Natural History Museum

Located in Kensington, this museum brims with more than 70 million different specimens and exhibits, from dinosaur bones to a simulated earthquake. The Natural History Museum is also a favorite among families, so you'll find it crawling with kids too. (Likewise, parents should check out an "Explorer Backpack" for kids under age 7; it's filled with activities to keep the wee ones entertained and engaged.)

Recent travelers praise the museum for its free admission and near endless exhibits. One TripAdvisor user says, "I don't know what we expected as it was our first visit but we were there most of the day and returned the following day and still only got a superficial look. It's one of those places that you would return to time and time again." However, because of its popularity, visitors also mention the museum can get overwhelmingly crowded. Prepare for long lines, especially on the weekends. The Natural History Museum is open daily from 10 a.m. to 5:50 p.m. You can find it off the South Kensington tube stop.
