Any of the above mentioned tours can be done when you travel with children as long as it is adjusted to their age, specific needs and interests. Some things may be left out, others added. I have guided families with children before and I know how sad it would be to ignore their natural inquisitive nature and make them bored. I am happy to make a suggestion of an itinerary that would suit you. Furthermore I can prepare a quiz for the kids or various tasks for them to fulfil as we tour.
Among the possible things that may be suitably added to the tours or done individually:
– Ride on a funicular to the Petrin Hill and visit the Petrin Tower from where there are magnificent views over the whole city
– Visit of the Mirror Maze which is situated on the Petrin Hill too (great fun for the kids as they walk through a labyrinth of convexe and concave mirrors making them look hilarious), sometimes there is a pony ride available too
– Visit of the Golden Lane (like a fairytale set) and the famous dungeon – the Daliborka Tower situated in the Prague Castle complex
– Visit of the Old Royal Palace where there are copies of the Czech Crown Jewels on permanent display
– Visit of the top of the Town Hall Tower (great views) and the historical underground of the Old Town Hall
– There are numerous marionette stores, in some of them one can buy wooden pieces of marionettes for children to assemble them themselves.
