We are trying to decide between doing the drive after dark, to arrive in Nafplio at night, or to spend the night in Ermioni and drive to Nafplio in the morning. If it is a scenic drive, perhaps being able to see it in the day would be worth staying in Ermioni 1 night? Suggestions appreciated! Thank you
It is a very nice drive during the day.
There are several routes you can take depending on how fast you went to get to Nafplio and how much you want to see.
You can use Google Maps to see various routes you can take and how long each route it will take.
FYI: Driving at night in an unfamiliar area can be challenging so I would recommend some type of Navigation System even during the day.
I use Google Maps when I am in Greece and for the most part does a good job.
