St. Paul's shows up as a landmark on almost every one of these tours rather than the main event, so you're picking a London walking or driving tour that passes the cathedral. The good news is the variety is excellent and mostly cheap: a $25 medieval history walk, a $26 all-city sightseeing march, a $26 Harry Potter walk, and a $40 historical-pubs crawl all rate 4.9 or 5.0. The outliers are two private black cabs north of $430.
Pick by theme. If you want the cathedral in the context of medieval London, the Tower-based history walk is purpose-built. If you want breadth, the 30-sights walking tour is the workhorse. Harry Potter fans and pub-lovers each have a dedicated, well-reviewed option. Only reach for the black cabs if walking is off the table and budget isn't a concern.

★★★★★ 5.0 (332 reviews)·from $442·4h 00m·Private

★★★★★“Expert historian Mik took us a this Medieval tour of London, which should be renamed to the Medieval Fire tour of London based off how much all the great fires reshaped the city. He did a great job making this interesting for all and answering our many questions. Our family agrees he has excellent photography skills as well.”

At $430.39 this private black cab tour backs its 4.9 rating with 1,868 reviews, the largest sample of any tour in this hub by a wide margin.

#5Best for Pub Lovers
London Small Group Tour of Historical Pubs
A historical pub crawl with a huge, happy following.
★★★★½ 4.9 (1,608 reviews)·from $40·3h 30m·Small group
At $40.26 this small-group tour of historical pubs pairs St. Paul's, Blackfriars Bridge and Fleet Street with actual pints, and its 4.9 rating over 1,608 reviews is the deepest track record in this hub.

★★★★★“Very nice trip through London while visiting some realy cool pubs. Chris is an experienced guide, and that expertise comes through nicely. He offered up some great information as we wandered to four different pubs. Timing was relaxed and we had time to sip a full or half pint at each stop. Chris also made sure he spent time with each member in our group so no one felt left out.”

High-Speed Thames River Speedboat in London
A quick Thames speedboat thrill, light on the cathedral.
★★★★½ 4.9 (613 reviews)·from $97·0h 50m·
For $97.12 this 50-minute high-speed speedboat rockets past the London Eye, Big Ben and Parliament from the water, rated 4.9 over 613 reviews. It's the fun outlier in a hub full of walks, best as a between-tours adrenaline hit. Just know St. Paul's isn't really the point here.
★★★★★“It was AWESOME! I went with my 11 yr old son & it was such an adrenaline rush! We both agreed it was the highlight of our trip! The guide Sofia and Skipper Jon were both brilliant. We literally felt like we were in a James Bond chase on the Thames! It also helped that it was a gloriously sunny evening so weather conditions were perfect.”

Before you go: 7 things worth knowing
- Book ahead in peak season. The best St. Paul's Cathedral tours in England sell out days in advance — especially skip-the-line, small-group and special-access ones.
- Arrive 10–15 minutes early. Operators start on time and latecomers can lose their slot; major sights also have airport-style security.
- Check the meeting point the night before. Several tours don't start at the main entrance — some meet at a nearby office or square. Screenshot the location.
- Bring photo ID. It's required for many timed-entry tickets and special-access areas.
- Wear comfortable shoes. Most of these involve a lot of walking on uneven ground over a couple of hours.
- Look for free cancellation. Many tours let you cancel up to 24 hours before — handy if plans shift. Check the terms before you pay.
- A guide is usually worth it. The sights are impressive on their own, but the stories and context are what people remember.
How I ranked these
I weighted three things: what you actually get for the money (group size, what's included, special access), the rating balanced against how many reviews back it up — a 4.9 from 200 people isn't the same as a 4.6 from 15,000 — and price for what's on offer. Ratings, review counts and prices are pulled from Viator and shift over time, so always check the live booking page before you pay.
Good to know
Are skip-the-line tours worth it?
At major sights in peak season, yes — standard queues can run 1–2 hours and timed tickets sell out. Every tour here includes entry.
Can I cancel?
Many tours offer free cancellation up to 24 hours before — check the terms on each booking page before you pay.
How far ahead should I book?
1–2 weeks for standard tours; 3–4 weeks for special-access or small-group options, which sell out first.
Are these prices final?
They're "from" prices and change with date, group size and availability. The live price shows on the booking page.
