Santorini (Greece)

1 Santorini (Greece)

The fabulous island of Santorini is the southernmost of the Cyclades, lapped by the beautiful waters of the Aegean. Its volcanic origin makes it a harsh and rugged land, characterized by dark cliffs from which emerge spectacular white-walled villages whose churches stand out with their blue domes. So whether you are passionate about photography or just want a sun and sea holiday, Santorini is the perfect destination.

The best season to visit Santorini is between April and November. Come here if you are looking for a romantic destination where you can spend unforgettable moments with your loved one. The island’s sunsets are proverbial, as is the scent of a glass of wine sipped on one of the many terraces overlooking the sea.

What is there to see in Santorini? History buffs come here to learn more about Greece’s cultural heritage. The excavations of Akrotiri are considered one of the most important prehistoric finds ever and go back to 3600 BC. The city has survived in a similar way to Pompeii, having been submerged by lava from a volcanic eruption.

Crete (Greece)

2 Crete (Greece)

Of all the Greek islands, Crete is the largest and the fifth largest in the Mediterranean Sea. Once the center of Minoan civilization, today it is the most popular island for tourists looking for sun, sea, and nightlife in one exclusive place. Beautiful mountains, crystal clear water, and sunshine almost all year round. Being so large, Crete offers its tourists a wide choice: you can sit on one of the many equipped beaches, rent an umbrella and sun lounger, or, wearing comfortable shoes, go to secluded bays, where you will feel like the lord of the universe.

History buffs will find Crete the perfect holiday destination: explore the Heraklion Museum and the perfectly preserved Venetian mountains in the village of Chania, or visit the Castle of Rethymno, located in close proximity to a beautiful sandy beach.

Visit Crete between April and mid-October: the climate is perfect for a swim or a comfortable nod on one of  Crete’s many beaches along the coast.


3 Mauritius

Mauritius is a paradise from the warm waters of the Indian Ocean; it is over 500 kilometers from Madagascar. The Archipelago includes the mother island of Mauritius and the sister islands of Agalega, Cargados, Carajos, and Rodrigues.

Unlike most of the destinations listed here, you can travel to Mauritius all year round. Its favorable location, just below the Tropic of Cancer, makes it a land of the sun where temperatures never drop below 16°C, even in winter.

As if that weren’t enough, the islands of Mauritius boast fabulous beaches. Who doesn’t love the feeling of soft sand underfoot on a hot sunny day while the waves of the sea beckon you for another dive that afternoon? So, come and relax under the umbrella or brace yourself for the thrill of scuba diving. The surrounding seabed will take your breath away thanks to the presence of coral formations that are home to hundreds of species of fish and crustaceans.

Mauritius is a crossroads of cultures where diverse ethnic groups and religions live together in exemplary harmony. The majority of the population is Hindu, with a strong Creole influence. In the cities, you can breathe a simply irresistible cosmopolitan atmosphere: this trip will open your mind and soul!

Hvar (Croatia)

Hvar (Croatia)

You have landed on Hvar. This beautiful island of Croatia is considered one of the top beach destinations in the state by many specialized publications. In its cities, you can still breathe the passage of ancient civilizations such as the Greeks, Romans, and Venetians. History buffs shouldn’t miss a trip to Spanjola Fortress, built by the Venetians in the 13th century. It was also of prime importance in later centuries, especially in 1571 when the Turks invaded the island.

Not to mention the coast! Magnificent rocky or sandy beaches gently descend into the crystal clear waters of an irresistible sea. If you want to reach postcard places, take a trip to the Pakleni Islands, which are not far from here, and enjoy the silence and privacy on the pristine sand.

Also known as the island of lavender, the island of Hvar is dotted with fields of this fragrant plant, souvenirs par excellence to take home in the form of scented sachets, essential oils, or soaps.

Rarotonga (Cook Islands)

5 Rarotonga (Cook Islands)

Of all the Cook Islands, a New Zealand paradise nestled in the heart of the Pacific Ocean, Rarotonga is surely the crown jewel. This paradise is not only a popular travel destination for New Zealanders but has also slowly been discovered by mass tourism in recent years.

Rarotonga will also be a small island, no more than 20 miles in circumference, but it will give you the impression of a unique, immense vacation spot. The bus service works very well and allows you to reach all kinds of beaches, lagoons, shops, churches and everything you need to immerse yourself in the nature and culture of the place. In the villages, you can still breathe the Polynesian atmosphere of the first Cook settlers who came from Tahiti about 1400 years ago. In more modern areas, however, Maori culture reigns supreme, so don’t be surprised at the smiles of the locals, who may decide to invite you into their home for dinner to show you the beauty of the local culture.

Rent a parasol on one of the picture-postcard sandy beaches or indulge in snorkeling and diving in a fantastic sea in the company of tropical fish species and giant sea turtles.

Sri Lanka

6 Sri Lanka

You have arrived in Sri Lanka, also known as Ceylon, an island nation in Asia that emerges from the waters of the Indian Ocean. What will impress you about this fabulous country is its fabulous beaches and irresistible cuisine.

In addition, there are 26 natural parks and 2 marine parks to visit, the most famous being Yala National Park which is home to the world’s largest population of leopards.

Unlike many other islands mentioned here, Sri Lanka offers a tropical and warm climate whenever you decide to visit. The area is affected by two monsoon seasons that affect different parts of the island at different times of the year.

And suppose the beaches have not already seduced you. In that case, all you have to do is sit down at the table and get ready for the delicious experience of a lifetime: the cuisine maintains a unique identity, a mix of flavors and spices that will make you fall in love.

Koh Phi Phi (Thailand)

Koh Samui (Thailand)

You have never seen an island like Koh Samui in Thailand. The most iconic scenery of this fabulous place is surely the round stones of Hin Ta and Hin Yai, large stones that rest on the shore where bathing is a real pleasure.

Come and admire, for example, the gigantic golden statue of the Buddha, which is more than 12 meters high and stands on a terrace that offers a breathtaking view of the rest of the island. Do you like oddities? Don’t miss the Mummy of the Monk of Wat Khunaram, the remains of a monk who died silently while meditating and is now on display in a shrine.

If you prefer hiking in nature, consider taking a trip to Namuang Falls instead, whose natural beauty will leave you speechless? Then, have a picnic among the rocks and seduce yourself to Thailand’s untouched nature.
