I've put a marker where Dragon Beach is shown on the government map website. But the satellite view shows there isn't much of a beach left today. It looks as though most of it has been reclaimed for the dual-carriageway.
This 1963 annual report says it was located at the "13 3/4 milestone, Castle Peak Road"
This was a popular swimming beach, as it was the nearest beach to west Kowloon in the 1960s and 70s. A map dated 1979 (Hong Kong Streets & Places, Vol. 2) shows it being reclaimed. Today the nearest swimming beaches are out on Castle Peak Road, past Tsuen Wan.
I finally managed to visit this beach, and it looks like a good one to go back to with the family.
The beach is small, but the water was clean and there are lifeguards, a shady area under trees just above the sand, and clean changing rooms. One of the swimmers I spoke to said it gets busy on Sundays and public holidays, but otherwise it is quiet.
