Explore Hranice Abyss in 3D – the world’s deepest flooded freshwater abyss
There are some places that few have seen or are yet to be discovered in the Czech Republic. They are hidden underground, created by water over millions of years… gorges, stalactite domes, canyons. Now, thanks to virtual reality and divers’ video recordings, the public has the opportunity to dive into the deep and explore the Hranice Abyss in 3D.
The popularity of the Hranice Abyss’ encouraged the town of Hranice to open a new information center in the former Teplice nad Bečvou station, a 1939 Functionalist building, cultural monument and important example of railway architecture from the first half of the 20th century.
The information center features an interactive 3D model of the Hranice Abyss, capturing the latest knowledge and research on the abyss.
“The abyss is an incredible natural rarity. We wanted to show visitors, using a large 3D model, what is beneath the surface and on the rising slope,” described architect Jitka Mácová.
3D glasses are available to help show various parts of the abyss, especially the places visitors cannot access. The 3D model was created based on videos recorded by the divers between 2000 and 2017, and then assembled with software. There is also a cinema where visitors can view a short film about the abyss.
The cave diving organization ZO 7-02 Hranice Karst, in cooperation with SG Geotechnika a.s., documented the Hranice Abyss through digital aerial photogrammetry using an unmanned aircraft (UAV). They acquired data which aided in the creation of the 3D digital georeferenced model of the abyss’ dry part. As a result, the model has accurate dimensions, inclinations, and articulations of the rock massif.

The Hranice Abyss is truly perilous due to its unique water composition. The ČSS ZO-7-02 Hranice Karst divers recently had to use closed-circuit diving equipment, CCR Liberty by Divesoft, to avoid chemical reactions and impaired visibility. With this equipment, the divers could safely dive 50 meters below.
Just how deep is the Hranice Abyss? The abyss was created atypically by mineral water springs far beneath the surface and therefore, it is not certain where the bottom is, though some theories suggest it could be as far down as 1200 meters. In 2015, divers reached 265 meters.
On the other hand, a recent analysis of the water indicated that there are helium isotopes that rise up from 40 km below. “How the helium gets into the abyss and how deep the water are big unknowns,” the President of the cave diving organization, ZO 7-02 Hranice Karst, Michal Guba, explained.
Some of nature’s secrets are yet to be discovered…
The vistor centre opening hours are Tuesday to Friday from 10 am to 4 pm, and on weekends from 9 am to 5 pm.

Dive Worldwide Announces Bite-Back as its Charity of the Year
Over the next 12 months, specialist scuba holiday company Dive Worldwide will be supporting Bite-Back Shark & Marine Conservation with donations collected from client bookings to any one of its stunning dive destinations around the world. The independently-owned operator expects to raise £3000 for the UK charity.
Manager at Dive Worldwide, Phil North, said: “We’re especially excited to work with Bite-Back and support its intelligent, creative and results-driven campaigns to end the UK trade in shark products and prompt a change in attitudes to the ocean’s most maligned inhabitant.”
Bite-Back is running campaigns to hold the media to account on the way it reports shark news along with a brand new nationwide education programme. Last year the charity was credited for spearheading a UK ban on the import and export of shark fins.
Campaign director at Bite-Back, Graham Buckingham, said: “We’re enormously grateful to Dive Worldwide for choosing to support Bite-Back. The company’s commitment to conservation helps set it apart from other tour operators and we’re certain its clients admire and respect that policy. For us, the affiliation is huge and helps us look to the future with confidence we can deliver against key conservation programmes.”
To launch the fundraising initiative, Phil North presented Graham Buckingham with a cheque for £1,000.
Visit Dive Worldwide to discover its diverse range of international scuba adventures and visit Bite-Back to learn more about the charity’s campaigns.
