The Observatory is an old building, steps at reception cannot be avoided but there is good wheelchair access at the rear of the building.

The hands-on exhibits are in a long wide corridor which is wheelchair accessible. The exhibits themselves are at a low height and accessible. The exhibition in Dome F is accessible.

Dome E housing an historic refractor telescope is accessible during daytime. There are four blue badge parking bays. Blue Badge holders are asked to stop at reception and buy tickets, then drive to the Blue Badge parking area at the rear of the building where there is wheelchair access.

The accessible toilet is on the ground floor and has a height adjustable bed and hoist. There are flashing lights in the separate ‘Light and Colour’ exhibition – there is a warning in place about this on the door.

Quiet days - The Observatory sometimes has quieter days.

These are during term time and on days when there are no pre-booked schools. They are posting on social media to let people know when these are, so it's worth following them if this interests you on facebook or twitter.
