Are Guides Available At Olympia?

[Cahroozer]

We'll be traveling to Olympia via Katakolon in November. I see that transportation to Olympia is now easier with the opening of an inexpensive rail link.

 

However, we'd like to also have a guide for the site and museum. Does anyone know if guides are available, the way they are at the entrances to other historic sites, such as Pompeii?

 

Thanks for any information.
