When in the jungle town of Ubud, be sure to do a yoga class. They are relatively inexpensive and are a great experience. We did ours at the renowned Yoga Barn. The studios are open air and all you can hear is the birds and the wind. A great experience in such a spiritual place as Ubud, and it was just what we needed after long days of travelling. They also have a cafe there for healthy snacks and refreshments.
