public bus to Valley of the Temples from Porto Empedocle?

If you Google "Bus Porto Empedocle to Valley of the Temples" you will get numerous hits. I'm reluctant to assume any of those sources is totally up-to-date and correct since I've never been to that part of Sicily, but there definitely seems to be bus service of some sort.

There is a bus to Porto Empedocle, I don't remember if it stops at the Museum or the archeological site; worst case scenario you would have to backtrack to the bus terminal.

I don't know what a pubic bus is. Whatever it is I presume it's sexy.

Anyhow, Autolinee Licata provides bus service from Porto Empedocle to Agrigento

Select: Linea Agrigento - Porto Empedocle (con diramazione per Villaseta)

then from Agrigento go to the valley (check instructions below):
