The Espai Cràter is a semi-buried building with two floors. It can be accessed from Carrer Macarnau (access by ramp), or Carrer Roser, next to the bullring (access by lift or stairs).

The centre has two floors. On the ground floor, there are several spaces:

• Hall: entrance space, with double doors. Accessible from Carrer del Roser and Carrer Macarnau. It is the centre for information and distribution of the centre’s activities.
• La Cambra: this is the room that houses the permanent exhibition on volcanology. It is accessed from the lobby, through a first room where an introductory audiovisual is projected.
• Sala Magma: this is an auditorium format room. It has a stage, 110 fixed seats, a control booth, and a dressing room. It is accessed from the foyer. It hosts its own activities and those of other entities.
• Aula Bufador: this is a multi-purpose space where educational activities and family workshops, among others, are held. It is accessed from the foyer.

In the attic, we can find:

• Zona Sísmica: accessed by a staircase through the lobby or by lift. This is the office area, closed to the public. It also houses the Documentation Point of the Natural Park of la Garrotxa (by prior reservation). It has a meeting room, toilets, and a small kitchen.

Pets are not allowed inside the exhibition, except for assistance dogs.

A wheelchair loan service is available free of charge. It can be requested at reception.

The toilets of the Espai Cràter are located on the ground floor, near the reception. They are accessible to people with reduced mobility and do not distinguish between genders.

The lift is located next to the reception and connects the two floors of the Espai Cràter with the urban park, located above the building. To access from the outside, it is necessary to ring the bell. All floors are also connected by stairs.

There are eight rest areas along the route of the permanent exhibition. They are in the main foyer, in the introductory video, and in the exhibition hall.

We have a baby changing table. It is located in the toilets on the ground floor.

The exhibition room is artificially lit. They are dark areas, without much contrast. If necessary, support can be requested from the centre’s staff.

On busy days, ambient noise in the foyer and exhibition hall can be loud.

The reception is located to the left of the door, for access from Carrer Macarnau, and to the right, for access from Carrer del Roser.

The reception has a double-height counter. There is no routing surface. The staff is uniformed, with a black and white waistcoat.

In the hall, there is a reading point with local magazines related to the Espai Cràter.

The Espai Cràter has free internet access for all visitors. To access it, you need to scan the QR code that you can find at reception.

In the lobby there is a family corner designed as a relaxed space for children to experiment freely.

There is a cabinet with stories, magazines, books, and games selected by the Documentation Centre of the Garrotxa Volcanic Zone Natural Park. There is also a table with blank sheets of paper, volcanic drawings to colour, and felt-tip pens.

Next to the reception, there is a locker service that can be activated with a one-euro coin. There are also hangers for coats and jackets.
