Líthica, Pedreres de s'Hostal

The walls do it. You walk between faces of sawn sandstone that rise like the sides of a house, and then the chamber opens and another one begins behind it, and somewhere in the middle of that you stop knowing which way you came in. Getting lost is more or less the point, and the markers on the paths are there to be found again.

In the older workings the floor has gone to garden: local plants, water features, a labyrinth cut into the rock. The amphitheatre is carved from the same stone and used for concerts, and people time trips around the summer programme. Two hours in, there will still be corners you have not walked.

• Book ahead. Time slots are sold online, and holding one keeps you out of the queue.
• Carry water. There is no public drinking water nearby; the small shop on site sells drinks and handmade goods.
• Allow the time. The longer route runs to about two hours, and it is easy to spend that and still leave corners unseen.
• Children do well here. Mazes, gardens and stone rooms to explore, and there are toilets on site.
• Sunday is a half day. Plan a Sunday visit for the morning.

The quarry lies on the western edge of Ciutadella. Parking is free and close: two car parks sit about 143 m and 167 m from the site, and a map board for the botanical circuit stands within about 120 m, which is where the route through the workings starts to make sense.

By bus it is a longer business. The nearest stops, Sabaters and Ecoparc, are roughly 1 km and 1.2 km away in a straight line. Within about 400 m an information board marks the Montefi Necropolis, worth a look if the prehistoric side of the island is also on the list.

Best: first thing in the morning, while the stone still holds the night's cool and the paths are empty.

Avoid: the middle of a summer afternoon, and Sunday afternoons, when the quarry is shut.

Heat decides it. A July morning here is quiet and comfortable, and the afternoon heat creeps into the open chambers. In summer the cubical amphitheatre hosts the Fosquets de Líthica concert series, which is worth checking against your dates if music in a stone room is part of the draw.
