Comhairle nan Eilean Siar, along with Caledonian MacBrayne, Police Scotland and the Stornoway Port Authority are encouraging travellers to make bus and ferry bookings well in advance of travel.
Caledonian MacBrayne have already announced that foot passengers require a booking for the 16th-24th of July due to the high volume of passengers expected on islands ferries for the Hebridean Celtic Festival.
Councillor Uisdean Robertson, Chairman of Transportation and Infrastructure Committee at Comhairle nan Eilean Siar, said: “We are delighted that so many people are coming to visit the Western Isles over the summer and we are thoroughly looking forward to welcoming them.
"The week of the Hebridean Celtic Festival will be a particularly busy time, with Ullapool to Stornoway and other ferry services likely to be at full capacity and we are keen to avoid unnecessary congestion and delays. We would urge passengers travelling by car and by foot, to make sure they make bookings well in advance and also check in early at the ferry terminals.
“It is also essential for those intending to use the bus service between Ullapool and Inverness to pre-book with Scottish Citylink on their website or call 0141-352-4444 at least 48 hours prior to travel to avoid disappointment.”
