I do yoga 2-3 times a week so when I was planning on my trip to the French Quarter, I looked into which yoga studios were nearby. I didn't find any TOO close, so I was super excited to see a sign advertising yoga at the Cabildo - a 1 minute walk from my hotel!
The class was from 7:30-8:30am, which is way before the museum opens at 10am. The class was $12, which is way cheaper than what I am used to paying in NY so I was happy about that.
