Mycenae is a popular day trip destination from Athens. To give some scale to this map it is about 50km (30miles) from Corinth to Argos.

Mycenae is not a town, Mykines, a couple of clicks down the road is - and has a few hotels.

You can get to Mycenae by car and by train. You have about a 2km walk from the train station to Mykines. There must be bus connections as well, but I'm not familiar with that.

There is a lot of history in the area. Corinth has significant Roman era ruins. This area is the country of Hercules. He dealt with a big lion from Nemea, for example. Tiryns is a contemporary town with Mycenae and also has interesting ruins.

Nafplio is a good destination town, with an old fort and a nice waterfront. To the east of this map is Epidaurus, a town with a classic-era Asclepion (healing center) and a magnificent Theater.
