Vipassana means seeing things as they are. In practice, it means long sittings where you pay close attention to sensations: the ache in your knee, the itch, the tightness in your chest. You observe them without fixing them, and you watch them change.
It is not relaxing. Expect long hours, boredom, a sore back and at least one afternoon when you wonder why you paid for this. That is part of the training. The method works because you stay with the unpleasant things long enough to see that they pass.
The days are structured and quiet. Every evening there is a talk, and you can ask a teacher privately whenever you need to, so you always know what to do next. This is a serious retreat. If you've never meditated, start with the Meditation or Guided Meditation retreat first.
What you leave with is a calmer relationship with discomfort, your own and other people's. Less reacting, more choosing. It's slow to describe and quicker to notice at home, usually in the middle of an argument you would have lost your temper in.
The valley, the food, the place
Long sittings are easier with something to look forward to afterwards, and here that is a walk through the valley, a proper meal, and a clean, comfortable place to rest. Food is healthy, varied and served on a regular rhythm. The group is serious about the work without being grim about it. There are small, welcome surprises along the way, because ten days is a long time to be sitting. The food is excellent, and vegetarian options are always available.
