Pirgos to Patra is about 105km.

The modern city of Olympia is quite small, (perhaps less than 2,000 people?) but does have a few hotels.

Patra is about 200,000 people and is the major hub for the western end of the country. It's never impressed me as a charming place, but I suppose it has its attractions.

Nafpaktos across the impressive Rio bridge is a nice place to rest. East and north of there is Delphi.

The area is served by bus and rail. The rail line west of Athens goes to Patra, then down to Kalamata. In 2007 the timetables shows about 10 trains a day in both directions, with a time from Pirgos to Patra of about 2 hrs.
