This week is Festival Week on Po Toi, from Thursday 5 March to Sunday 8 March.
A revised Ferry Timetable applies for these four days, as given here
Not that there is much to see on Po Toi at the moment, this is usually the low point of the year (except summer), I went yesterday and saw very little.
Most of the thrushes have gone and I didn't see the Hoopoe.
I will go tomorrow, but to look for seabirds.
