Next week is Festival Week on Po Toi, from Monday 3rd May to Friday 7th May.
This means half of Aberdeen will be on Po Toi, but mostly around the harbour. The compensation is a special Ferry Timetable with frequent sailings every day from Aberdeen to Po Toi. Here is the Timetable for next week.
Note that the ferry timetable for the two weekends 1st and 2nd May and 8th and 9th May is as normal for a weekend.
