Only worth it if:
-There is no one else there (weekdays).
-The weather is good (heaps of snow but no wind, seriously no wind!)
-You find a much cheaper way up and down the mountain (maybe organising a transfer back to your hotel)
The resort here is incredibly hard to get to without taking a guided tour or taxi. My girlfriend is Turkish so we thought there would be no problem working out how to get up the hill. We stayed in Izmit because the hotel was much cheaper (a third of the price) and nicer than The Green Park Resort. We found a bus going to Masukiy easy enough for 3.50TL each but then the only way up the mountain was a 60TL taxi ride. We searched around but with no luck, so we committed to a taxi ride.
The tickets were expensive at 80TL per person plus a 30TL deposit on the card. (Uludag is much bigger and only 70TL).
The mountain only had one 2man chair lift and the T-bar (at times) running that day. It was a Sunday and there were way too many people for only 2 lifts; about 40min waits. The runs were very short for both lifts. There was plenty of powder but virtually no access to it, so we had to climb a few hills to get any. The snow was good though, and had the top 3man lift been open I'm sure the runs would have been good. They system looked pretty old though and damn, it was cold; get some bubbles please.
When we left we thought we could ask the resort about getting up and down the mountain for the next day. They were very rude but they told us that the only way was by taxi and that was how all their guests got here. (It's 100TL from Izmit.) We decided not to pay that and instead found a tour group which had a few spare seats to ride down with. They even dropped us to our hotel for free. But the resort was a real let down.
I decided to ring all the hotels at the base to see if they could transfer us up the mountain the next day but the best I could find was 50TL for 2 people, one way. So we moved on. At these prices you might as well go boarding/skiing in Europe.
Per person 2 x 3.5 = 7 for the bus, 2 / 60 = 30 for the taxi, x 2 for both ways = 60. Then lift ticket at 80TL.
Total = 147TL or 53 Euros.
Frowny Face.
