Advice for tourists: choose which cable car company you use and check the weather/wind forecast.
1 first options should be City Gondola with new/fast/comfortable ski-lifts but can be busy over weekends and holidays and you need a taxy to the base station. (2 succesive long high capacity gondolas to 2000m, 1 chairlift at 2000m, 2 T-bars at 2000.). They are very active on Facebook with many real-time updates for current weather (good job :)).
2. the 2 succesive old cablecars to 2000m plus one new chairlift 1400-2000m and one old chairlift at 2000m are less crowded but les comfortable with less capacity but they cover almost the same area and they collect you from the city center.
The skipass is not the same (not yet, we hope...).
Apart from the nicely prepared runs this place can be great for off-piste skiers with a decent variety of open and tree runs.
What a big disappointment. I have made the big mistake to visit Sinaia during the New Year vacation on 02 January 2020. This was enough to ruin my whole vacation. From what to start and with what to finish?
I took the train from Braşov. One hour distance but the train was so full that you could not move. Of course, no sitting. You need a taxi to go to the gondola. And there is the big trick in Sinaia. There are two companies exploiting the mountain. The ridiculous thing about this is that the ski center had only 6-7 pistes posted. Despite the so small size of the ski center there are two companies with different tickets. This means you cannot ride with the ticket of the one company to the lifts of the other company. And, of course, no sign in English. Unfortunately, I took the lift of the company with old infrastructure. I waited to take Sinaia Telecabina 40 min. There are two levels. From Sinaia to 400 and a second Telecabina from 1400 to 2000. Alternatively, from 1400 you can take a chair with no queue.
They say that Romania is cheap for skiing. Well, I paid 90 lei = 18€ in order to ski one red piste! I was obliged to take 22 lei= 5€ for a single ride with the lift of the other company. But I could not ski down. Otherwise, I had to pay another 22 lei for a second ride. So telling Romania is cheap for skiing is at least misleading. The tickets are so expensive for almost nothing. The interconnection of ski centers is unknown word in Romania. In Austria there can be 100 posted with one single ticket of 50€. What is better to pay 50€ for 100 posted or 35€ for 6-7 pistes? I thought Greece was primitive in ski tourist but after visiting Romania I realized there are even worse countries in skiing infrastructure. I would strongly discourage anybody to organize ski vacation in Sinaia especially during Christmas or New Year vacations.
This place has a lot of potential because of the altitude, and because it is very accessible by car or train, but also some drawbacks. It's very windy and you can find yourself able to ski 2 or 3 days in a week. Also the weather is mild in the recent years and the lower part is rarely working more than a few weeks in one season. There has been some investments in the last years including snow cannons for the ski area up on the mountain, a new 8 person gondola going up to 2100 m altitude, some good apres-ski. Overall, it's ok but could be better with proper management.
