Ferry passengers arriving from today (Monday July 16th) to participate in Hebridean Celtic Festival must have a ticket before they arrive at Ullapool, according to an online warning this morning from CalMac.

The ferry company has already published a similar warning on their website for the period from Wednesday July 18th to Sunday, July 22nd, when ferries are expected to be at peak capacity. They’re insisting that even foot passengers must book ahead if they want to travel to or from Stornoway anytime this week.

A Tweet at 9.30 this morning  (Monday) says: “Due to high volume pf passengers travelling over for HebCelt Festival, advanced bookings for vehicles and foot passengers are essential. Call us on 0800 066 5000 to check availability and make a booking.”

An amended timetable is to operate on Sunday 22nd July to accommodate home-going passengers, with the 1pm sailing leaving Stornoway already having ‘very limited availability’. CalMac has warned on their website: “Please note, passengers may be refused shipment if they do hold an advanced booking.”

Tickets for the Saturday night of HebCelt, when Deacon Blue will headline at the main arena on the Castle Grounds, and whole weekend tickets are now sold out.

Call CalMac on 0800 066 5000 to check availability and make a booking.
