Lonely Planet review
Assuming it’s not cloaked in opaque mist, the valley views along paved Coaker’s Walk are superb. There’s no plastic allowed on the pathway, a rule flagrantly flaunted by locals, and a small observatory with telescope at the southern end. Start near Greenlands Youth Hostel or Villa Retreat – where stained glass in the nearby Church of South India (CSI) is stunning in the morning light – and the stroll takes all of five minutes. The 5km lake circuit is pleasant in the early morning when you can count the kingfishers before the tourist traffic starts.
