The Grotta di Castello Tesino is developed as a show cave with paths, but it has no electric light. The light is provided by the guide, who also provides helmets. But as the cave tour is rather rough, old clothes, rubber boots and working gloves, are a good idea.
The natural entrance of the cave opens onto the gravel bed of the Senaiga torrent. But this entrance is flooded most of the time. Nearby an artificial entrance was built, which is accessible all the year.
The tour shows the first part of the cave to the first siphon.
