When Keeley Hawes was facing prison, violence and general corruption in BBC drama Line of Duty earlier this year, she tweeted a picture of herself in the sun-drenched ITV drama The Durrells as an antidote to all the grisly goings-on in her other role. It was a neat touch to show us a picture of the Corfu-set show, and just what we needed.

Corfu, the northernmost Greek island situated just off the western coast of Albania in the Ionian sea, is clearly a beautiful place. But why, I asked, had it fallen off my holiday map?

I had not been there since I was a 19-year-old inter-railer and ended up in a place called The Pink Palace, a ramshackle Corfiot hotel for backpackers. Drinking, wet t-shirt competitions and the kind of fun which did not pay too much heed to classical civilisation was the order of the day.

No, Corfu is not for me, I used to think. It's one of those Greek islands that has been spoiled by hedonistic travellers and swamped by concrete. In fact, I had only been back to Greece once since Pink Palace-gate, and that was to a family hotel in Cephalonia that did not live up to my expectations or the brochure.

But The Durrells made me think twice.

ITV’s drama is filmed on the island and is based on Gerald Durrell's memoir, My Family and Other Animals. In 1935, the Durrells — twenty-something novelist Lawrence, Leslie, teenager Margo and animal-loving Gerald (who grew up to be an eminent conservationist as well as an author) and their long-suffering mother who is played by Hawes — swapped England for Corfu.

They lived on the island until the Second World War broke out in 1939. And the picture painted by Gerald in My Family and other Animals, and in the more literary works of his elder brother Lawrence, of an unspoilt backwater with stunning scenery and wildlife was recreated beautifully in the TV series.

But of course the Durrells association with the island had a sting in its tail. The success of Gerald’s books put Corfu on the map, and he held himself responsible for the tourist invasion of the 1970s and 1980s, and railed against the island's overdevelopment.

So is there anything of his Greek paradise left? Those sun-drenched, sea-lapped scenes made me keen to look afresh at the place. Are there be pockets of this island that still have Hellenistic charm? 

The secret, it turns out, is to head to the north-east corner. This is real Durrell country and the part of the island brought most vividly to life in the books. And it is, for the most part, picturesque and unspoilt.

The Durrells moved around. They lived in the island's capital Corfu Town for a bit, which is in the middle. And I would recommend it. Much of the architecture is stunning, especially the graceful colonnades modelled on the Rue de Rivoli and built by the French during their brief occupation. It still hosts cricket matches in the central green, a quaint legacy of British rule.

But when you make the hour-long drive from there to the north-eastern part, you will discover pretty villages perched on rocky outcrops and postcard-worthy sandy beaches every mile or so. Getting to the beaches isn't always easy, but but it's always worth the effort. 

My tip would be to hire one of the diesel-powered speedboats for around £50 a day, plus £25 for diesel, and chug around the coast. All the hiring outlets call them "speedboats", but they don’t get much beyond 10 knots, and nor would you want to. They don’t require much skill or instruction, although I would recommend taking in the sun canopy when the winds pick up – steering can be tricky when it's gusty.

On your forays you can visit The White House in Kalami Beach (pictured from the sea), where Lawrence lived with his artist wife Nancy and wrote his ode to Corfu, Prospero’s Cell. You can eat in the taverna or rent rooms above, which haven't changed much since he resided here.

Nearby Agni (about ten minutes “speeding”) is a must-see. It's a little town with three tavernas, the oldest dates back to 1879 and the Taverna Agni is probably the best restaurant on the island.

You can also indulge in some celebrity-spotting. The gin palaces of the super-rich dot the sea. This is where George Osborne and Peter Mandelson had a confrontation that made headlines in 2008 while on board the yacht of Russian oligarch Oleg Deripraska.

One of the island’s prettiest spots for dropping anchor and having a swim is the tiny bay that hosts a little stone shrine to St Arsenios, just south of Agni Bay. This is where Margo sunbathes in the first episode of The Durrells, much to the surprise of the young priest tending the shrine. In My Family and Other Animals, it’s where Lawrence, Nancy and their bohemian friends swam naked.

If you search, you’ll find a sea-level cave accessed by a corridor in the rock, with a separate underwater exit. It's gorgeous.

Probably the prettiest of the villages is Agios Stefanos – not to be confused with a (very different, much more touristy) town of the same name on the north-west coast. The one on the north-east coast is a stunning little place with a bay, an array of restaurants, two well stocked (if expensive) supermarkets and a number of beautiful houses clinging to the hillsides above. I stayed in Villa Sotiris (pictured), just outside the town, which is run by villa hire company Simpson Travel. 

The nightlife was quiet, which is just how I like it. There is a small marina for boats and a large beach in the village, with rocks at the end of a peninsula, which are excellent for snorkelling. It also provided an excellent base from which to explore the island's rugged interior and the flora and fauna that so dazzled the Durrells.

Cat lovers should also head to Corfu, even if you will bemuse some of the locals. They seem to be everywhere and Corfiots generally find them a pain. But our house had three furry friends who were more than keen on a slice of octopus stifado when it was offered, which was pretty much always. The Durrells would doubtless have done the same.
