Vana Retreat Dehradun almost seems a contradiction – a forest touching it on one side, nestled between the city of Dehradun and the hill-station of Mussoorie. Over the years, the outside world has crept nearer to our 20-acre Retreat, and yet just inside its boundaries, one enters a different world. Vana is located peaceful forests of Mussoorie Road, Dehradun, offering best authentic traditions of wellness with Yoga, Spa and Ayurveda retreats and holidays.
