Never mind the heat, here&rsquos a great opportunity for Delhi people to know more about the flora and fauna of the Asola Bhatti Wildlife Sanctuary. Delhi CEC (www.cecdelhi.org) will be holding two nature walks in May, at dawn and dusk to showcase Delhi&rsquos wildlife. An early morning three-hour walk, starting at 6.30 am will be held on May 15. A two-hour evening walk starting at 4.30pm will be held on May 29. Both walks will begin from the main gate of the sanctuary and cost Rs 350 per head. Do not forget to wear comfortable shoes and carry water.  A pair of binoculars will make the trip even more enjoyable.
