Centre de Geologia de Menorca

The museum answers the question you have probably already asked on the beach: why the sand here looks the way it does. It works up from the rock — what Menorca is made of, and how the coast you have been walking along came to be that shape.

From the square the building looks slight, and then it opens over two floors; an hour is enough to get round both. The interactive exhibits carry the displays for children, the boards are translated into English, and staff answer what the boards leave out.

• An hour covers it. Two floors of displays, and about an hour is enough to read your way round both.
• Toilets on site. There are toilets inside the museum, and none out in the streets around it.
• Set up for children. The exhibits are interactive and part of the display is aimed at families.
• English throughout. The information boards are translated into English, and staff answer questions in English.

Ferreries sits inland, and most visits here are a stop made in the middle of crossing the island. The museum fronts a square in the town centre, with a car park immediately behind the building, so nothing is left on foot once you have parked. Two further car parks lie about 200 m and 260 m away. Coming by bus, the stops are Plaça Príncep Joan Carles, roughly 470 m off, and Ferreries, roughly 510 m, both through the streets of a town small enough to cross without a map.

Best: Tuesday to Sunday, either in the morning or after the museum reopens in the evening. It is all indoors, which makes it the obvious move on a wet or windy day when the coast has nothing to offer.

Avoid: Monday, when it is closed, and the middle of the afternoon, when the doors shut between the two sessions.
