London Guided Tours for the most popular attractions

London Walks has many excellent tours. I’ve taken most of them over the last 30 years. While most of the tours are outside, they have a few that focus on a particular museum.

The British Museum offers several tours. I took the Around the World in 90 Minutes tour last March. It was a great way to see and learn about the highlights of this crowded and loud museum. It was well worth the price. They offer several other tours including some before regular opening hours. Your free to explore on your own afterwards.

The V & A offers several free tours throughout the day. I took the Highlights of the V & A. What you will see is left up to the volunteer guide.

My Verger Tour at Westminster last spring was excellent.

Beefeater tours of the Tower of London are included in your ticket - no advance tickets or tickets at all since it is included. Just join a group at the meeting point.

It is a wonderful introduction to the Tower. enjoy.

I'd be very surprised if there are any tours of the Churchill War Rooms; the quarters there are very tight. Use the audio guide for the war rooms part of the attraction, which doesn't take long to see. The big time sink is the Churchill Museum section. I don't remember whether the audio guide covers that; it has lots of posted info and videos. A full visit to the Churchill War Rooms will take over half a day if you want to read/absorb all the information.

You might also be interested in the Imperial War Museum (which is free/donation-requested, unlike the pricey Churchill War Rooms). Before I went to the IWM, I assumed it was all about war materiel, which is really of no interest to me, but its exhibitions are very well explained, with the (similar) explanatory material available both in posted form as well as via an audio guide (for which there is a fee). There are usually also one or two small special exhibitions, and I've found those very interesting as well. The IWM, like the British Museum and the V&A, will take multiple visits for complete coverage. If you don't have that much time or interest, it's a very good idea to check out the museums' floor plans ahead of time to figure out where to focus your attention.

I took a London Walks tour of the British Museum a few years ago. It was a good tour (the company's guides do a great job), but even a London Walks tour guide couldn't avoid the massive crowding in the British Museum (especially on the first floor).

As regards the Churchill War Rooms the IWM does offer their own guided tours before public opening times at 8.45 and 9 am, bookeable until March 2027, £54 a person.
Also private behind the glass, touch the exhibits tours for £600 in opening hours or £700 before or after hours, book by e mail.
I know that is expensive, but you asked for information, so that is what is available.

Thanks, isn31c. I didn't know about those tours. They're out of my price-range, but for folks uncomfortable in crowded conditions and with a strong interest in the subject matter, they could be worthwhile.

I definitely ditto the recommendation for London Walks. I also did their guided visit to the British Museum a couple of years ago - it was a Friday evening in early January - and the guide did a good job in navigating us around crowds and showing us some off the beaten path objects along with the main highlights.

I have done a tour at the National Portrait Gallery before they open - it was a nice, intimate way to see paintings up close and personal before the museum opened and while the first visitors were arriving shortly after they opened. I did that tour on a Saturday morning.
