Who knew Brno is the second-largest city in Czechia?? Definitely not me. Though, to be fair, I had never even heard of Brno before we started planning this trip.
While most people opt to visit Prague—we had originally planned to do the same—it’s a long trek from Vienna, and it ended up feeling like “too much.” Brno, on the other hand, is an accessible and surprisingly charming day trip within the region.
Planning a Brno day trip from Vienna? During our very full day in the city, we saw the famous astronomical clock, climbed the Cathedral of St. Peter and Paul, explored two underground attractions, and wandered around Špilberk Castle. Here’s our complete one-day Brno itinerary, along with practical tips, approximate costs, and the activity I wish we had booked in advance.
Looking for other easy day trips from Vienna? We also took a Bratislava day trip from Vienna and visited Sopron, Hungary—two more simple ways to cross into another country for the day.
How to Get from Vienna to Brno
We opted to take FlixBus because it was the cheapest option to get from Vienna to Brno for our dates. It was a straight shot and Brno was the first stop; we were dropped off less than a kilometer from the main square.
We left our apartment early, without any caffeine in our systems, so once we got off the bus, we made a stop at Costa Coffee. It was delicious and a great way to start our Brno day trip.
At least at this coffee chain, there’s a code on your receipt to access the washrooms. Overall, we found far more free bathrooms in Czechia than in Germany, Austria, or Slovakia!
One of the reasons we’d chosen the bus—in addition to the cost savings—was that it would get us into town early enough to reach the Brno Astronomical Clock well before 11 am.
What to Do in Brno in One Day
See the Brno Dragon at Old Town Hall
We took a scenic route to the clock, stopping first to see the Brno Dragon at Old Town Hall.
The “dragon” is actually a crocodile, and it points back to a famous local legend. Apparently, a dragon was terrorizing the city until someone tricked it into eating quicklime. It got thirsty, drank loads of water, and because of the chemical reaction, burst.
Medieval problem-solving at its finest.
Visit the Brno Astronomical Clock Before 11 a.m.
Okay, back to the famous Brno Astronomical Clock.
According to the local story, when Swedish forces were besieging Brno in 1645 during the Thirty Years’ War, they promised to leave if they failed to successfully capture the city by noon.
The bell ringers decided to announce noon an hour early. The Swedes retreated, and the cathedral bells still ring at 11 am instead of noon to commemorate the occasion.
There’s all sorts of physics and mechanics behind how the astronomical clock works and tells time. Of special interest to the kids, however, was the chance to catch the GIANT glass marble it releases each day at 11 am.
There are four openings at about shoulder height, and the marble randomly drops out of one of them.
From my research online, I knew getting there early was crucial. Locals often stake out a claim to the openings so they can get the marbles and, I presume, sell them to tourists like us.
Indy had his hand in one opening with a stranger, but alas, no luck. The gentleman in the white sweater behind Indy was the successful one.
This was a bit of a letdown because Belle was spoken to rudely by someone who wasn’t actively trying to get a marble but then claimed to have been there first. It put a damper on the experience for sure, but I was relieved the rude woman didn’t have the “winning” opening.
Walk Through Freedom Square
After the bust at the clock, we walked across Freedom Square to see the Marian Plague Column.
Literally every city we’ve visited so far has one of these!
Climb the Cathedral of St. Peter and Paul
From there, we made our way up to the Cathedral of St. Peter and Paul. It’s also tied to the story of the Swedish siege; the famous early bell-ringing trick came from here.
Everything was so picturesque.
Oh look, there’s a wall to climb and a hint of danger. Sign me up, says Indy.
Of course there HAD to be some archway poses in Czechia, right?!
When we went inside the cathedral, we learned there was paid access to the towers, and both kids were keen.
We try to climb a tall structure in every city.
We qualified for the family rate, which worked out to about €12 total at the time, I think? They did accept card which was good because we didn’t have any cash!
You walk through the interior of both towers to reach two different viewing platforms. Both platforms are very small, but they offer great views of the city below.
Love those red roofs with terracotta tiles.
The lighting on the other side was horrible, but a kind stranger offered to take our picture.
I love these pictures of Indy looking out the various inset windows while we were walking down the stairs!
Find Brno’s Quirky Public Art and Statues
Then… we wandered the streets for a while.
These optical-illusion cones in Dominikánské náměstí—Dominican Square—were such a cool find. They reminded me of Bugles!
They looked wide but actually had very narrow openings. They’re an art installation in the off-season, but in the summer, they’re also water features.
The distortion messes with your head a bit!
Jumping off a stone bench. Why not?
I have no idea what/who this statue is meant to represent, but we thought it looked like a Minecraft character of some sort.
The statue of Jobst of Moravia (he was born/died in Brno and was King of Germany for a while) was fun! Everything looks a bit absurd which adds to the appeal.
The kids posed underneath for scale.
Brno has a LOT of quirky public art, which made wandering around the city especially entertaining. There always seemed to be another strange statue around the corner.
Visit the Church of St. James and Brno Ossuary
I had planned to visit the Ossuary at St. James’ Church, but when we arrived, tickets were already sold out for the day.
