The Ariadne Karst and Cave Research Grouop has been exploring the caves of the Csévi-szirtek for decades. Their work has resulted in the Ariadne Cave System, which is not only one of the significant cave systems in the Pilis Mountains, but, with its current total length of more than 20 kilometres and a vertical extent of 206 metres, it is the third-longest cave system in Hungary.
As a result of their research, the explorers have discovered connections between ten previously separate caves: Leány Cave, Legény Cave, Ariadne Cave, Rejtekút Cave, Vacska Cave, Indikációs Cave, Kőoszlopos Cave, Hipp-hopp Cave, Gazsi Cave and Gyökeres Cave currently form the system. If the researchers' determination and hard work are accompanied by a little luck, Ajándék Cave may one day become part of the system as well. With its four kilometres of passage and its 3,000-cubic-metre underground lake, it would significantly increase the overall length of the system, while its depth would approach 300 metres.
Exploration is still ongoing, and on Saturday a small team descended into Ajándék Cave. After a full day's work underground, they resurfaced at around 10 PM. After climbing up the hillside to reach the road leading towards Pilis-tető they met a convoy of vehicles arriving. It turned out that the Pest County Search and Rescue Service, civil patrols and the police were starting a joint search operation: a missing hiker was being searched for in the area.
A retired-age woman had become separated from her hiking companion in the twilight and had wandered onto an extremely steep, dangerous hillside. Without a light, continuing to search for a way out would have been dangerous.
The Pest County Search and Rescue Service arrived at the scene with certain tecnical equipment and personnel, including off-road vehicles, a quad and a specialised drone. Their efforts quickly paid off: during a systematic search of the area, they were able to pinpoint the woman's approximate location to within some 200–300 metres.
This was when the cavers, including cave rescuers became directly involved in the operation. One team set off on foot towards the approximate coordinates, while another was taken there on the search-and-rescue team's quad. In the steep and genuinely difficult upper section of the Vaskapu Gorge, they first heard the woman's voice and then found her waiting in the darkness to be rescued.
Having assessed the woman's physical condition and the terrain, and taking into account the recommendations of the search-and-rescue team leader, the team descended with the casualty along the steep, unstable and difficult-to-negotiate trails. From there, things moved quickly: they transported the safely recovered hiker along a track accessible to the quad to the command post, where she was brought to safety. Marika's adventure ended without injury at 12:30 AM.
The cooperation between the Hungarian Cave Rescue Service and the Pest County Search and Rescue Service is about much more than the ad hoc joint operation on Saturday nights. We have been working together for many years and have great respect for each other's work. We have received their assistance on numerous occasions: sometimes their emergency vehicles have helped us reach the scene of an operation, at other times they have helped us set up complete field camp infrastructure during prolonged rescue operations. Most recently, just a few weeks ago, they provided us with Starlink access so that we could remain reachable for an emergency call during our training exercise in the Bükk Mountains.
We are always happy to have them around. On some occasions they have joined us as guests for dinner and a beer; on others, we have had the opportunity to try out some of their new rescue equipments. Many years ao one of their members was laid into our rescue stretcher for a particularly gruelling training exercise.
Although the pleasant early-October weather still brings summery temperatures, the increasingly early sunset tells us that autumn has arrived. For planned hikes, we recommend that you prepare for the early darkness: carry a headlamp with fully charged batteries, and, whenever possible, take a map with you as well. If you plan to navigate using your phone, it is advisable to download a map and an app that can also be used offline. We also recommend carrying a small first-aid kit in your backpack, or at the very least a survival blanket. In an emergency, especially in cool weather, it can save a life – even if you are not the person who has been injured.
And once you have prepared properly, call your friends, plan as many hikes as possible through the beautiful autumn forests, and enjoy being out in nature.
