The honest answer has two parts: how long the walk takes, and how long you will actually stand still.
Moving time from the Upper Gate to the Lower Gate, downhill, stopping for nothing, is about fifty minutes. Everything above that is looking at things.
What each amount of time gets you
Ninety minutes. The walk, three or four proper stops, photographs at the library and the theatre. No Terrace Houses. This is what a coach excursion gives you and it is not a disaster — you will have seen the shape of the city.
Two hours. The same, plus the Terrace Houses, at a pace that never quite relaxes. This is the most common independent visit and it works.
Three hours. The walk, the Terrace Houses properly, twenty minutes sitting in the theatre, the Experience Museum, and time to read the panels rather than photograph them. This is the first number at which Ephesus stops feeling like a queue.
Four hours or more. Now you can go back up. The upper city, the Church of Mary at the bottom, the stadium outside the Lower Gate, a second pass along Curetes Street when the groups have moved on. Very few people do this and it is the best version of the day.
Rough walking times, downhill
| From the Upper Gate | Minutes |
|---|---|
| Odeon and the upper city | 5 |
| Head of Curetes Street | 14 |
| Temple of Hadrian | 19 |
| Terrace Houses entrance | 21 |
| Library of Celsus | 28 |
| Marble Street | 33 |
| Great Theatre | 38 |
| Harbour Street | 44 |
| Lower Gate | 50 |
Add forty-five minutes if you go into the Terrace Houses, twenty for the Experience Museum, and ten to fifteen if you climb the theatre.
What makes it take longer than you planned
Heat. In July and August everything above takes about a third longer, because you stop in shade you did not plan to stop in. See best time to visit.
The crowd. Between ten and one, the narrow parts of Curetes Street and the doorway of the Terrace Houses back up. You will lose ten to twenty minutes to other people's photographs.
The theatre. People go up further than they meant to, then come down slowly because the steps are high.
If you are on a ship
Your constraint is not the site, it is the return margin. Work backwards from all-aboard, subtract the transfer both ways and the margin your ship demands, and what is left is your real number. It is usually smaller than the excursion implies. We have done the arithmetic here.
Is two hours enough for Ephesus?
Yes, for the site itself and one extra — either the Terrace Houses or a climb into the theatre, not both at a comfortable pace.
How long is the walk through Ephesus?
About a kilometre from gate to gate, roughly fifty minutes of moving time downhill without stopping.
How much time do cruise excursions give you at Ephesus?
Usually around ninety minutes on the ground, out of a four to five hour excursion. The rest is transfer and the return margin.
