They take you on a walking tour around the historical, ancient, colonial and modern centre of Yangon pointing out features that you might otherwise miss and giving you the real story of this fascinating city.
They meet every Monday and Wednesday (check for updates in case of wet weather) in the the car park outside Maha Bandoola Park (opposite City Hall) at 4:00PM. Check their website map here http://www.freeyangonwalks.com/#meeting-point
NOTE: During off season from June until August every year, they run Free Walk once a week only on Monday due to heavy rain and having less visitors in the country.
