Caves, Dong Hoi

The Marble Mountains are a cluster of five hills made from limestone and marble in Da Nang. It's also a well-known pilgrimage site with peaks, caves, tunnels and temples all just waiting to be discovered. Named after the elements metal, wood, water, fire and earth, Marble Mountains exist in a coastal area that is renowned for stone-cutting and sculpture about 9km south of Da Nang. The caves within the mountains hold many secrets including bullet holes from when troops used to spy on the US soldiers relaxing on My Khe Beach below and buildings standing within the caves and grottoes. There are also Buddhist sanctuaries and places of worship dotted across the mountains which are a much-visited spiritual site. You can even see a special circular cave here. It leads to the summit, where you can enjoy spectacular panoramic views. http://www.vietnam-guide.com/da-nang/marble-mountain.htm

The Perfume Pagoda, known locally as Chua Huong or ‘inner temple’, is at the centre of a very revered and sacred site featuring a maze of mainly Buddhist temples built into the limestone cliffs of Huong Tich. At the heart of this complex lies the Perfume Temple or Perfume Pagoda in the Huong Tich Cave. It is believed that the first temple was built here in the 15th century, although legend declares that the site was actually discovered over 2,000 years ago by a Buddhist monk who was meditating nearby. The mountain foothills are an area of great natural and spiritual beauty filled with streams, tropical plants and temples. There are many pagodas to visit, each offering a different shrine, most of which are Buddhist although one or two are animist. The Perfume Pagoda attracts pilgrims and tourists seeking good luck from the stalagmites and stalactites inside the cave which have been named according to the individual blessing they can bestow. Dun Tien offers prosperity and Nui Co offers the chance of giving birth to a girl whilst Dun Gao translates as a ‘rice stack’ to those hoping for a bountiful harvest. http://www.vietnam-guide.com/hanoi/perfume-pagoda.htm

John Gray’s crew cares about you and nature; they speak a decent to exciting English and will tell you a lot about what you are about to see and discover. Boats never get crowded, and food on board is excellent. You’ll be asked to respect Nature around you as much as they do, which means no touching, no loud talking and of course no smoking while you are exploring the famous ‘Hongs’ (enclosed lagoons, usually only accessible through a narrow tunnel when tides permit). They also try to avoid crowded places: a Hong with a hundred canoes in it is not exactly a grand vision of nature at its best. On the way, you will be amazed to see the size and the amount of these fantastic limestone formations rising straight up from the sea and covered with dense vegetation. While moving from one island to another, the crew will throw some chicken bits in the air, and dozens ‘Bramany Kites’ (some Sea Eagles) will flock and dive behind the boat. https://www.phuket101.net/kayaking-in-phang-nga-bay/

Located in the Maros regency in the province of South Sulawesi, the Bantimurung Bulusaraung National Park is a mere 50 km from Makassar or 20 km from the Sultan Hasanuddin international airport. The Bantimurung National Park has a total area of approximately 43,750 hectares and is divided into three major types of ecosystems, namely the karst ecosystems, a lowland forest ecosystem, and a lower montane forest ecosystem. The valleys of limestone hills and steep karts walls with tropical vegetation have made Bantimurung an ideal habitat for various rare and endemic species of butterflies, birds and insects. Although there are not as many butterflies today as there were during Wallace’s expedition, visitors can still observe the wide variety of butterflies within the Butterfly Conservation Captivity managed by the Center for Butterfly Breeding. Within the national park, visitors can also find a butterfly museum which houses thousands of unique and rare butterflies that have and still inhabit the area. By the butterfly center, the fascinating Bantimurung waterfall draws visitors with its powerful rush of water and refreshing atmosphere. This is a favourite holiday destination, especially on weekends. https://www.indonesia.travel/gb/en/destinations/sulawesi/makassar/bantimurung-bulusaraung-national-park