It’s the second-largest ossuary in Europe in terms of the number of remains, with more than 50,000 people buried there. It was only rediscovered in 2001, so people were just casually walking over all those bodies for centuries!!!!
This is one Brno attraction I would book in advance.
The interior of the Church of St. James was lovely. We also made time to walk around the exterior to find the hidden statue of the Indecent Man, who is pointing his naked butt in the direction of the Cathedral of St. Peter and Paul.
Apparently, the two churches had been competing to build the highest tower. St. James won, and this was a stonecutter’s way of essentially sticking out his tongue—or, in this case, bare bum—at the other church.
Who knew medieval humour could be so funny?!
I really like light and bright church interiors like this.
After looking at all sorts of statues, we did some more wandering.
A post box!
More climbing for Indy!
And a teeny, tiny figurine mounted on a clock. It’s called Waiting Adam, and it’s the smallest statue in Brno.
Explore the Labyrinth Under the Vegetable Market
Earlier in the day—right after we learned the ossuary tickets were sold out—we made reservations for the Labyrinth Under the Vegetable Market.
In days gone by, homeowners would dig below their properties for cold storage. These cellars date back to medieval times and were used for storing food, brewing, and hiding valuables.
These days, they’ve been restored into a network of corridors you can explore.
The labyrinth was reasonably priced. It cost something like €25 for our whole family at the time, and we took a guided tour in English.
It was a lot of fun. The rooms are staged with props, and the tour is highly interactive.
Here’s Indy pretending to be bitten by a rat.
Thankfully, NO LIVE RATS WERE SPOTTED, or I might have died. I jump so high if I see A MOUSE. I have never actually seen a living rat and would love to get to the end of my life still able to say that.
Moving on…
There was lots of cool history about winemaking in the area, none of which I feel like typing out right now.
But it was informative and interesting.
There were other kids on the tour, but whenever the guide asked for volunteers, Indy was the only one willing to participate.
This was an old Czech drunk tank! They would lock people inside to sober up, and they reckoned it could fit eight grown men. In that case, they’d all have to sit back-to-back with their legs through the slats.
Our guide said his record with a school group was fitting SIXTEEN kids inside.
Candles were expensive, so much of the light in these underground cellars would have come from a stick of wood—ON FIRE!!!!—held between someone’s teeth.
I can only imagine how many faces got burned that way.
One adult tried making sparks with flint but was unsuccessful. The only other volunteer was Indy, who got it to work on his first try.
Something we’ve come across multiple times now is the concept of humiliation as a form of medieval punishment.
In this case, people would be shackled in the square with their crimes displayed on a board around their necks. Indy, apparently, had been singled out for selling stinky meat at the market.
Tsk, tsk.
Tour the 10-Z Bunker
Brno has really leaned into the underground theme.
Next, we visited the 10-Z Bunker, a Second World War air-raid shelter that was later converted into a Cold War atomic shelter. It was designed to hold up to 500 people for several days.
The bunker was self-guided but highly interactive, which the kids loved.
I had to chuckle at the sign at the entrance reassuring passersby that, in case of a nuclear attack, entry to the bunker is free.
They had crates full of gas masks to try on. You could handle almost everything, which really made the experience come alive for the kids.
A bit like my experience with the Vienna Crime Museum, I’d say this spot is a bit rough around the edges (read: displays aren’t highly polished and professional), but it’s really neat and feels authentic.
I read online that it’s also a hostel and you can spend the night!
There was also a heartbreaking but highly informative display about women imprisoned in Gulag camps.
Between the costumes, gas masks, old communications equipment, and endless underground corridors, this was one of the most memorable things we did during our one day in Brno.
Walk Around Špilberk Castle
I had considered visiting one final underground site: the Žlutý Kopec Water Tanks.
It would have required quite a bit more walking and would also have been the priciest option of the day. It’s primarily a really cool photo opportunity, but if I ever make it back to Brno it would definitely go on my list!
Instead, we wandered around Špilberk Castle.
I didn’t have any desire to pay to go inside, but the grounds were free, and the kids—as per usual—found plenty of ways to make the experience interesting.
The castle dates back to the 13th century and later became a notorious prison.
More statue poses!
Feats of strength…
Holes in a wall? Sure, I’ll climb! This kid does NOT stop moving.
Since Špilberk Castle is at the top of a hill, it also provides some great views of the Cathedral of St. Peter and Paul on the way down.
Practical Tips for a Brno Day Trip from Vienna
A few things I’d recommend based on our experience:
- Compare bus and train prices. FlixBus was the cheapest option for us, but schedules and prices will vary.
- Arrive at the astronomical clock early. Being there before 11 a.m. gives you a chance at the marble, though it certainly doesn’t guarantee one.
- Reserve popular attractions in advance. The Brno Ossuary was already sold out when we arrived, and several underground attractions have limited tour capacities.
- Wear comfortable shoes. We walked a lot, and several attractions involve hills, towers, or stairs.
- Bring food and snacks. Packing a lunch helped us keep the cost of our Brno day trip relatively low.
