Hinagdanan Cave is made of limestone. Its entrance is a hole about 1 metre in diameter, visible from a limestone hill. Cement steps lead to the interior. The cave is slippery, but there's a rope railing to hold on to. The cave is filled with sleeping birds in small holes in the ceiling. The sunlight that enters the cave make it unsuitable for bats.
Hinagdanan Cave was accidentally discovered when the area's owner was clearing decaying branches. He threw a stone into the hole and heard a splash. After building a ladder to enter the cave, he named it Hinagdanan ("laddered").
The cave is about 100 metres long, with many beautiful stalagmite and stalactite rock formations. There is a lagoon with a green hue produced by the green limestone at its bottom. People used to bathe there, but it is no longer advised due to karst pollutants in the water.
A stalactite is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite. Stalactites may be composed of lava, minerals, mud, peat, pitch, sand, sinter, and amberat. A stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves.
A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat.
A speleothem is a geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies.

Cave of the Mounds, a natural limestone cave located near Blue Mounds, Wisconsin, United States, is named for two nearby hills called the Blue Mounds.

The Chicago Academy of Sciences considers the Cave of the Mounds to be "the significant cave of the upper Midwest" because of its beauty, and it is promoted as the "jewel box" of major American caves. In 1987, the United States Department of the Interior and the National Park Service designated the cave as a National Natural Landmark.

The caves of Aruba, located on the windward side within the Arikok National Park, comprise notable formations such as Quadirikiri Cave, Fontein Cave, and Huliba Cave. These subterranean environments serve as habitats for a variety of nocturnal bats, including insectivores and frugivores. The presence of these bats species is of ecological importance, contributing to the preservation of Aruba's biodiversity. Their role in controlling insect populations and aiding in pollination underscores their significance within the island's ecosystem.

Hup Pa Tat is a valley located in Uthai Thani Province in Thailand. There is an abundance of exotic plants, such as Arenga Pinnata. The plants expand wildly in the cordon of stalagmites and stalactites. During the visits, rare animals like elongated tortoises and pink dragon millipede might be found. The valley is located in Kao Huai Sok, one of the mountains in a limestone mountain range, comprising an area of about 48,000 square meters. A long time ago, this was an enormous cave until the ceiling collapsed. Major limestone blocks scattered on the floor of the valley confirm this theory. Surrounding by limestone mountains, the sunlight is restrained from reaching the ground during any time than midday. The place was discovered by a local monk in 1979. Later in 1984, the mountain has been blasted to make convenient access to the valley.
