The park of Estació del Nord hosts a full-day event dedicated to the practice of yoga and its life principles. The programme includes yoga classes (kundalini, ashtanga, hatha, vinyasa, etc.), meditation, conferences given by expert teachers, conscious theatre (artists dedicated to the practice of yoga and meditation stage reflective works with highly philosophical content that can elevate our conscience), a live performance by the musician BhaktiYoga and a fair where you'll find all manner of products related to the practice of yoga and a healthy lifestyle. If you're peckish, throughout the day you'll find stalls with vegan snacks and at lunchtime, tuck into a big communal meal.
Yoga Day is free, but if you want to make a voluntary contribution, it'll be gratefully received.
