Here's a fun, balanced 3-day family itinerary for children aged 7–14 in London. It mixes history (castles, crowns, ancient stories), culture (museums, markets, royal vibes), and exciting adventures (high views, boat rides, bridges with thrills, dinosaurs, and interactive fun). The plan keeps walking manageable, includes breaks, and uses London's excellent public transport (get an Oyster card or contactless payment for tubes/buses). Most major attractions are open daily in 202
