The beauty of yoga retreat is that as an asana, two do not exactly match. This is the task of describing what to expect when something is hard to come by.
I'd like to encourage you to do a little research when deciding where you want to go. If you have a studio you regularly practice, it's likely to be the most convenient for retired retreats by one of the instructors. The chances are you love the studio's energy, you will appreciate the retreat.
Most retreats offer one or two yoga classes and directed meditation every day. Generally, there are more optional options available. Depending on the location and time of year, everything is available from swimming, hiking, skiing, nutrition seminars, massages, fiery fires and Ayurvedic counselors.
Some resorts have televisions in their rooms while other retreats are outside or in cabins. Retreats are different in their rules, but I usually think you can be confident that the environment is one of peace and tranquility, so a party like a rock star in your room will not be a viable option. That is, if you have your own room. There are retreats in the ashram, where the hall is dormitory style. The price of retreat is generally a good indication of what the accommodation will be like.
Whether the five-star capricious or rustic and rural food is usually organic or locally grown. Your best bet is to always check who is responsible for retirement. She is reluctant to see pre-cooked meals to find out that her master is cleaned all weekend!
With the increasing popularity of yoga there are more and more yoga retreat today. Choose the one that suits you best and talk to people who have been before to better understand what you can expect.
