The characteristic sights of the valley and its many natural wonders reveal the Vipava Valley is part of the karstic world – the Kras, which thrills with its unusual geologic phenomena. Come and see them from up close! Lovers of hiking can ascend to the edge of the Trnovo Plateau, admiring the natural bridges Otliško Okno and Skozno with their breathtaking views through a natural window formation in the rock. Picturesque marvels are also the karstic river springs of the Valley's two rivers: the mountain spring of the Hubelj River turns into a proper attraction during rainy season, while the twin source of the Vipava River is known as Europe's only existing deltoid spring. Just half an hour's ride away, you can descend into the magical domain of one of the world's most renowned karstic caves, the Postojna Cave, the most frequently visited tourist cave on the old continent, where an electrical train ride will take you past great halls of stalagmites and stalactites, introducing you to the secret, wonderful and unique creature – the Human Fish found here and nowhere else on the planet. The Škocjan Caves, part of the UNESCO list of world heritage with their magnificent underground canyon and vibrant surrounding nature, are another pearl of the Kras. Exploring the caves presents adventurers with the mysterious connections between the subterranean world and the abundance of pristine drinking water in the Vipava Valley.

In the summer heat the locals like to ascend the Nanos Plateau, the Gora Plateau or the Trnovo Forest. Tall plateaus overlooking the valley welcome visitors with notably lower temperatures and delight with their green, blossoming landscape. At the summer's peak, a trip across the Trnovo Plateau is simply a must. You can start the adventure in Ajdovščina, riding along one of Slovenia's most picturesque mountain roads, arriving through tunnels of rock to the edge of the Gora Plateau, a place of uplifting views over the land. Then, on to the Trnovo Forest to see the frozen entrance to the Great Ice Cave and its curious vegetation inversion. The entrance is pleasantly chilly, freshening you up before you continue. At the other end of the Trnovo Forest, the sunlit meadows of the Banjška Plateau await, inviting to a leisurely stroll far removed from the noisy world. From there the way descends back into the valley, to Nova Gorica where you can decide to explore the Soča Valley by passing the fabled Solkan Bridge and its massive stone arc. The river beauty in the westernmost part of Slovenia impresses with its fascinating emerald colour, crystal clear pools and variety of sports and outdoor adventures.
