Take the time while traveling to try something new or experience the joy of doing something that you love in a different setting with a different teacher.
There are many lovely yoga studios in Cape Town and some like Yoga Life offer great deals to people on holiday. another great studio is The Shala. There are also a number of short yoga retreats, which is a great way if you are traveling alone to meet new people and most are set somewhere beautiful. All of them are suitable for any level of yogi even beginners. The yoga will meet you where you are :)
