The Vouraikos Gorge

Why visit the Vouraikos Gorge?

The spectacular scenery

The abundance of wildlflowers – including a few found only in Greece, and one found only in the Gorge itself.

A variety of birds, mammals, reptiles, amphibians, butterflies, and other insects.

The heritage railway and the Mega Spilio Monastery

There are two ways to see the Vouraikos Gorge – either you walk through it, or take the train. Or perhaps you take the train, and spend a couple of hours wandering around near each station until the next train comes. The latter is probably best done at weekends when there are five trains each way a day, rather than the three on weekdays.

Beginning near the village of Priolithos in the Aroania/Chelmos mountains, the Vouraikos river flows some 40km past the towns of Kalavryta and Diakopto to the Gulf of Corinth. The gorge itself is the last half of this journey, where the river has cut through limestone and conglomerates, and now passes through dense vegetation and tunnels with many caves, passes and crags.

Legend has it that the name derives from Boura, a mythological daughter of Ion and Helice. She was courted by Hercules who opened the gorge in order to get closer to her.

The river and gorge and part of the National Park of Chelmos-Vouraikos, which was established in 2009 to preserve the biodiversity, the natural resources, and the ecological value of the natural ecosystems in the area. The steep sides of the gorge provide a myriad of micro-climates, with plenty of opportunity for plants to evolve into endemic species, and for scarce animals to find refuge.

The endemic plants include Silene conglomeratica (endemic to the gorge), Aurinia moreana, and Campanula topaliana subsp. cordifolia (pictured left).

Otters Lutra lutra hunt along the river. Bats (Miniopterus sehreibasi, Myotis blythii, Myotis myotis, Rhinolophus blasii, Rhinolophus ferrumequinum) also live in the caves and the rock crevices.

Several birds of prey nest on the rock ledges higher up.

The railway line dates from the 1890s. Charilaos Trikinos was the Greek prime minister at the time, and he wanted to create local railway networks to connect the interior regions with the main railway. These local railways were to be narrow gauge, because small trains were better suited to the mountainous country and were cheaper to construct. It also meant that, using a cog system, the trains could negotiate steeper inclines. This railway climbs 750m in its 20km journey. Since it was inaugurated on 10th March 1896, the trains have run every day, regardless of the weather (although parts of the line were closed for refurbishment when I visited).

The E4 European long distance footpath starts in Portugal and runs through the Alps before turning south through the Balkans and ending in Cyprus. It makes use of existing routes, including the railway line through the Vouraikos Gorge. That means that with some careful planning, and keeping an eye and ear out for trains, it is possible to take nature walks within the gorge.

The route

The first station north of Kalavrita is Zahlorov. From here we crossed the rail bridge over the river, noting pale speedwell Veronica cymbalaria and Narrow navelwort Umbilicus horizontalis (horizontalis refers to the flowers in this case, not the whole plant) growing from the crevices, and large plane trees Platanus orientalis shading the river valley below. Iridescent blue male beautiful demoiselle damselflies Calopteryx virgo were flitting from leaf to leaf, and showing off in the sun to the iridescent green females.

A road leads uphill from here to Mega Spilio Monastery, which is mostly located in a cave. The rocky slopes supported dry species from the garrigue – Rock bellflower Campanula rupestris, the pink cistuses Cistus incanus and C creticus, and kermes oak Quercus coccifera whose small holly-like leaves host the Kermes scale insect Kermes vermilio. These insects were harvested and dried, then used to produce a crimson dye until the mid-1500s when the cochineal insects were discovered on cactuses in America.

A stream frog Rana graeca was well camouflaged amongst the leaf litter until it moved. We examined it carefully because all the brown frogs look similar – the diagnostic feature here is that the distance between the nostrils is less than the distance between the eye and the nostril!

Closer to Diakopto the land flattens out somewhat to reveal extensive lemon and olive groves. Use of pesticides has meant that native wildflowers have largely been replaced by the invasive Bermuda buttercup Oxalis pes-caprae, but there are still some places with a mass of colour – bellflower Campanula ramoissima, blue houndstone Cynoglossum creticum, bug orchid Orchis coriophoroa, tongue orchid Serapia vomeracea, branching broomrape Orobanche ramosa, birthwort Aristolocia sempervirens, and grass poly Lythrum junceum, to name just a few, and then wonderful fields of scarlet poppies Papaver rhoeas.

Amongst the trees in one field, the dappled sunlight illuminated a patch of bright pink Cyclamen repandum ssp peloponnesiacum – a local speciality – pictured right.

In a nearby ditch we found shepherds needle Scandex pectin-veneris (the common name deriving from the striking seed pods), and also Calabrian soapwort Saponaria calabrica.

Diakopto itself is on the Corinthian Gulf, with maritime species along the shore by the railway line – yellow horned poppy Glaucium flavum, three-horned stock Malcomia tricuspidata, and sea beet Beta maritima.

On the way back to Kalavrita, we had views of a pair of short-toed eagles circling the top of the gorge. A delightful day out indeed.


Bookshop

This is the standard flora for Greece.

First published in 1987, this guide lists many of the richest plant-hunting areas in southeast Europe at first hand, and each description is accompanied by several line drawings.

Names and describes almost 3,000 species of flowering plants in the region.

However, it is a key, and if you prefer to ID your flowers from pictures, then there are other books that might suit better, but are not as comprehensive.

There are some books available that are specific to Greece – this one about bird-watching sites for example.

Most of the ones I have used are now out of print, but the general ones for Europe, shown below, are perfectly adequate.

Note that buying books through these links earns a small commission (at no extra cost to you) that goes towards the cost of maintaining this website.

Pin it for later

One thought on “The Vouraikos Gorge

  1. This sounds so lovely! I would love to do some walking there – for the nature, to be out in the countryside, and especially for the poppies and cyclamen. I remember seeing wild cyclamen on a hike in Cyprus and it made my day.
