We walked in the sun from the St Andrews hotel through the town to the park. It was generally clean and tidy with several people either sweeping leaves up or planting shrubs. Formal pools, and gardens, bandstands and summer houses, except for the pond herons and magpie robins, we could have been in any park in the uk. The only downside was the amount of plastic rubbish in the stream, which in truth was only visible because we where chasing birds. Well worth the 300rp charged to foreigners.
An hour is plenty of time and the walk through the town is fascinating and well worth the time in itself. If you like birds then you will spend longer.
