Although Uludag is Turkey's oldest and most famous, the piste is not well designed and some lifts were exclusive to some hotels even though I had a full resort pass - 65Lira for 1.5days in March.

The links between lifts and runs were not great and one has to make routes which is good but nothing compared to Europe. On a positive the snow is great, natural and real powder, you'll love the off-piste; but be warned the mountain gradient is not high, there are no black runs, maybe a few red and the runs are generally short; at most spend 3-4 days there.
However, it's not cheap, the hotels are expensive (even the basic ones) and at the weekend they double their prices, so negotiate and ask for an 'inderim'/discount and see where you go. Ski hire was 20lira per day in March for ski/pole and boots and private lessons were 60lira for 50mins.

I hope this helps and personally I'll ski in Turkey again, but at Palandoken in Ezurum in east Turkey which is a new resort and at 3300m high, it should prove more rewarding! We'll see :-)
