Extensive archaeological work since 2000 has confirmed that people lived in the Szalajka Valley as early as 40,000 years ago. The cave dwellers lived in the Istállós cave and even had contact with other tribes from the valley, some of which lived 500 kilometers away. People also lived in the idyllic valley during the Bronze Age, as evidenced by Celtic relics and an early earthwork. Nevertheless, there were no major settlements within the valley until the Middle Ages, as trade routes were difficult to establish in the heavily forested area. Continuous settlement in the Szalajka Valley began in the 14th century, when people settled in the village of Wárad, now known as Szilvásvárad. The high-quality timber served as a source of urban income even in the Middle Ages, leading to increasing numbers of settlements.

Accessing the cave from the parking lot in Újmassa is an easy task, by turning right at the trout hatchery and following the red + sign, the destination can be reached after approximately 1 hour and a 140-meter elevation gain. Going down to the cave can be dangerous in wet weather, because the road is slippery and steep, hiking boots with a tight ankle grip and non-slip soles are highly recommended.

This is Bükk's only intermittent spring (katatovra): sometimes it works as a source, sometimes as a sink.

Suba-lyuk prehistoric man’s cave. A must see in the Hór valley. Whilst the walk up to the cave is short, it’s also steep and rocky.

While many caves are well-known, the Bükk Mountains contain over 1,000 caves, meaning many are undeveloped or less frequently visited.
