First, I know minimal korean, and I am a vegetarian who don't eat onion garlic, but dairy products is fine.
From Jamsil station Exit 5, walk till you see a signage says 7000 on one side, there will be a queue, and tell the driver you're going to Seorak Bus Terminal(1st Stop!) Try catch it at 1230pm (or even earlier for seats) to catch the shuttle bus(location to wait @ see 1st photo) to the village otherwise cabbing there is approx. 30,000 won. The bus ride approx. 1 hr, and wait for shuttle bus.
The Village, ABSOLUTELY BREATHTAKING. It is really an escape from the city, I was here in the winter so it was covered in snow. Clean and minimalistic room and tons of places to explore. (pst! The hand washing area have soap and lotion). For my friend and I, most of the signage are written in complete korean, they have icons at the side which is easy to guess. They specially printed an english schedule for us, however all the activities are completely in korean. It will be difficult to follow with your eyes close, but you're free to be yourself, so it wasn't much of a problem. Not many people can converse english here. Food is provided, which has Vegan options. However as a Vegetarian, many food had onion or garlic. It is not that convenient, however chef kindly fried an egg because I was just eating rice. Breakfast was okay, and they prepared plain porridge for me too! The people (everyone!) are super friendly! TRY THEIR SPA! For people who are openminded and love mindfulness
