just checked
http://www.onemap.gov.sg & key in "petain road". after getting off from Exit H or I at Farrer Park Mrt Station, walk towards Kitchener Link, cross it. If you do not want to walk along Serangoon Rd pavement to face heavy traffic, walk towards back lane between row of shophouses nbr 430 to 452 on your left & just completed Studios@Marne. Then turn right to Candy Land. In the olden days, land occupied by the present Studios@Marne was once a brothel & a welding shop.
Another brother has mentioned walking along Kitchener Link opposite City Square Mall loading/unloading bay & step down to the drain & walk a short distance, then up a stretch with a makeshift altar near a tree. You then start with Hse 24 on your right & Hse 17 on your left in descending order. Avoid this drain route if it is raining. Cheong safely!
