London is one of those cities where even a short walk turns into an adventure, one minute you’re passing Big Ben, the next you’re sipping tea in a hidden courtyard or stumbling upon a market stall with gluten-free Ethiopian injera. It’s layered, lively, and full of surprises.
While we came to London looking for safe gluten-free eats for our family (both my husband and son have celiac disease), what really made the trip magical were London’s experiences, the ones that let us explore London’s past, see it from new angles, or just step off the tourist trail for something unexpected.
If you’re planning your own trip and want to go beyond the usual photo ops, here are some of the most memorable London experiences and activities you can book, each one offering a different perspective on the city.
1. Hidden London Walking Tour
Book the Hidden London Walking Tour
Let’s start with a favorite. This walking tour took us through quiet alleyways, Roman ruins, and tucked-away corners that aren’t in the guidebooks. It felt like time-traveling through layers of the city, from medieval markets to WWII-era bunkers.
Our guide was a storyteller in the best sense, mixing fascinating history with personal anecdotes, all while walking through passages I never would’ve found on my own. Highly recommended for history lovers and curious wanderers alike.
Time needed: ~2 hours
Best for: History lovers, first-time visitors who want to see a different side of London
2. Gangster Tour of London’s East End with Actor Vas Blackwood
Yes, it’s led by a real actor. Yes, you’ll hear stories that sound like movie plots. And yes, it’s just as fun as it sounds.
This tour dives into London’s East End, once home to notorious gangsters, now a hotspot of urban art, food, and culture. Vas Blackwood (from Lock, Stock and Two Smoking Barrels) shares insider stories and wild historical facts that make the streets come alive. Even if gangster lore isn’t your thing, the personality of the guide alone makes this walk unforgettable.
Time needed: ~2.5 hours
Best for: Pop culture fans, adults/teens, groups looking for something different
3. Secret Walking Tour of Central London
This one surprised us. I thought we’d seen most of central London, but this tour proved me wrong. We visited places I’d walked by a dozen times without realizing their stories, like the smallest police station in the world and a hidden water gate used by Tudor royalty.
It’s the kind of experience that gives you goosebumps, in a good way. If you’re someone who likes whispering “whoa” under your breath every five minutes, this is the tour for you.
Time needed: ~2 hours
Best for: Returning visitors, curious minds, solo travelers
4. Self-Guided GPS Treasure Hunt Tour
Want something a little more playful? This self-guided treasure hunt turns London into an interactive game. You’ll use GPS clues to navigate from one spot to another, think secret gardens, historic pubs, and quirky architecture, all while solving clues along the way.
We did this as a family and loved how flexible it was. You can pause for lunch, go at your own pace, and even split into teams if you’re traveling with friends. It’s also a great way to get kids excited about sightseeing.
Time needed: Flexible (1–4 hours)
Best for: Families, couples, groups, DIY adventurers
Day Trips from London That Are Totally Worth It
Sometimes you just need a change of scenery, and London makes it easy with day trips to some of the UK’s most iconic spots. Here are a few we’ve done and loved:
1. Windsor Castle
Windsor is regal, walkable, and packed with history. Plus, it’s a quick train ride from central London. The castle is grand and gorgeous (yes, that’s where the Queen spent her weekends), and the town itself has charming shops and riverside views.
Tip: Pack a gluten-free picnic or stop at Bill’s in town for a celiac-safe meal.
2. Oxford & Cambridge: Two Iconic University Cities in One Day
Book the Oxford & Cambridge Day Tour
If you’re torn between visiting Oxford or Cambridge… why not do both? This full-day tour from London makes it easy to explore two of England’s most prestigious university towns, each with its own distinct vibe, architecture, and academic legacy.
Time needed: Full day
Best for: History lovers, architecture fans, and anyone curious about life at the UK’s top universities.
3. Harry Potter Warner Bros. Studio Tour
Book the Harry Potter Studio Tour
Step behind the scenes of the Wizarding World on this full-day Warner Bros. Studio tour, complete with round-trip coach transport from London. You’ll explore original sets like the Great Hall and Diagon Alley, see real props and costumes, and uncover movie-making secrets, all without the stress of planning logistics.
Time needed: About 7h
Final Thoughts: See London Differently
If there’s one thing we learned during our trip, it’s that the best parts of London aren’t always the ones on postcards. They’re the quiet alleyways you explore with a local guide, the unexpected stories that stick with you, and the neighborhoods that make you feel like you’ve discovered your own little corner of the city.
If you’re planning a trip to London and want to do more than snap photos at the usual spots, these experiences will give you stories to tell, and not just souvenirs.
Planning Tips:
- Many of these tours book up fast, especially on weekends, reserve your spot early.
- For multi-day stays, consider pairing a city tour with one day trip outside London.
- If you have celiac disease or gluten intolerance, London is one of the most supportive cities we’ve visited. Read our full gluten-free dining guide here.
FAQs About Booking Experiences in London
1. Are London tours worth booking in advance?
Yes, especially walking tours, day trips, and studio experiences like the Harry Potter tour. Many of the best experiences sell out days (or even weeks) in advance, particularly during spring, summer, and holidays. Booking ahead also saves you time and stress while you’re actually in the city.
2. What’s the best tour if I’ve already visited London before?
If you’ve seen the big landmarks, try a Hidden London Walking Tour or the Secret London GPS Treasure Hunt. These take you off the beaten path and show you a completely different side of the city that even locals love rediscovering.
3. Are these tours family-friendly?
Absolutely! Most experiences are great for kids, teens, and adults alike. The Harry Potter Studio Tour is a hit with families, while self-guided options like the treasure hunt let you explore at your own pace. Just check age recommendations on each tour listing before booking.
4. Can I do a day trip from London and still be back for dinner?
Yes! Tours to Oxford, Cambridge, Windsor, and even Brighton typically return by early evening, making them perfect for travelers who want to explore beyond the city without changing hotels. All the logistics are handled, so you can just enjoy the ride.
5. Do I need to print tickets or can I use my phone?
Most Viator tours accept mobile tickets, but it’s always a good idea to double-check the confirmation email. I recommend screenshotting the ticket or confirmation just in case you have spotty Wi-Fi during your trip.
