London with Kids - The Best TOURS & THINGS TO DO
"One of the world’s best museums has a kid-friendly attitude and fun children’s audio tours. The Rosetta Stone, the Elgin (Parthenon) Marbles, and the Egyptian mummies are some of the jaw-dropping exhibits. To keep them even engaged, download activity trails to your smartphone or tablet, or print worksheets before you go."
