By ferry
Two identical ships, operated by NorthLink Ferries, ply the route every night. These are comfortable, modern vessels with good facilities aboard. The voyage takes between 12 and 14 hours, depending on whether there’s a call at Kirkwall in Orkney. The crossing can be rough in the winter months, but between May and September there’s usually very little motion.
On the ferry, the basic return fare in peak season (for example, August) is £72. That doesn’t include any form of accommodation but it’s possible to sleep on the seats or indeed on the carpeted floor in the forward lounge; an inflatable pillow will help. In fact, if you want to lie flat, those are the only options unless you’re in a cabin. There are also upholstered benches in the cafeteria, but it’s at the rear of the ship, above the engines, where there’s noticeable noise and vibration.
You can, however, add a reclining seat, which costs £3.50 each way or £7 return. For £18 each way, you can book a sleeping pod, which is a more sophisticated recliner in a separate, quiet lounge area, equipped with a charging socket for your phone. A shower and a toilet are available.
The most comfortable option is a cabin, and these are sold in the same way as hotel rooms ashore. You get your own ensuite shower and lavatory; all cabins have TVs and everything you need to make a cup of tea or coffee. In peak season, a two-berth cabin costs £124 each way and a four-berth costs £121 each way, but if you book with a friend in a two-berth, that’s £62 each (single) or £124 (return). Sharing a four-berth with three friends brings the cost down to £60.50 per person return. (In ‘normal’ times – before the pandemic – it was possible to buy a bed in a single-sex four-berth cabin, or indeed a two-berth, outside cabin, sharing with someone you didn’t know, but that option is not currently available.)
You do, of course, have to pay the passage fare on top of these cabin fees, so the total bill may be similar to the cost of an air ticket. One advantage of ferry travel is that there is no charge for changing your travel dates. Nor is there any cost saving in booking early; however, if you leave it late, you might not get the accommodation on board that you want, especially in the very busy peak season.
We’ve more to say about getting around Shetland below but, if you want to take your own transport, you can book a space on the ferry. A peak season return for a vehicle under 6 metres costs £254.
