Ephesus must be one of the most famous archaeological sites in Turkey (if not Europe). The good news is that it is only about two and half hours drive from Gumusluk Villa. The slightly less good news is that it is very popular and in peak season several coach loads of people converge on it every day.
The Ephesus site is quite extensive and has its own car park. The latest addition is the excavation of a group of town house near the library. You have to pay an additional entrance fee to see this new excavation – but it’s well worth it.
It is quite possible to arrange a coach trip from Bodrum (they will even offer to collect your from Gumusluk). Often these trips involve a night’s stay in a 4 star hotel (please note they are very small stars) and a stop at the other main tourist site in the area – Pumukkale. One of our first guests at Gumusluk villa took one of these trips; they had to be up at 6am in the morning. At least they thought they would arrive at Ephesus before the coach loads of other tourists; they had not considered the necessity of visiting the Gold Centre or was it the Carpet Village? (Perhaps that was on the return journey?). They arrived at Ephesus at midday in the heat of the day with all the other coaches…
Yet a trip to Ephesus is easily organised by yourself; either by hire car or by using one of the many coaches that leave to Selcuk from the coach station (next to the Dolmus station) in Bodrum. When we first visited Gumusluk 20 years ago we made the journey by coach and stayed over night in Selcuk, taking a taxi to Ephesus early in the morning – avoiding the crowds and the mid day heat
If you are planning the trip yourself, then we would recommend that you stay in a quaint little village called Sirence in the hills above Selcuk. It is very picturesque and has much more charm than Selcuk. We can recommend a boutique hotel in Sirence (http://www.nisanyan.com/); it has main bedrooms at or near the hotel and a wonderful a la carte restaurant (not too expensive). Alternatively it has village rooms for those on a budget; you can still book a meal and walk up to their restaurant in the evening.
In fact if the villa is not available for all the time you require, you might consider a couple of days at Sirence / Ephesus and then moving on to Gumusluk; Ephesus is only an hours drive from Bodrum / Milas airport.
