the cave of horrors...
Gomantong Caves
Deep in the steamy jungles of Borneo, in Malaysia, is a massive crack in the limestone outcrop that leads to an intricate system of caves. Entering the caves is not for the squeamish. In the dank interiors are millions of bats that hang from the roof, while the floor and walls are covered with cockroaches, beetles, rats and other creepy bugs that feast on bat shit and dead swiftlets that fall out of their nests. The caves also house snakes that feed themselves on the rats and cockroaches. The air smells thick with ammonia because of the bird droppings. The guano deposit on the floor is estimated to be 10 feet deep. Wooden walkways through the explore-able section of the caves keep visitors safely above the horrific creatures that litter the ground.
Located on Gomantong Hill inside a protected forest reserve of the Sabah Forestry Department, the Gomantong Caves are the largest caves in the state of Sabah. The caves are best known for their birds' nest which has been harvested for centuries and used in the preparation of bird nest soup.
The swiftlets build their nests almost entirely with threads drawn from their saliva which hardens when exposed to air. Soup prepared from these nests is a prized delicacy in Chinese cuisines due to their rarity, supposedly high nutritional value and health benefits. Some nests also contain foreign materials such as feathers and twigs, and are known as black nests. Both are harvested for consumption, but the purer version fetches a higher price.
Harvesting of birds' nest is now regulated to prevent over-exploitation. Twice a year, from February to April and July to September, licensed locals climb to the roof of the caves and collect the nests only by using rattan ladders, ropes and bamboo poles. The first collection takes place early in the breeding season before the swiftlets lay their eggs. The birds then make another nest in which they finally lay their eggs. After the eggs have hatched and the young swiftlets have abandoned these nests, the second collection is made.
The bulk of the swiftlet nests collected goes to Hong Kong where it is used in soup, drinks, and medicine. The U.S. is surprisingly the second-largest importer of birds' nest in the world. A bowl of bird's nest soup in a nice restaurant can cost as much as $100. A kilogram of white nest can cost up to US$2,000.
Despite the high price, the gelatinous soup is said to be nearly tasteless, with one author describing it as "vanilla banana with stringy noodles".

Jacob’s Well
Jacob’s Well is one of the most significant natural geologic treasures in the Texas Hill Country. It is one of the longest underwater caves in Texas and an artesian spring. Jacob’s Well surges up thousands of gallons of water per minute and acts as headwaters to the Cypress Creek that flows through Wimberley, sustaining Blue Hole and the Blanco River, recharging the Edwards Aquifer, and finally replenishing estuaries in the Gulf of Mexico.

“Fingal’s Cave is a sea cave on the uninhabited island of Staff, one of the Inner Hebrides islands which skirt the western coast of Scotland. The immense arch-roofed cave creates a melodic, haunting echo of waves within its cathedral-like atmosphere; something so impressive Romantic Poets John Keats, William Wordsworth, andAlfred, Lord Tennyson all made journeys here; as well as Her Majestic Queen Victoria. The cave’s Gaelic name is Uamh-Binn, meaning “cave of melody.”
