During the last centuries of the Bronze Age, in the Hittites tablets found in Hattusa, the Treaty Bo 86/299 which sets the boundaries of the kingdom of Tarhuntassa, a town that borders the sea is called Hawaliya.
Under Hattusili III, some debris of annals mention conflicts with the country of Lukka. The names mentioned are Hawaliya, Nata, Parha, Hauhassuwanda [...] idawanda, Utima, Wasuwatta and Haurputtawanna. A second battle shows that countries had been abandoned to men of Lukka: Walma, Wattaruwa, ..., ..., Nahita, Sallusa, ..., Sanhata, Surimma, ..., Walwra, Hawaliya, ..., Inassa.
In the Amarna letters, EA104 and EA114, Wahliya is mentioned twice:
EA104 "Message of Rib-Hadda : let the king know that Pu-Bahla, the son of Abdi-Asirta, holds Ullassa. They have Ardata, Wahliya, Ampi and Sigata. All cities are theirs. So the king may send an auxiliary force to Sumur [...] If you do nothing, then they certainly will take Sumur, and kill the Commissioner and the auxiliary force in Sumur. What should I do? I can not go myself to Sumur; the cities of Ampi, Sigata, Ullassa, Erwada are warring against me."
The modern Alanya, in the middle of the southern coast of Anatolia, on a peninsula formerly known "Alaiye" or "Alaya", is the most likely site.
My notes of veracity :
The Hittite city of Hawaliya is designated Waliyha in the Amarna letters: 4/5
The Hittite city of Hawaliya is the present town of Alanya: 3/5
