Yongpyong reviews

From the beginning I was going to spend a weekend here but when there were no available rooms it became a day trip. It's probably luck for the system is not that big you'd like to be 2 days here.
Getting to Yongpyong from Seoul is easy. There are buses from the airport and from the city center. I took a bus from Jamsil station and they depart about 6 in the morning. The journey takes 2.5 hours.
Recommend to book bus ticket in advance to be sure of location if it is high season. The bus I went with was fully booked.
Once upon a time it's easy to find. At the foot of the main back there is a kiosk selling lift passes (approx 350kr / day) and also paying for rental equipment (200kr for "Premium" skis). Then you receive the receipt and pick up skis, boots etc. in a large building next door. Smooth!
Most of the slopes are very flat and quite short. However, there are a number of good right-handers (Gold) and left (Rainbow) in the system.
Off-piste opportunities are basically non-existent. Very dense forest next to the slopes.
You can ride the lift streets but these areas were closed when I was there.
The backs were good all day and although some slopes were "clean-cut" towards the end, it became relatively little puckles and never ice-cold. Very nice snow conditions!
Home runs buses every hour from 5 am. Again, good to book in advance.
