Camera Obscura and World of Illusions

Camera Obscura and World of Illusions occupies a tall building on Castlehill, at the top of the Royal Mile just below the castle esplanade. The attraction's centrepiece is its camera obscura, which the attraction describes as 173 years old: a system of lenses and mirrors at the top of the tower projects a live moving image of the city onto a viewing table, while a guide picks out landmarks and passers-by. The building itself dates from the 17th century.

Below the camera, several floors are packed with more than 100 interactive exhibits built around optical illusions, light and perception. The exhibits are designed to be touched and played with, which makes them work well for families and groups of friends. At the top, the rooftop terrace on the sixth floor gives panoramic views across the Old Town, Princes Street and the New Town to the Firth of Forth, with the castle close by.

The attraction is open every day, often with long hours from early morning until the evening, but times vary, so check the opening hours page before you go. Tickets are sold for a date and time slot online, and capacity per slot is limited, so booking ahead is recommended, especially in summer. Spare tickets are sometimes sold at the front desk on the day. The attraction asks visitors to book directly rather than through third-party sellers. Allow around one hour and 45 minutes, though you can move at your own pace.

Practical points matter here. There are only stairs between floors, so the attraction is not suitable for visitors who cannot manage steps. Pushchairs and prams must be left in the admissions area, and baby carriers can be borrowed free of charge. Only guide and assistance dogs are allowed. Children aged 12 and under must be accompanied by someone aged 16 or over. ScotRail's Kids Go Free offer can be applied to some off-peak bookings, as explained on the official site.

Camera Obscura suits families with children, teenagers and anyone looking for a light-hearted break from castles and museums. The camera show is best on a bright day, while the illusions work in any weather. It is on Castlehill close to the Scotch Whisky Experience and the castle esplanade, so it combines easily with a morning at Edinburgh Castle and a walk down the Royal Mile.
