Unst

By boat is the only way, there's no air service. From Mainland Shetland you first take the ferry from Toft to Ulsta on Yell, then cross that island to Gutcher, as described for Yell#Get_in. A day trip is simple by car but barely possible by bus - join an organised tour from Lerwick if you lack your own transport.
At queue in Lanes 1 / 2 for Unst. May-Sept the Bluemull ferry usually takes 5 min to cross from Gutcher to on Unst, M-Sa sailing every 45 mins or so, Su every 90 min to 2 hours, from 06:15 to 22:15. However five or six ferries per day follow a triangle: from Gutcher to Hamar's Ness on the island of Fetlar (20 min) then onward to Belmont, or the reverse pattern. Assuming you started from Mainland Shetland that day, your ticket is already paid; if you started from Yell it's £14 return for a car and driver plus £5.70 per passenger. Timetables to Unst from Oct 2019 are not yet posted.
The ferry terminals at Gutcher and Belmont are basic, just small waiting rooms with toilets and a timetable.
By bus you can get here from Mainland M-Sat. Leave Lerwick on Bus 23 no later than 14:00, to reach Toft for the ferry to Unst. Connecting Bus 24 crosses Unst for the ferry from Gutcher, landing at Belmont around 16:30. Bus 28 then takes you up Unst as far as Baltasound, Haroldswick and Saxa Vord.
This timetable is designed for day trips from Unst to Lerwick, so that residents can do what they need to in town and dash round the supermarket in time for the afternoon return north. It is mathematically possible but a fraught expedition to day trip by bus from Lerwick to Unst. You have to set off at 07:50, and if all the buses and ferries work out you can reach Belmont by 10:20 and the north end of the island by 11:00. You'd still be 3 miles short of Hermaness, and you need to head back at 15:30, with luck returning to Lerwick around 19:00. You'd be glancing at your watch the whole time and stressing about making your next connection, which is no way to experience Shetland.

The main road A968 is two-lane and well-maintained. The other roads are single track with passing places, also in good condition, but the last stretch of lane from Burrafirth to Hermaness is very narrow and steep. Watch out for stray sheep and ponies.
Bus 28 runs four times M-Sat up the main road from Belmont via Uyeasound, Baltasound and Haroldswick to Saxa Vord, with the late afternoon run being the best connection from Lerwick and therefore the busiest. A few more buses run part route. Those timetabled as DAR are Dial-a-Ride and have to be booked before 16:00 the previous day by calling +44 1595 745745. No buses reach Burrafirth or Hermaness: Haroldwick 3 miles away is their closest approach.
By bike as elsewhere in Shetland can be wonderful in good weather. It's utter misery in the winds and slashing rain, and with the clock ticking down to your vital ferry.
Bike hire is available from Saxa Vord Resort, see "Sleep".

• Belmont House near the ferry pier is a Georgian mansion that is closed for restoration as of July 2019. It may one day re-open as self-catering accommodation.

• Muness CastleFortified mansion or "fortalice" built in 1598 for Laurence Bruce of Cultmalindie (1547-1617), a terrible despot who had reason to fear his half-brother, the even more murderous and tyrannical Earl of Orkney. The castle survived attack by the Earl but burned down some years later. An inscription in Shetland dialect above the doorway prays for no one to harm the castle, in answer to which, it's now in the care of Historic Environment Scotland. It's not locked; there are torches behind the information board.

• Halligarth Woodland

  address: Baltasound
  A walled small area of trees, managed by the National Trust for Scotland. This would be nothing special elsewhere, but on this barren treeless island, this is a surprising place.

• Bobby's Bus ShelterWhat the Baroque Age did for the gilded palaces of Europe, Bobby Macaulay (born 1989) did for this bus shelter. When he began school, he'd cycle here and take the bus, leaving the bike in the shelter. In 1995 the Council intended to remove the shelter but he wrote to them explaining how essential it was. They changed their mind and refurbished it, adding a few comforts, and the improvement took on a life of its own. Volunteers and passers-by added a sofa, curtains, magazines, plants, soft toys and so on, even a phone and laptop computer. It's been styled in different annual themes: 2018 commemorated 100 years of women's suffrage in the UK, and 2019 is themed on "Fake Gnus". The sporadic arrival of the Number 28 is a bit of an anti-climax.

• is at first glance a barren rocky scree just north of Baltasound, 200 yards from the main road. But look closer, especially mid-May to early June, for the unique assembly of wild flowers, which can tolerate the cold windswept conditions and Serpentinite underlying minerals, toxic to many other species.
• The Viking ship & longhouse are reconstructions at Haroldswick, next to the turn-off for Unst Boat Haven. Free, always open.

• croft-house is the most northerly dwelling place in United Kingdom. (Buildings to the north, eg the radar station and Muckle Flugga lighthouse, are automated and unstaffed.) There is a small beach and a pleasant walk by the shore. Skaw was one of the last communities to speak Norn, though it persisted on remote Foula until the 20th century.
• Burrafirth is where the B9086 ends, becoming the narrow lane up to Hermaness. It has a good beach at the head of the inlet between Hermaness and Saxa Voe peninsulas.
• , on the north-western tip of Unst, is a nature reserve with thousands of seabirds nesting and wheeling over the spectacular cliffs and sea stacks. There are more than 10,000 pairs of gannets and 25,000 pairs of puffins, together with guillemots, shags and fulmars. You'll hear and smell them before you see them. Most of the birds arrive to nest in late April and are gone by autumn; the reserve is open all year.

is the small island which ceased to be the UK's most northerly habitation in 1995 when the lighthouse was automated. This is a Stevenson creation, first lit in 1858, after winter storms made short work of its 1854 predecessor.

, another half mile out, is finally, definitely the most northerly point of the United Kingdom. "Stack" implies a tall stand of rock, but it's a round crag, never inhabited, that's been dubbed "the full stop at the end of Britain." Legend says that Lady Jane Franklin came here in 1854 after the loss of her husband Sir John Franklin's "Erebus & Terror" expedition to find the North-West Passage. This legend casts her as a Victorian widow grieving in bombazine over the tumultuous northern ocean, but she was a tough explorer in her own right, entirely capable of clambering ashore up the steep rocks.

• Shetland Reel Distillery

• Wildlife spotting trips are available from various operators, mostly based in Lerwick to pick up trade from the cruise liners. The trips are all land based, since a minibus doesn't heave as much as a small boat whenever the wind gets up.

• Saxa Vord Resort

  phone: +44 1957 711711
  address: Haroldswick, Unst ZE2 9TJ
  Open April-Oct, may be available in winter. "The Sergeants' Mess" is more like a student residence than a hostel, with 26 single & double rooms sharing facilities, it's not a dorm / bunkhouse. "Shackleton Lodge" (sleeps 12) likewise has small individual rooms and is available for group bookings eg school trips. They also have self-catering, the 13 Nordabrake cottages (sleeping five), usually let by the week. Restaurant is open 18:00-21:00 plus Sunday carvery 12:00-15:00, café 10:00-16:00. The sergeants were attached to the RAF radar station, but don't head for the radar "golf ball", the resort is at the foot of the hill.
• Several self-catering cottages are also available.

You'll always have a mobile signal along the main road, but internet here can be very slow. Victoria's Vintage Tea Rooms in Haroldswick has free Wi-Fi for customers at a decent speed.

Natural hazards are the main risk, especially bad weather close to cliff edges. The bonxies (great skuas) will viciously dive-bomb anyone who approaches their nests.

The only way is back south by ferry to Yell, perhaps with a side-trip to Fetlar, then to Mainland Shetland.
