The Isles of Scilly or the Caribbean?

Leave from Penzance by boat or take the Skybus from Exeter, Newquay or Land's End and your journey time to the white sand beaches of The Isles of Scilly archipelago could be just 15 minutes.

'Although we're only 28 miles off the coast of Cornwall, the islands feel like nowhere else in England,' says David Jackson (@IOSPartnership), executive director of the Isles of Scilly's not-for-profit tourism agency, Islands' Partnership.

For a weekend break, the main island of St Mary's is best, with the wonderful Star Castle hotel offering rooms in a 16th-century castle and lobster caught by the hotel's own fishing boat.

Both images contain a rocky coastline and a blue sea

The Cornish coast or the Mediterranean coastline?

The last (or first) county in England is an atmospheric terrain of moor and beach. Hunt out filming locations from the BBC's Poldark and don't miss glorious Porthcurno Beach.

'The colours are practically tropical with turquoise sea and white sand,' says local Sarah Ferrie (@sarahlferrie). 'You'll often get lucky and see dolphins or basking sharks and the cliffs are spectacular.

'The beach holds a secret too – it's where the communication cables leave the UK to connect to the rest of the world. There's a little museum up from the car park.'

Both images have colourful buildings surrounded by a range of trees

North Wales or rural Italy?

Fans of 1960s cult TV series The Prisoner will recognise Portmeirion's jumble of domes and turrets built by the visionary architect Sir Clough Williams-Ellis, but this Italianate town near the Welsh coast is far from a TV set.

Book a room at the super swish Hotel Portmeirion or one of the huddle of historic cottages; have a coffee in Battery Square and stroll through the Gwyllt woodland – we reckon you'll agree with Robin Llywelyn (@Portmeirion), Sir Clough’s grandson that, 'Portmeirion really is a place like no other.'

Answer: B is in the UK

Both images have mountains in the background, rocks in the foreground and surrounded by the sea

The Isle of Skye or New Zealand?

Dramatic peaks plunging down to craggy sea lochs; high cliffs cut into sea stacks and caves – there's more than 400 miles of coastline on Skye, as well as the peerless Cuillin mountains, rearing up to tempt walkers seeking to follow in Michael Fassbender's footsteps (2015's Macbeth was partly shot here).

'It's a landscape that is hugely diverse,' says Mitchell Partridge (@skyeghillie), who takes visitors out on wild walks of raw beauty in the rugged north. 'A gentler, lusher landscape in the south, and viewing the Cuillin Mountains from Elgol you could be in New Zealand.'

Answer: B is in the UK

Both images contain a scuba diver in the sea. The sea in one is much clearer than the other

Scapa Flow or the Red Sea?

Want to go diving on your weekend break?

'You don't need to go overseas for one of the world's top wreck diving destinations,' reveals Sara Turner of Scapa Scuba (@ScapaScuba). 'Head north to Orkney instead – there are regular flights to Kirkwall and ferries from Aberdeen – and you'll find the vast sheltered waters of Scapa Flow.

'It's a diving mecca for those who love to dive wrecks. Home to the German High Seas Fleet that was scuttled here on 21 June 1919, Scapa Flow is undoubtedly one of the best dive sites in the world.'

Even though you're staying in the UK, don't forget to check that you have the right level of cover for adventure activities if you do plan on a visit to the depths.

Both images contain a large lake with mountains either side

Loch Etive or the Norwegian fjords?

Scotland's lochs should be as famous worldwide as the Norwegian fjords; their waters – depending on the time of year – reflecting snowcapped mountains and scudding clouds, heather-cloaked moorlands and bright blue skies.

Loch Etive is one of the best: a sea loch where the Atlantic meets the crisp mountain waters.

'Who needs the Norwegian fjords when Scotland boasts this sweeping sea loch, complete with vaulting mountains, shimmering Atlantic waters and brooding castles?' Robin McKelvie (@robinmckelvie), Scottish travel writer and Scotland specialist, points out. 'Add in the deeply unusual Falls of Lora, a horizontal waterfall, and Loch Etive has it all.'

Answer: B is in the UK

Both images have some rusted boats that have been beached on the sand

Dungeness Beach or the Aral Sea

Some say desolate, we say beautiful – Dungeness is like nowhere else in the UK. Its shingle headland juts out into the English Channel, sheltering Romney Marsh.

'With the old, rusting flotsam and jetsam from ancient ships, and the stark modernist shape of the Nuclear Power station, this 468 acre national nature reserve is a fabulous place to visit in all seasons,' says Sophie Whelpton of Mulberry Cottages (@MulberryCotts). It's also a bird sanctuary, so bring the binoculars!

The best place to stay during your weekend break is Dungeness Retreat, a wooden- and glass-walled contemporary cottage that sleeps up to 10 people.

Answer: A is in the UK

Could you tell which was the exotic destination and which was the UK holiday spot? We thought not! If the similarity hasn't persuaded you to try somewhere in the UK this season, maybe the fact that many of these weekend break destinations have found fame on TV and in film will.
