Alderney day trip from Guernsey: flight vs ferry, full itinerary

Alderney from Guernsey: the basics

Alderney is the most northerly of the British Channel Islands — a Crown Dependency group in the English Channel, entirely distinct from the Channel Islands National Park in California. It sits approximately 50 km northeast of Guernsey, near the French coast at Cap de la Hague.

Of the three small day-trip destinations accessible from Guernsey (the others being Herm and Sark), Alderney is the furthest, the most logistically complex to reach, and the one that rewards the most once you are there. It is a genuine island with its own identity: 2,000 residents, a proper capital, a railway, serious wildlife, and a layer of WWII history that makes it historically one of the most significant sites in the British Isles.

This guide covers the two transport options (plane and ferry), explains the tradeoffs, and outlines how to structure a day.

Option 1: the Aurigny flight (recommended year-round)

Why fly

The Aurigny Air Services flight between Guernsey Airport and Alderney Airport is the most reliable, most frequent, and most weather-resistant way to reach Alderney. It operates year-round on multiple daily schedules, takes approximately 25 minutes, and uses Britten-Norman Islander or Dornier 228 aircraft — small turboprops that feel more like a taxi than an airliner, but are entirely safe and operated to full CAA standards.

Flying gives you the earliest possible departure from Guernsey (first flights are typically before 09:00) and the latest possible return (last flights often after 18:00), maximising time on the island. It also means your plans are not affected by sea conditions.

Booking

Aurigny tickets are available on the Aurigny website. Book in advance, especially during the summer season and the Alderney Bird Festival in October when demand is high. Fares vary but expect to pay approximately £50-90 return per adult as a reasonable baseline in 2026, depending on how far in advance you book.

Guernsey Airport logistics

Guernsey Airport is approximately 5 km south of St Peter Port. It is reached by bus (Route 71 and several others serve the airport from St Peter Port) or by taxi (approximately 15 minutes, £15-20 in 2026). Check in at Guernsey Airport at least 30 minutes before departure — the airport is small but queues can build during busy periods.

Alderney Airport

Alderney Airport is a 10-minute walk or short taxi ride from Braye Beach and 15-20 minutes from St Anne town. There is no regular bus at the airport, but taxis are usually waiting for flights. The airport terminal is very small — a single check-in desk and waiting area — and departures are relaxed compared to mainland UK airports.

No UK or Channel Islands visa complications arise for travel between the islands. The British Channel Islands operate within the Common Travel Area, and inter-island flights do not require passport presentation for British citizens, though ID may be requested.

Option 2: the summer ferry

Seasonal operation

A passenger ferry connecting Guernsey to Alderney operates in summer only, typically from approximately May to September. The service is not operated by Condor Ferries (which serves Jersey and Guernsey from the UK and France) but by a smaller local operator — check the Alderney Shipping Company or Manche Iles Express schedules for the current season’s timetable.

The sea crossing takes approximately 2-3 hours, significantly longer than the Aurigny flight. The route passes through or near the Alderney Race, one of the strongest tidal currents in the world, which means the crossing can be rough even in moderate weather and is cancelled more frequently than the Aurigny flight.

When the ferry makes sense

• If you prefer sea travel and are not in a hurry
• If you want to bring bikes or larger equipment (check carrier policy)
• If you are travelling as part of a multi-island island-hopping route (some ferry schedules connect Alderney back to Jersey as well as Guernsey)
• If Aurigny flights are fully booked and the ferry has availability

When to choose the flight instead

• Year-round reliability is important
• You have children or companions with sea-sickness concerns
• You want the maximum possible time on the island
• You are visiting outside the summer season (ferry does not operate)

A full day itinerary for Alderney

This assumes the first Aurigny flight from Guernsey (approximately 08:30-09:00) and a return on a late afternoon or evening flight (approximately 17:00-18:30). Adjust for actual flight times when you book.

Morning: arrival, Braye Beach, and St Anne

08:30 — Depart Guernsey Airport on Aurigny.

08:55 — Arrive Alderney Airport. Take taxi or walk to Braye Beach (10 minutes by foot, 5 minutes by taxi).

09:00-09:45 — Braye Beach. The island’s main beach is quiet in the early morning. Walk the breakwater for views of the Alderney Race current (visible as a line of disturbed water north of the breakwater head when the tide is running). Take in the harbour and the approach.

09:45-11:00 — Walk uphill from Braye to St Anne town (approximately 15 minutes). Explore Victoria Street and the main square. Visit the Island Museum (School Lane, small charge, excellent for orientation). The market runs on some mornings — check locally.

Midmorning: Mannez Lighthouse and the northeast coast

11:00-11:20 — Walk, cycle, or take a taxi from St Anne to Mannez Quarry (approximately 2.5 km from St Anne, 20-25 minutes on foot or 5 minutes by taxi).

11:20-12:30 — Visit Mannez Lighthouse. Walk the northeast headland (Quesnard) for views and seabirds. The area around the lighthouse is excellent for coastal wildflowers in spring. This is also the starting point for one of the island’s best coastal walks north.

Note: if the Alderney Railway is operating (typically summer weekends), consider taking the train from Braye to Mannez and returning by taxi or on foot.

