The interior of the Castle remains much as it was when the family last used it.
From the beginning the house was lit by electricity from its own hydro-electric scheme powered by water from a reservoir in Coire Dubh. The internal telephone system was the first in Scotland.
While the castle was being built, George Bullough commissioned Manchester artist George Gordon Byron Cooper known as Byron Cooper, to paint views all round the island and these are hung round the castle. They show the island as it was at the turn of the 19th century. Also throughout are objets d'art brought back from all over the world and also include tarpon caught while on fishing trips.
The guided tour of the castle starts in the Great Hall which is full of furniture and other items from all over the world, watched over by the portraits of George and Monica.
Music could be provided automatically by an electrically driven "Orchestrion" able to produce the effect of a 40 piece orchestra using punched paper or brass rolls. KCFA member Stephen Frankland wrote an article, 'The Orchestrion at Kinloch Castle' in the KCFA Newsletter no 9 of March 2000 which is reproduced with the permission of his widow Frances. KCFA member Douglas King wrote a later report on the condition of the Orchestrion in 2006. The condition of the Orchestrion has deteriorated caused by a woodworm infestation and is no longer in a playable condition. The KCFA have launched an appeal to restore this very rare instrument and we would value your support.
The Dining room, panelled with mahogany, is fitted with the mahogany table and chairs formerly in the Rhouma. The table is overseen by the portrait of John Bullough, over the fireplace.
The Billiard/smoking room is one of the few rooms facing inwards to the central courtyard.
The Drawing Room has a light and delicate air about it and is very feminine showing very clearly Monica's hand throughout in the furnishings, fittings and decoration.
Next to the Drawing room is the Empire Room.
The Ballroom, with its sprung floor, rich yellow damask wall coverings and high windows also faces into the courtyard.
The Library, no longer on the castle tour, was moved to its current position when Monica made alterations and additions to the layout after her marriage to George.
Outside the ballroom is a model of Rum, a object of great interest to visitors.
An oddity, amongst so many oddities, is the dentist's room, in an anteroom by one of the doors. This is a relic of the time after the Bulloughs when the dentist used to visit the island periodically.
Upstairs visitors are shown just two of the bedrooms: George Bullough's room, although this was not actually his room; and Monica's bedroom. George's room was originally in the opposite corner in what is now the manager's flat so all the furniture was moved out.
One of the rooms which used to be available as accommodation was the William Bass room.
Also available until recently for accommodation were three Oak Rooms - these were added by Monica when the castle was enlarged after her marriage to George.
The bathrooms, en-suite in some rooms, are a plumber’s nightmare. The baths incorporate shower enclosures with a complex set of taps to control water which can be hot or cold, come down in a stream or spray, come up in a spray or jet, or even spray in from the side!
