Travel in Guernsey: an island whose ways in belong to its government

Why the States own Guernsey's airport and harbours

Guernsey has one airport, at La Villaize in the parish of Forest, and St Peter Port Harbour is its main port. Both belong to the States of Guernsey, the island's parliament and government, which also owns the second main harbour and runs the water and wastewater services on the same footing. Electricity and the post were turned into companies, and the States still hold every share in both.

The States also decided to buy Aurigny, whose name is the French form of Alderney, to protect the island's air links, and the sale was completed on 15 May 2003. The airport offers flights to the United Kingdom, to Alderney and Jersey and to international destinations, and a visitor who flies in on Aurigny arrives on a publicly owned aircraft at a publicly owned runway.

Guernsey Airport reports total passengers by route every month, covering the United Kingdom, international routes and flights inside the Bailiwick, and Guernsey Harbour reports its own passengers to the United Kingdom, France and the other islands. The States of Guernsey's Data and Analysis Service adds an exit survey of departing passengers at both, and has published quarterly and annual traveller bulletins from that material since 2023. The survey needs contact with people in transit. In 2020, when the pandemic restricted contact with people in transit through the airport and harbours, the States did not run it, and no official count of visitors exists for that year. The passenger returns for that year show how empty the routes became: about 105,000 people moved through the airport and harbours in April 2019, and about 1,000 in April 2020.

How Guernsey's travellers divide between air and sea

Counting residents and visitors together, and private boats and aircraft as well as scheduled services, 533,253 people travelled to and from Guernsey in 2025. That was 3% more than the 519,028 of 2024 and 5% fewer than the 563,879 of 2023. The States counted 282,028 of the 2025 travellers as visitors; the rest were islanders going away and coming home.

Air carried more than twice as many people as the ferries in 2025, and it carries most of the islanders. In the second quarter of 2026 the States counted 59,527 residents leaving the island, 40,803 of them by air and 18,724 by ferry, and 73% of them were travelling to the United Kingdom. The same routes that bring visitors in take the island's own population out, and a drop in resident travel shows in the totals: departing residents fell by 15% between the second quarters of 2025 and 2026, which pulled all departures down by 3% to 156,415 even while visitor numbers rose.

In 2025, 26% of visiting parties spent between £1,000 and £1,499 on travel and accommodation and a further 26% spent more than £1,500. Only 4% of parties spent less than £250, and the share spending more than £1,500 had been 32% in 2023 and 41% in 2024.

What changed on the sea routes to Guernsey

The sea was the first way in for visitors. The first tourist guide to Guernsey was published in 1834, and in the 19th century the London and South Western Railway and the Great Western Railway ran competing boats from England to St Peter Port, racing each other for the one convenient berth. The race ended with the sinking of the SS Stella in 1899. Britannica lists the island's shipping links as running to Jersey, Alderney and Sark, to Weymouth in England and to Saint-Malo in France.

Ferry traffic grew in 2025 while the cruise trade shrank. Brittany Ferries published its own figures for a rise in passengers that year, and the States counted 28,029 visitors from France in 2025, 88% more than in 2023. In the second quarter of 2026 ferry passengers were broadly level with a year earlier and 14% above the same quarter of 2023.

How the cruise trade contracted

Cruise ships anchor in the roadstead outside St Peter Port Harbour, and the States' own series shows how much that trade has moved. About 115,000 cruise passengers were counted in 2013 and about 117,000 in 2019. In 2025 the figure was 28,397. Sixty-one cruise ships were due at Guernsey in 2025, with four more each for Herm and Sark and seven for Alderney, and 51 were scheduled for Guernsey in 2026. Cruise visitors in the second quarter of 2026 were 40% fewer than a year earlier and 78% fewer than in the second quarter of 2023.

What the tides mean for yachts

Visiting yachts are the other sea arrival, and they have grown: 19,974 people came in by private boat in 2025, and yacht visitors in the second quarter of 2026 were 46% above the same quarter of 2023. The waters they cross have a tidal range of 10 metres and currents of up to 12 knots among many islets, rocks and reefs, and the combination makes sailing around the Bailiwick dangerous.

Which rules apply at Guernsey's border

Guernsey is a Crown Dependency. The Bailiwick is a separate jurisdiction and forms no part of the United Kingdom, but for immigration and nationality it is United Kingdom law that applies, through the Immigration Act 1971 extended to the island by Order in Council, and Guernsey may not set different immigration controls. The whole jurisdiction lies inside the Common Travel Area of the British Islands and the Republic of Ireland.

Brexit changed the terms for continental travellers, although the island was never a member of the European Union. From 1 January 2021 all nationals of the European Union other than British or Irish ones have needed a visa before travel to the United Kingdom, the Bailiwick of Guernsey, Jersey or the Isle of Man for anything other than a visit. Anybody coming to work needs a visa and a Population Management document as well. Free travel to the continent ceased from 2021, and international driving licences became one of the added procedures.

A longer stay meets the island's housing rules. Guernsey splits its housing into local market properties, which only qualifying residents may occupy, and a set number of open market properties that anyone may live in, and the open market ones cost much more to buy and to rent. The rules govern occupation and apply equally to owners and tenants. In 2025 the States counted 1,118 visitors who stayed more than 31 nights, under 1% of the total.

