Ercolano, or Herculaneum is as fascinating as Pompei but smaller and easier to get around.
It was destroyed in the same eruption by Vesuvius but because it suffered the terrible onslaught of pyroplastic flow instead of ash fallout, a lot more was preserved for us to see 2000 years later.
You can see and imagine life as it was in those days, with beautifully decorated walls inside houses. Get up close and walk, stand, sit inside rooms that are almost untouched by time and feel like you are living in Roman times.
There are guides available but we took the audio version and found it very good. You can be anywhere around the site and just enter the number seen on the wall outside to get a detailed commentary of what you are looking at.
The site has good facilities, with café / toilets near the entrance / exit so you don't have to leave before getting some refreshments.
My wife and I love these historical places and found Herculaneum to be one of the most interesting sites we have been to.
A tip, if you are travelling there by the Circumvesuviana train, look out of Ercolano Scavi station as it's this stop you get off at. We made the silly daft mistake of looking for Herculaneum, missed our stop and had to go back a few stations.
Outside the station you just walk straight down the main road for about half a mile to find the entrance right in front of you.
Have a good trip.
