Ok, found all the leaflets my daughter has kept from our 09 holidays to Side...why she is keeping leaflets I don't know
Anway, 'Magic Valley' tours offer a 1 day or a 2 day trip to Pamumukale. These are advertised as HB, and the cost is 1 day €25, 2 days €35.
Trajanus tour offers the same as above (TL prices are 55TL and 75TL for 1 and 2 days).
We have two different leaflets for Ora Tour. They are offering a two day HB trip...however 1 leaflet says €25 and one says €35.
Selale Tour (a lovely man calling himself George gave us this leaflet) offers a 1 and 2 day HB trips. 1 day is €25 and 2 days is €30.
Correct Tours says it is €25, but doesn't specify how many days.
Ora tours is giving prices in Sterling. £30 for 2 days, £22 for 1 day.
Ok, these prices are only guides, they were given to us in July and October, they might be higher or lower this season. The one day tours all leave at or before 6am, the two day tours tend to leave Side at around 8-9am. They mainly seem to leave on Wednesdays and Saturdays.
So, it is possible to do a day trip, but it will be a very early start, a late arrival back, a lot of travelling, and possibly not much time once you get there. Hope I've helped.
