The tramway operates on a one-meter gauge track. Originally, steam locomotives were used, but from around 1934 diesel trams were introduced and are still in use today. The tramway serves tourist purposes and connects the village center of Han-sur-Lesse with the cave entrance, providing visitors with convenient access to the stalactite cave. The route is currently about 3.1 kilometers long.

This large cavity extends deep into the limestone rock (beautiful layering). Former outlet of the Lomme River, today about ten meters above the riverbed. A stunning resurgence that brings an underground river back to the surface.

The Caves of Han owe their shape to the Lesse, the river that flows through them. The water has eroded an extensive cave system from the limestone, making it one of the largest in Europe. The caves have been used since time immemorial: from prehistoric shelter to the tourist attraction they are today.

Most major show caves in the region, such as the Han Caves and Grotte La Merveilleuse, maintain a relatively constant cool temperature (around 10-15°C) year-round, making them suitable for visits in any season. However, the surrounding natural parks and outdoor activities are often best enjoyed during spring, summer, and early autumn when the weather is milder.
The Houyet region offers numerous outdoor activities. You can explore hiking trails ranging from moderate to difficult, or enjoy cycling routes along the Lesse River. There are also various running trails available. The Furfooz Nature Park, for instance, combines caves with scenic walking paths.
To reach the Han Caves, visitors typically take a historic tramway from the village of Han-sur-Lesse to the cave entrance. Inside, a guided tour leads you through vast chambers with impressive geological formations and a spectacular sound and light show in the Salle d’Armes. The Lesse River also flows through parts of the cave.
Given that caves maintain a cool temperature year-round (e.g., Lorette-Rochefort Cave can be 2-13°C), it's advisable to wear warm layers, even in summer. Comfortable walking shoes with good grip are also recommended, as paths can sometimes be damp or uneven. For caves like Gatte d'Or Cave, a flashlight is essential for darker passages.
The Grotte La Merveilleuse in Dinant offers a self-guided experience, allowing visitors to explore at their own pace. Most other major show caves, such as the Han Caves and Lorette-Rochefort Cave, typically require guided tours to ensure safety and provide interpretive information.

The Gatte d'Or Cave is particularly enjoyed for its adventurous, family-friendly exploration.
While the major show caves are well-known, the Furfooz Nature Park offers a chance to discover several smaller, more intimate grottoes and caves like the 'Trou du Grand Duc' or 'Trou qui Fume' within a beautiful natural setting, providing a different kind of underground exploration alongside historical ruins.
