The Punkva River flows into the abyss and disappears into the bottom lakes before resurfacing further downstream.
The abyss floor is home to rare plant species that thrive in the specific light and moisture conditions of the sinkhole.
The name 'Macocha' translates to 'Stepmother' in Czech, derived from a 17th-century local legend.
The first recorded descent into the abyss occurred in 1723 by Lazarus Schopper.
The sinkhole is part of a larger karst system containing over 1,100 caves.
Professional cave divers have mapped over 30 kilometers of tunnels connected to the Macocha system.
The Macocha Abyss is a 138.5-meter deep limestone sinkhole located in the Moravian Karst region of the Czech Republic. It is part of a complex cave system formed by the collapse of a massive subterranean chamber ceiling. The abyss features two distinct viewing bridges: one at the top edge and one located 92 meters below at a mid-point shelf. An underground river, the Punkva, flows through the floor of the abyss and feeds two small lakes. The site is physically linked to the Punkva Caves, allowing visitors to tour the underground passages and navigate parts of the river by boat. The abyss is the largest of its kind in Central Europe by depth. It is situated within a protected landscape area, preserving unique microclimates and karst flora.
The 'Upper Bridge' offers the most comprehensive vertical view of the entire depth of the abyss.
Combine your visit to the abyss rim with a pre-booked boat tour of the Punkva Caves to see the bottom from the water level.
Bring a light jacket as the temperature inside the connected cave system remains low year-round.
Wear shoes with high traction, as the paths near the abyss rim and cave entrances can be slippery.
Attempting to hike between the abyss and the cave entrance without checking the specific trail terrain, as it is a steep, forested incline.
The boat transport component is generally closed during winter months or during periods of high water levels in the Punkva River.
Maintain silence inside the cave system; flash photography is permitted, but do not touch the stalactites.
