A few tips for those who are going SBWR:
1. On Sundays and public holidays, if you are going by public transport, take bus 925 from Kranji MRT which comes every 20mins. Taxi fare from the MRT is $5+. On other days, the bus stops short at the Kranji Dam carpark.
2. On weekends and holidays, the hides may not be suitable because there are bound to be other people around who may not keep as quiet or still as you.
3. Go early (<0830hrs) for free entry. Also free on weekdays.
4. Look out for wild boars near the entrance. Another subject to shoot !
5. A pair of binoculars is very useful for spotting and identifying the birds.
