@Tom Kellie we were very lucky. it was our first visit to the park and we went very early. we heard dogs barking away and join a photographer standing there. then he pointed out the otters to us.
when we returned for a second time, they had closed off that part of the park. apparently, all the busloads of tourists and some singaporeans had disturb a fair bit of wildlife there and the park decided to close off those areas. Sad for us, but glad for the wildlife.
That was considerate of the photographer to point out the otters. I truly miss the courteous, thoughtful behavior of most Singaporeans.
The last time I was in Sungei Buloh, it was on my 60th birthday, as I'd flown to Singapore to photograph Varanus salvator on my birthday.
Two older Singaporean photographers on a remote Sungei Buloh walking path very kindly pointed out to me a resting saltwater crocodile which I would have otherwise overlooked.

At the Sungei Buloh information desk I met a teenager from Yunnan, Kunming who is a student at River Valley High School in Boon Lay. Despite the more than four decade age gap, he's become a very good friend, keeping me regularly informed on life in Singapore, with wit and his fine street photography.
Thus Sungei Buloh has positive associations with me. I'm glad to know that smooth otters also like its wetland habitat.