The salt mining is located about 2 km from the city, in the salt massif of Valcele – Slatinele, at 240 m depth and represents, by the microclimate of salt, an important natural factor of cure used to treat respiratory diseases. The main feature of the microclimate of the mine is the constancy of physical, chemical and microbiological parameters (without daily or seasonal variations), unlike outside air. The climatic parameters of Romanian's salt mining are temperature( approx. 12 ° - 13 °), relative humidity (approx. 60-80%), airflow speed reduced (almost imperceptible), air pressure is similar to the outside pressure or with little difference. http://www.uvisitromania.com/tourist-attractions/bacau/salt-mine-of-targu-ocna-id573

The Abbey Caves Reserve comprises of naturally sculptured limestone outcrops, bluffs, enclosed depressions, sinkholes and three significant caves, Organ, Middle and Ivy. Two distinct areas of native bush with well established podocarp-hardwood forest include particularly fine specimens of puriri trees. Nathaniel and Amelia Clotworthy settled on 409 acres here in about 1860. Their house in the limestone outcrops resembled an Irish ‘abbey’ leading to the name. The house was destroyed by fire in 1920 but the site is still marked by chimney remains. A grave of one of the Clotworthy children also remains from 1884. The land was bought by the Golden Bay Cement Company as a site to establish a mine, but in 1989 they sold it to the then City Council as a reserve for the people of Whangarei. http://www.wdc.govt.nz/FacilitiesandRecreation/WalksTrails/Pages/AbbeyCaves.aspx

Spread over an area of approximately 15,000 m2, the Exotic Garden is home to a thousand cacti and other succulent plants with stems or hypertrophic leaves which store water. Originally from the planet’s main semi-arid regions, these plants still produce plenty of flowers. The principal flowering seasons are winter (January–February) for South African succulents such as Aloe and Crassula, and spring and summer for cacti, a family native to the American continent. The enormous trees which line the paths of the Exotic Garden illustrate the age of the collection which served as the basis for the creation of the garden at the instigation of Prince Albert I. Opened to the public in February 1933, and supplemented in the 1960s by a botanical centre and specialist tree nursery, the garden is one of the Principalities most visited tourist attractions. At the base of the cliff on which the Exotic Garden is situated (called “the observatory” due to the long-standing presence of a small astronomical observatory), at an altitude of 100 metres, there is a subterranean chamber equipped to receive visitors. The limestone rock, carved out by water containing carbon dioxide, is studded with caverns adorned with geological formations bearing evocative names: stalactites, stalagmites, draperies, columns, soda straws... Expert guided tours of the cave are included in the entry ticket for the Exotic Garden. The tour travels from a depth of 98 metres to a depth of 40 metres (around 300 steps). The chamber plunges down almost to sea level and is regularly explored by local cavers. The presence of prehistoric humans in the region of the cave is confirmed by the bones of the animals that they ate. These remains also illustrate the climate variations that have taken place over the last 250,000 years. http://www.visitmonaco.com/en/Places-to-visit/Gardens/The-Exotic-Gardens-and-the-Observation-Cave

The limestone of the Picardy plateau was dug out in many places to form refuges. These refugees were called "muches" (hideouts in Picard language). Those in Naours, rediscovered at the end of the last century, are the largest known: all the underground areas combined can house around 2,600 people with their livestock. The layout is remarkable: around 300 chambers, public squares, stables, wells, chimneys, and a chapel with three naves. These underground areas were used by the British forces during the First World War and were used as the headquarters of the German forces during the second world war. Exhibitions of traditional trades. In the park: games, 2 windmills from the 18th century. http://www.visit-amiens.com/tourinsoft/details/en_patrimoineculturel/PCUPIC0800010624/PCU

Due to its position on the Mid-Atlantic ridge, Iceland is one of the most active volcanic regions in the world. Its unique geological conditions make for some awe-inspiring rock formations, both beneath the surface as well as above it. Various tube caves—formed by magma flowing underneath the earth's surface after lava has solidified overhead—can safely be explored through guided excursions year-round. For safety reasons, different caves are explored during different seasons. The most commonly visited caves are the Gjábakkahellir Cave near Þingvellir National Park in the summer months, and the Leiðarendi Cave in the Bláfjöll area in wintertime. https://www.inspiredbyiceland.com/things-to-do/activities/caving/
