Cherney Maribel Caves County Park is a county park located near Maribel in Manitowoc County, Wisconsin. The park occupies 75 acres along the West Twin River. Cherney Maribel Caves consists of eleven caves along a rugged cliff line that runs parallel with the West Twin River. Maribel New Hope Cave, Tartarus Cave, Sinkhole Cave and Split Rock Cave are all established gated caves that need guides to visit the entire caves, they are gated due to past vandalism to the Speleothems and protect the current Speleothems.

History 
The Cherney Maribel Caves were formed primarily by solution prior to the last ice age. Glaciers wore down the surface of the land and exposed a layer of rock called Niagara Dolomite along the Niagara Escarpment, exposing crevices and sinkholes, allowing water to easily enter the caves. As the glaciers melted, the rushing water enlarged the existing caves, and later partially filled them with silt and gravel as the flow of water receded.  The rushing melt water also carved the river valley.  Since then, frost action has loosened rock from the cliff face, partially to fully closing the cave entrances.

About 1892, the first of the caves were discovered on the property of Henry A. Alrich, and was soon purchased by Charles Steinbrecher, who, in 1900, built the nearby Maribel Caves Hotel. Over the next several decades, tourists came to see the caves. In 1931, Adolph Cherney bought the property, including the nearby hotel. On November 5, 1963, Cherney sold the cave property to Manitowoc County for $16,200, leading to it becoming the first Manitowoc County park.

Spring Cave 
Spring Cave is a small inaccessible cave located on adjacent private property. A natural spring that flows from the cave was previously used by the nearby Maribel Caves Hotel. This cave is on Private Property and can only be viewed by the viewing deck on Manitowoc County Property.

Maribel New Hope Cave 
Maribel New Hope Cave is the largest cave in Manitowoc County. It was discovered on Sunday, February 5, 1984.  It is noted for its walking passageways, and is lighted by electric floodlights. It contains examples of stalactites, stalagmites, Helictites, and cave bacon. The cave is a public show cave.  It is open the 3rd Sunday of every month from May through October from 10 am to 3 pm for public tours.  The cave is still being excavated and explored further by members of the Wisconsin Speleological Society. College instructors use this cave as a living laboratory.

Aguaduice Cave
Aquadulce Cave was discovered in 2003 by Wisconsin Speleological Society members, its a smaller crawling wild cave that currently has about 30ft passage that goes northwest and then curves to the left going west. Aguaduice is situated a ways off the banks of the West Twin River in the Wisconsin State Natural Area of Cherney Maribel Caves County Park. Aquaduice cave is located in the escarpment ridge that runs the length of the park measuring about sixty feet in height above the river bed. The entrance to the cave is almost at the top of the bluff line along the park bluff and is not easily reached, Aquaduice cave is probably the hardest to access being there is a 8ft pit to crawl into first before reaching the floor of the cave . Aguaduice Cave is Spanish  for freshwater, literally meaning Sweetwater.

Pancake Cave 
Pancake Cave is difficult to reach because no trails lead to it. The cave is about eight feet deep and is shaped like a pancake.

Coopers Cave 
Coopers Cave is located about midway along the park bluff. The cave has a large rectangular entrance and also has a small crevice entrance. It is a square tube solutional cave that is quiet and dry. About nine feet below the entrance is a natural spring that flows year round into the West Twin River.

Staircase Cave 
Staircase Cave is a small relatively inaccessible cave.

Split Rock Cave
Split Rock Cave was discovered in the winter of 2008 by Wisconsin Speleological Society members on a -22deg below zero winter day noticing steam coming out and feather frost brimming at the entrance of the cave. Split Rock Cave today is part of the Tartarus Cave System, this cave is a all hands and knee crawling except for a few  sit up areas with domes.

Tunnel Passage 

Tunnel Passage, discovered in 2005, is about 20 feet long and approximately three feet in height.

Tartarus Cave System 
The Tartarus Cave System is a large system of caves in the park that is still being excavated. It has three entrances: Tunnel Passage Entrance, the Tartarus Cave Entrance, and the Split Rock Cave Entrance.

Cave of Treasures
Cave of Treasures is located to the south just beyond the Tartarus Cave System in the same bluff.  It is the most recently discovered cave by the Wisconsin Speleological Society.  It consists of a three to four foot high horizontal entrance, that leads to over 70 feet of hands and knees crawlway passages.  It is believed that further excavation, or digging, will open up passageway continuations so it will eventually connect it up to the Tartarus Cave System just to the north.

Sinkhole Cave
Sinkhole Cave is located to the south of Cave of Treasures above the bluff line, it is the currently the only cave in the park one has to rappel into.

Features 
The park offers a playground, a picnic area, and hiking and biking trails. A picnic shelter with bathrooms is located in the picnic area. Along the cliff line are several varieties of rare ferns, along with creeping plants and wild flowers. The beauty of the area made it a popular tourist destination even before Manitowoc County acquired the property in 1963.

2013 Tornado 
In August 2013, a tornado ripped through Cherney Maribel Cave County Park. It destroyed more than 75 percent of the trees, the picnic shelter, and the restrooms. The restrooms and picnic shelters have since been rebuilt, one on south end of park called the Tartarus Pavilion with flush facilities and other on north end of the park called the New Hope Pavilion with pit facilities.
