The stunning Samaria Gorge cuts a deep path between the White Mountains and the shores of the Libyan sea. The gorge takes its name from the church of Ossia Maria, which was located in Samaria village, which once laid in the centre of the gorge and was finally vacated in 1962 to make way for the national park.

This is the longest gorge in Europe and extends for a distance of 16 km and has become a popular destination for naturalists and hikers from all corners of the planet. The park is home to a diverse range of flora and fauna, including some rare species of wildflowers and butterflies. The trek through the gorge is a bit challenging, but well worth the effort for the spectacular scenery that awaits the visitor.

Waterfalls of Samothraki

Greece is famous for its beaches and so is Samothraki, but there is one unique natural wonder on this island called vathres. Vathres are natural rock pools of water created by the waters of the innumerable waterfalls which rise from the Saos Mountain on their way back to the ocean.

There are hundreds of vathres on the Samothraki island but the most famous are those found near Therma, at the confluence of the Tsivdogiannis and Fonias rivers. A waterfall hike to this beautiful place is a must do activity in Samothraki as a swim in the clear waters of this vathres is an exhilarating experience.

Most of the waterfall trails begin at the town of Therma, so it is a good idea to make base there to explore the many waterfalls surrounding the place. The most beautiful waterfall is named Kleidosi and is situated on the Fonias river and cascades down from a height of 35 m.

Volcano of Nisyros

The Nisyros volcano on the island of Nisyros is a very much active volcano and one of the youngest in the whole of Greece. Legend says that the volcano was created by a stone thrown by the Greek god, Poseidon. It is located just south of the popular beach Island of Kos and is one of top to do activity if you are there.

An hour-long scenic trip from Kos will bring you to this geological gem. Be sure to climb up to the craters of Stefanos and visit Nikia and Mandraki while you are there. After you have docked at the harbor, head to the ancient village of Nikia, which lies on the edge of the Stefanos crater and pick a spot at the edge from where you will feel the heat emitting from the crater.

It is important to note that the crater walls are quite steep, so young children and those with any health problems should not venture far to the bottom. After exiting the volcano with the smell of hydrogen sulphide still in the air, spend the rest of the day in Mandraki and stroll down the cobbled streets and marvel at the picturesque white Nisyrian houses. Head to the Monastery of Panagia Spiliani, the highest point on the island to enjoy a panoramic view of Mandraki.

Zakynthos is one of the largest Greek islands and the second most visited after Corfu. As with other Ionian islands, Zakynthos too is full of green pastures and fertile valleys that offer spectacular views of the countryside. However, it is the west coast of Zakynthos where one of the most beautiful natural sites is located, the stunning Blue Caves.

The caves are only accessible by boat, but this has not deterred visitors in any way as they have become one of the top natural attractions of Greece, especially at some given time in the day. There are plenty of boat trips on offer to get to the caves, of which Kianoun is the biggest. Here you can witness the wonderful phenomenon of light reflecting the vibrant blue colors of the water, especially during sunrise and sunset.

Within the blue caves are arches created by water erosion over thousands of years and once inside the caves one gets the feeling of being surrounded within a surreal environment. For those who like diving, the blue caves, getting under the water and admiring the beauty of the cave rocks is an unforgettable adventure.