Lunch: return to Braye or St Anne

12:30-13:30 — Return to Braye Beach for lunch. The Braye Beach Hotel terrace is the best outdoor lunch option on the island — well-prepared food with harbour views. Alternatively, several pubs and cafés in St Anne serve lunch (the Georgian House, the Campania, and the First and Last are all well-regarded).

Afternoon: fort, memorial, or wildlife

13:30-15:30 — Choose your afternoon focus:

Option A — Fort Clonque and the west coast: Taxi or walk west from St Anne to Fort Clonque on the west coast (approximately 30-40 minutes on foot). Walk the causeway at low tide, explore the exterior, and return via the west coast path with views of Les Etacs gannet colony (visible from the coastal path).

Option B — Hammond Memorial and WWII circuit: Take a guided or self-guided tour of the main WWII sites: Hammond Memorial, Fort Albert, and surviving fortifications. See our Alderney WWII fortifications guide for a detailed route.

Option C — Burhou puffin boat tour: If operating in the right season (May-July), a boat tour to Burhou Island for the puffin colony is one of the best wildlife experiences in the British Channel Islands. See our Alderney puffin watching guide for booking and timing.

15:30-16:00 — Return to St Anne or Braye for a final drink or purchase from the island shops.

16:30-17:00 — Head to Alderney Airport for return flight.

17:00-17:30 — Depart Alderney. Arrive Guernsey approximately 17:25-17:55.

Eating and drinking on Alderney

Alderney has a good range of pubs and restaurants for an island of its size. Prices are broadly comparable to Guernsey — slightly higher than UK mainland equivalents, reflecting the logistics of supply.

Braye Beach Hotel: Terrace bar and restaurant with harbour views. Best outdoor lunch spot on the island in good weather. Reservations advisable in peak summer.

The Georgian House Hotel restaurant: In St Anne, one of the island’s better restaurants for a proper sit-down meal. Well-regarded for fish and local produce.

The First and Last: A pub in St Anne with a name that reflects its position on the island. Traditional pub food, good cider selection.

The Campania: St Anne restaurant with a more European-influenced menu. Popular with residents and visitors alike.

Victoria Street cafés: Several small cafés and bakeries on Victoria Street in St Anne serve coffee and light lunches.

A day trip in summer gives you time for breakfast in Guernsey, a mid-morning snack in St Anne, and lunch at Braye or in town before the afternoon activities. There is no fast food on Alderney — all eating involves a sit-down or a deli counter. Budget accordingly.

Weather and seasonal considerations

Alderney is the most northerly of the British Channel Islands and is therefore marginally cooler than Jersey or Guernsey. It is also more exposed — the island sits directly in the path of Atlantic weather systems moving from the southwest, and gales are more frequent than further south.

For day trips, weather matters primarily for the Aurigny flight (fog and crosswinds can delay or cancel flights) and for outdoor activities. Flights are cancelled less often than ferries but the small aircraft used by Aurigny are more susceptible to crosswinds at the island’s short runway than larger aircraft.

The best months for a day trip are May, June, July, and August. September and October are also excellent — cooler and occasionally windier, but October coincides with the Alderney Bird Festival, which transforms the island.

Budget

For a day trip from Guernsey to Alderney:

• Aurigny return flight: approximately £50-90 per adult (book in advance for best prices)
• Taxi from airport to Braye/St Anne: approximately £5-10 one way
• Lunch: £15-25 per person at a pub or café
• Alderney Railway (if operating): small charge, typically £5-8 return
• Island Museum: small entrance fee (£3-5 estimated)
• Optional boat tour to Burhou: typically £20-30 per person

Total day-trip budget (flight + transport + lunch + one attraction): approximately £100-150 per adult in 2026. An Alderney day trip costs more than a Herm day trip primarily because of the Aurigny flight cost, but the experience is substantially different.

Frequently asked questions — Alderney day trip from Guernsey

How long is the Aurigny flight from Guernsey to Alderney?

Approximately 25 minutes. It is a short hop on a small turboprop aircraft, more like a flying taxi than a conventional commercial flight.

Do I need a passport to fly from Guernsey to Alderney?

For British citizens, ID is not formally required for inter-island travel within the British Channel Islands (both are Crown Dependencies in the Common Travel Area). However, Aurigny may request identification, and carrying a passport or driving licence is advisable. EU citizens and other non-British nationals should carry a valid passport.

Can I get to Alderney without flying?

Yes, by ferry in summer only. The crossing takes 2-3 hours and is operated by a local carrier (check current operators for the season you are travelling). The ferry route is subject to cancellation in rough conditions — the Alderney Race current makes the approaches challenging. The flight is more reliable for a day trip.

Is there public transport on Alderney?

A small bus service operates in the main season. Taxis are the most flexible option. Cycling is excellent — bike hire is available in St Anne. The island is small enough that most visitors walk between key sites.

Is the Alderney Bird Festival worth travelling for?

Yes, strongly. See our Alderney Bird Festival guide for full detail. The October event is the most significant wildlife festival in the British Channel Islands and attracts birdwatchers from across Europe.
