Try yoga for free this summer thanks to these four Wanderlust: Yoga In The City events.

Yoga classes can really add up—I've seen prices as high as $35 per class here in New York City. Luckily, there are a number of free events that take place in cities around the country every summer to help everyone take a breather.

If you happen to be in the New York City area on Friday, June 21st, don't miss Solstice in Times Square: Athleta Mind Over Madness Yoga. Join thousands of other flexible friends in an enormous crowd of New Yorkers and visitors alike, all trying to find their inner peace in one of the busiest, loudest, most crowded places on earth. The event takes place all day and you can score freebies like gift bags and yoga mats (given to the first 1,500 participants). Stick around between classes for soothing musical performances, free giveaways, raffles, and a fashion show by popular yoga clothing company, Athleta.