The practical record is British with local variations. The currency is the pound sterling, the calling code is +44, sockets take British BS 1363 plugs and Europlugs at 230 volts, and traffic keeps to the left. Clocks follow Greenwich time in winter and move an hour forward in summer.

When Guernsey fills and when it empties

In 2019, the last full year before the pandemic, about 55,000 people passed through in January and about 183,000 in August, more than three times as many. July carried about 168,000 and October about 100,000.

The island had between 1,887 and 1,891 units of visitor accommodation open for booking each month from April to June 2026, and occupancy rose from 65% in April to 73% in May and 84% in June. The occupancy level for 2025 as a whole was 61%.

At Guernsey Airport the Met Office's averages for 1991 to 2020 give 251 hours of sunshine in July and 51 in December, a July maximum of about 18.9°C against 7.8°C in February, and 37 mm of rain in July against 105 mm in December. Winter is also the windy half of the year, with a mean wind speed of about 15 knots in December and 10 in August. Over a year the station records about 1,808 hours of sunshine, against about 1,403 for the United Kingdom as a whole over the same period.

Visitors who stayed at least one night and under 31 nights in 2025 stayed for an average of 4.6 nights, down from 4.9 in 2024, which added up to 866,278 bed nights. A further 43,016 came for the day by air or ferry, 31% more than in 2024. In the second quarter of 2026 the average stay was 4.4 nights, and 64% of staying visitors that quarter slept in hotels and 20% with friends or family.

How visitors move around Guernsey's lanes

Britannica gives the island an area of 62 square kilometres, and its road network runs to 260 miles. The motor vehicle is the main way around. Beside the main roads runs a network of country lanes, some of them branded Ruette Tranquille, French for quiet street, where pedestrians, cyclists and horse riders have priority and the recommended speed is 15 mph. Campaigners have lobbied for that limit to become legally binding.

Buses are run by Stagecoach South West under the name Buses.gg, on behalf of the States' Committee for Environment and Infrastructure. In 2025, the operator's first year on the island, passengers made 1.7 million bus journeys. Coach tours reach a smaller share of visitors: 11% of them took one in 2025, a figure that includes Le Petit Train as well as the bus companies. The WWII Occupation Trail, whose boards are read through the VisitGuernsey app, is laid out as walking, cycling and driving routes.

Guernsey Post's pillar boxes have been painted blue since 1969 and the telephone boxes since 2002, and a pillar box of 1853 is still in use in Union Street, St Peter Port. Most visitors eat out: 85% did so in 2025, and 59% did some shopping.

How the smaller islands are reached through Guernsey

Of all visitors in 2025, 33% went island hopping, against 38% in 2024 and 34% in 2023, and 31% of leisure visitors named the nearness of Herm, Sark, Alderney and Jersey as a reason for coming.

Sark lies 7 miles (11 km) east of Guernsey. It measures 3 miles long and 1.5 miles wide, in two parts, Great Sark and Little Sark, joined by a narrow isthmus called La Coupée. It can be reached only by boat, because aircraft are banned, and automobiles are prohibited on its roads, with farm tractors the one exception. People get about by horse-drawn carriage and by bicycle. Accommodation on Sark is limited, and according to Britannica most visitors arrive on a day trip from Guernsey or from a cruise ship.

Herm belongs to the Guernsey jurisdiction and sits inside one of Guernsey's ten parishes, and its visitor accommodation includes self-catering cottages and apartments. Alderney is reached by air from Guernsey Airport and by sea. Its main inlet, Braye Harbour, is protected by a breakwater of 1,000 yards (914 metres), and most of the island is a tableland above 60 metres.

Jersey is the other bailiwick of the Channel Islands. In 2025, 19,270 visitors to Guernsey gave Jersey as their home, 7% of the total, and in the second quarter of 2026 their number was 31% up on a year earlier.

What visitors come to Guernsey to see

In the 2025 survey, 85% of leisure visitors named the island's natural beauty and its beaches as the draw and 56% named its history and heritage. Half of all visitors, 52%, went to a museum, a gallery or a monument that year.

Castle Cornet, where Royalist troops held out until its surrender in December 1651, Fort Grey and the Guernsey loophole towers belong to the island's earlier military history. The larger layer is German. The occupation ran from 30 June 1940 to 9 May 1945, and the harbour was where it began: on 28 June 1940 a German bombing raid on St Peter Port hit tomato lorries lined up on the quay, which the attackers had mistaken for military vehicles, and killed 33 civilians.

The concrete that followed is now visited as museums. The German Underground Hospital, the German Naval Signals Headquarters, which handled all radio traffic to and from Germany and the other islands, the La Valette Underground Military Museum and a Type 380 bunker at Douglas Quay that housed a 7.5 cm anti-tank gun are all open to visitors. The German Occupation Museum stands within walking distance of the airport.

Victor Hugo arrived on Halloween 1855 and lived in St Peter Port until 1870. His house there, Hauteville House, is a museum administered by the city of Paris, and the French consulate in Guernsey is based in it.

Liberation Day on 9 May is a public holiday across the Channel Islands. It falls as the season builds: the passenger count of 2019 climbed from about 105,000 in April to about 131,000 in May.
