Stala‘c’tite from the ‘c’eiling, stala‘g’mite on the ‘g’round. This mnemonic can help you to identify the wonderful stone formations at the Lurgrotte, Austria’s largest dripstone cave. Here calcium mineral deposition over millions of years has yielded enchanting natural artworks both fragile and massive, with fantastic names meaning prince, giant and grand candle stick. You can explore this fascinating cavern complex accompanied by an expert guide, starting from either Peggau or Semriach. The first person daring to enter the depths of Lurgrotte was the Italian cave scientist Max Brunello. In 1894 he discovered the Great Dome. This huge hall with an area of 120m by 80m and a height of 40m is among the biggest of its kind in central Europe and can be reached from the Semriach entrance. During guided tours a special atmosphere is created in the chamber by dramatic sound and lighting effects. Along the approximately 2km trail accessible from Semriach you can marvel, for example, at the forty-ton "giant" being probably the thickest hanging stalactite in the world. https://www.graztourismus.at/en/see-and-do/sightseeing/trips-around-graz/lurgrotte-cave-peggau_af-1213

The countryside immediately around Graz is wild and romantic. Among the natural attractions hidden away here are narrow gorges and gullies, through which busy streams rush. The beautiful Kesselfallklamm is like a little sister to the mighty Bärenschützklamm. Well secured steps allow you to explore this romantic gully comfortably with children too. At its northern end is the town of Semriach, a health resort popular for its air quality and treasured as a wonderful patch of Styria. The Kesselfall gorge, the most spectacular section of the Rötschbach stream, has been accessible since 1904. The Kesselfall circle trail (R3) starts at the Sandwirt restaurant in Augraben. A pictorial sign will show you the way: a man falling into a pot (Ger. "Kessel"). Fresh from the spring, the water rushes and roars over waterfalls, in rapids and through pools. From the highest of the falls, the water plunges in cascades over a 38m drop. Thanks to more than 50 ladders and bridges, in all, about 1,800 rungs, you can experience this marvel up close. On the upper reaches of the gorge, where the Rötschbach stream is silently murmuring, the circle trail turns to the right. Walking steeply uphill, you will first reach an unusual rock formation called "Stone Gate" and will pass a cave, before going downhill and finishing the tour in the valley at Sandwirt. In one and a half hours of walking you would have covered 2.7 km and an altitude difference of 200m. https://www.graztourismus.at/en/see-and-do/sightseeing/trips-around-graz/kesselfallklamm_af-1272

At 1445 metres not exactly the highest, but the Schöckl, local mountain of Graz, is an extremely popular destination.

In terms of its geology, the Schöckl is a limestone mountain with a core of crystalline rock. At the interface of permeable and impermeable rock, springs come to the surface. Thanks to radioactive springs and healthy air, the village of St. Radegund on the southern foot of Schöckl became an internationally renowned spa in the 19th century. https://www.graztourismus.at/en/see-and-do/sightseeing/trips-around-graz/schockl-mountain_af-1271

Originally a spacious park irrigated by natural resources, it was once a favourite popular meeting point, although today it occupies a smaller area due to the construction of buildings that have been constructed around it in its surroundings over time.

Apart from Mlaka Park, Nikola Host’s Park is one of the oldest in Rijeka.

Located on the rocky terrain and stretching over several levels, the park, with its sculptures, fountains and exotic plants brought by the archduke from around the world, has assumed the appearance of an English garden. This appearance has partly faded away over time. The park was named after the Austrian botanist who participated in its creation.

Near the road Rovinj-pula, about 2 kilometres far from the centre of the City of Rovinj, in the locality of Monfiorenzo, is situated the quarry phantasy, a geological park of remarkable beauty and importance. According to the expert opinion of numerous scientists, it is one of the most significant natural monuments in the world in the perspective of the karst phenomenon. The lime-stone of the quarry phantasy, like the open book pages, illustrate the history of the evolution of the terrestrial crust. Various layers give evidence of the existence of the fossilized meadows consisting of sea-weeds, which, blended with lime-stone silt, were drifted on the shore by strong currents during the last 130 million years. The quarry phantasy will reveal to a more careful visitor a considerably big number of furrows made of black and white dolomiti layers. Furthermore, there are fissures formed by tightening and exsiccation of the silt that had been squeezed into the previously created sediment. The lower part of these stony layers was formed below the sea level, while the upper part is the result of the high-tide. https://www.inforovinj.com/eng/rovinj/znamenje/monfiorenzo.asp

On the west side of the Old Town core lies the Monte beach. For those who find accommodation in the Old Town, this beach will only be a few minutes walk away. This is also the ideal place for visitors who start touring the Old Town – they can find relief from the heat in the Rovinj sea. Although the beach is about 150 meters long, the locals divided it into several parts. The Big and Little Guguliera are small beaches, suitable for bathing small children, while Baluota (or Balota) and Lanterna are beaches favoured by the older population (you get into the sea by climbing down or diving from the rocks). Many cafes and restaurants are a few dozen meters away from the beach, while the XL café and Monte restaurant are situated at the foot of the St. Euphemia church (about 50 meters from the beaches). The beaches are rocky, with no natural shade, so we recommend bringing along some refreshing beverages and headcovers. When the gale gets strong, the waves will make it even more difficult to get into the sea or out of it, so it is better to go for the beaches in one of the numerous Rovinj coves when it is windy. https://www.inforovinj.com/eng/rovinj/plaze/monte.asp

The forest park Punta Corrente (Golden Cape) is one of the most important natural attractions of Rovinj.

His premature death interrupted the realization of this ambitious project, but his vision remained and contributed to the development of tourism in this area. The uniqueness of Punta Corrente has been recognized in 1961 and declared a nature park. Golden Cape is ideal for various sporting activities such as running, cycling, gymnastics. The old quarry has been transformed into a paradise for lovers of free climbing. The park is perfect for a leisurely stroll. The whole area is closed to traffic from motor vehicles.
