I've tried nearly every yoga studio in the Madison area (Bliss flow, Inner Fire, the Studio, Dragonfly) and although these are all top notch places they don't compare to Perennial. Perennial's studio is hands down the most beautiful studio in Madison. The back wall is a huge window that opens up into protected prairie lands that are beautiful anytime of the year. What I like most about perennial however is their focus on yoga philosophy and spirituality. I feel with a lot of the other yoga studios in mMadison you get just Hatha Yoga (which you do get at Perennial too) but the classes don't go much deeper then that. Perennial has some very gifted instructors and they offers Bhakti, Ashtanga, Nidra, meditation and a plethora of different offerings for anyone looking to go deeper into their yoga practice. If you're a beginner or advanced and haven't taken a class here yet I would highly recommend it.
