika can only be reached by boat or airship. It was home to High Summoner Ohallan and a temple of Yevon.

Final Fantasy X
When you reach Kilika in Final Fantsy X it had recently been destroyed by Sin. This is the first time you witness Yuna preforming The Sending. The next day you go to the temple of Kilika to pray to the Fayth and also pray for victory at the blitzball tournament in Luca. There you meet the Luca Goers, another summoner named Donna and Yuna gains the Aeon Ifrit.

Final Fantasy X-2
Kilika had just been rebuilt after Sin's attack. It is now the Home of Donna and her guardian, Bartello.