- Leave some flexibility in your schedule. Our return bus was an hour late, so I was glad we’d stopped at a grocery store for more supplies.
- Check current hours and ticket prices. Our trip was in 2026, and the practical details may change.
Is Brno Worth a Day Trip from Vienna?
We had packed a lunch and snacks, which we ate off and on throughout the day. The kids also had to extend their McDonald’s In Every Country streak, so they got a little something at the Golden Arches.
We eventually stopped at a grocery store for a few more supplies, which was a good thing because our return bus ended up being an hour late.
It was just after 10 p.m. by the time we got home, and we’d been up before 6 a.m., so it was a very long day.
Still, I think Brno is well worth considering as a day trip from Vienna.
The historic centre was charming and walkable, and there were so many unusual things to do in Brno—from the astronomical clock and bizarre public art to medieval cellars and a Cold War bunker.
We’d visited yet another country, and Brno ended up being one of the most pleasant surprises of our European adventure.

The interactive exhibits seem very cool!
My grandparents and aunt visited Czechoslovakia in the 70s. I know they went to Prague and also took a flight to the eastern part of the county on OK airlines, no idea if they visited Brno. Grandma’s parents were originally from eastern Slovakia, I’ve looked at the area on street view and the county side looks a lot like where they eventually moved to in eastern Ohio.
Oh, and to answer your question from a previous comment, I’d like to get a West Highland Terrier, I had one growing up and they have always been my favorite dog breed, but it’s also possible I’ll end up with a random mutt.
Aww. I hope your wish comes true. Terriers are SO adorable.
Wow, Brno looks gorgeous! And I love all the sights you visited. Gotta admire the passive aggressive sculpture. I am also getting a kick out of Indy being shamed for selling stinky meat. That photo of you and Belle is fabulous, despite the lackluster lighting!
The only Czech city I’ve visited besides Prague is Karlovy Vary. It’s a spa town, and I had a very weird massage experience there. Memorable, though! And the village itself is quite charming.
I heard of that spa town, I think.
I would LOVE to go to Prague at some point. I heard such wonderful things about it; just too much of a stretch for this trip, but gives me a perfect excuse to come back to Europe, right???
I know I’ve said this before, but it is amazing what you can pack into ONE DAY. I know that I’ve been frequently awed at the places that I go on my travels, and I’m not anywhere as exciting as Europe.
Especially in cities where there can be a treasure trove of unique things all within a stone’s throw of each other!!
So many thoughts!
1. Why have I never heard of Brno or Czechia? (took me 3 scrolls back to the top to spell it right)
2. Why can I find zero photos of those marbles on the interwebs?
3. It seems as if every city has an arched entrance gate area, multiple cathedrals and castles, ancient walkways and structures and more arches, multiple statues and public art. . . it’s all running together for me (but don’t stop posting!)
4. Did this trip happen before your train trip to Munich? You mentioned going “back home”, which I assume meant to your Vienna apartment. I must have read the posts out of order.
5. I was selfishly worried that we’d all lose touch once you began your Great Adventure but holy guacamole, you are so prolific and generous in your writing!
6. Indy must be a huge hit on all the tours —eager to try things, fun, and cute as all get-out.
7. Belle is a champion big sister and travel companion—all the fun poses, schlepping, fitting in school work, missing friends, lack of her own bedroom (I would have HATED that part at her age or any age, really).
8. You are taking great photos.
9. It was good to see John participating . . . I was beginning to wonder if the poor guy had to work all day, every day!
1. Czechia is still also called the Czech Republic; you’re likely more familiar with that title. I had never heard of Brno, either. But it’s the second biggest city (after Prague).
2. I never even tried finding a picture of the marbles. They were about the size of a golf ball!!
3. Yes, all the cities do end up looking so much alike!
4. Yes, I have posted things out of order, so this happened while we were still based in Vienna.
8. Awe. Thanks! It includes pictures from John AND Belle.
9. Alas, he has worked a lot, but thankfully was able to adventure on the weekends and in the evenings after work. He also did a few early morning hikes with Belle, including once to see the sunrise.
I’ve been to Prague, but not Brno. It looks really, really fun! Obviously the kids had a blast. I love all the interactive exhibits.
To answer your questions… we took a trip to Key West when Paul was young, and into his “pirate” phase. They have a shipwreck museum, all about pirates and treasure. That’s the only unusual museum that comes to mind. Also… you may remember (unless you’ve blocked it from your mind) that we have *whisper gently* pet rats. They’re so cute!!!
That museum sounds VERY fun. I know a certain boy in my household who would like that!
We went to Rothenburg in Germany and there was a museum of Medieval Crime. It had rooms of masks for people who were being shamed for committing crimes and other punishments similar to what you saw. Shame, shame!!
Your kids really look like they are having the TIME OF THEIR LIVES. And somehow Belle grew all the way up on this trip??
Czechia looks beautiful! A place I would never have thought to visit myself!
She is 15, Stephany.
FIFTEEN. A few more years and she will be graduating high school. It’s wild.
I would love to get to Prague one day, but Brno was a perfect day trip from Vienna and I’m so glad we got to dip our proverbial toes into the country.
