What to Do in Brno: 20+ Most Interesting Places

If you are trying to figure out exactly what to do in Brno, you have come to the right place. While most visitors only think to see the main castle, the city actually hides an incredible world of subterranean secrets and world-class coffee. We have compiled over 20 of the absolute best sights to help you build the perfect Brno itinerary.

💀 Group 1: The Subterranean Labyrinth (For Dark History Fans)

Brno has some of the most spectacular underground tourist spaces in Europe. If you like mysterious locations and unusual history, start here.

• The Žlutý kopec Water Tanks: Hidden under a grassy park are three massive, historic brick water reservoirs that look like underground cathedrals. The lighting and echoes are breathtaking. You can buy entry vouchers on the official Vodojemy Brno Tickets portal.
• The 10-Z Bunker: This is a real nuclear fallout shelter built during World War II and completed by the Communist government in 1959. It was built to protect 500 important people. Today, you can walk through 500 meters of tunnels with a map. You can book a self-guided tour directly on the 10-Z Bunker Official Site.
• The St. James Ossuary: This is the second-largest ossuary in all of Europe (right after Paris), holding the remains of over 50,000 people from the 17th century. The atmosphere is deeply moving, accompanied by music written specifically for this space. You can read the history and find visitor hours on the official Go To Brno Ossuary Guide.
• Labyrinth Under the Vegetable Market: Located directly beneath one of Brno’s oldest squares, this historic network of medieval cellars and corridors sits up to 8 meters below the bustling market. It is fully covered by the municipal underground network, and you can view schedules on the official Brno Underground Labyrinth Page.

🏡 Group 2: Alternative Architecture & Quirky Walks

Most travel sites tell you to see Villa Tugendhat, but tickets sell out three to four months in advance. Here are the smart local workarounds and city center secrets.

• The Three-Villa Walk (Černá Pole): Beautiful public gardens that connect the Löw-Beer Villa, the newly renovated Arnold Villa, and the outside of Tugendhat. It is a fantastic free walk. You can book an individual tour of the stunning Arnold gardens and exhibits via the Brno iD Arnold Villa Page.
• The Legend of the Crooked Portal: Walk to the Old Town Hall (Stará radnice). Look up at the stone Gothic turrets above the entrance. The middle pillar is completely bent! Legend says the architect was angry because the city council did not pay him enough money, so he twisted the stone on purpose before leaving.
• The Brno Crocodile (Dragon): Inside the ceiling of that same Old Town Hall gateway hangs a massive, stuffed crocodile. Locals call it the “Brno Dragon” and it is the official mascot of the city.
• The Astronomical Clock: Located on the main square (Náměstí Svobody), this black stone monument drops a free glass marble every single day at 11:00 AM. Locals gather around it to try and catch the marble.

Brno is surrounded by vast green hills and forests that are fully accessible by public transport.

• Obora Holedná (The Deer Reserve): It is a massive forested park right inside the city borders where wild fallow deer walk completely free among human visitors.

You can buy your boat tickets online directly on the Brno iD Boat Ticket Platform.

☕ Group 4: Legendary Coffee, Drinks & Food

Brno has a massive university population, which has created a food and cocktail scene that is widely considered more experimental and exciting than Prague’s.

• The bar that doesn’t exist (Address: Dvořákova 1): A legendary cocktail bar known for its towering wall of bottles, professional bartenders, and custom drinks tailored to your taste buds.
• Super Panda Circus:(Address: Šilingrovo nám. 3) A surreal, hidden bar behind a plain curtain. There are no menus; instead, you play an interactive game with the staff to choose your flavor profile.
• Výčep Na Stojáka (Address: Běhounská 16): A local tradition. This pub serves excellent microbrew beers, but there are no chairs. Everyone stands on the cobblestones of the square outside, drinking beer and chatting in the open air during warm evenings.

🪨 Group 5: The Moravian Karst (The Ultimate Bad Weather Escape)

Caught in bad weather? Head 30 minutes north of Brno to the Moravian Karst. This region hides over 1,100 caves, with 5 world-class systems open to the public via the official Cave Administration. Because you are deep underground, the rain doesn’t matter!

• Punkva Caves: The crown jewel. Tour massive stalactite halls to the bottom of the 138-meter-deep Macocha Abyss, then take an electric boat cruise along a subterranean river.
  • ⚠️ Warning: Extremely popular. Tickets sell out weeks in advance; book early on the official Punkva Booking Site.
• Catherine Cave: The perfect alternative if Punkva is full. It features the “Main Dome”—a space so massive it hosts live music concerts. Famous for its unique, needle-shaped stalagmites.
• Balcarka Cave: Home to the most intricate and colorful natural dripstone decorations in the region. This multi-level labyrinth was once a campsite for Paleolithic hunters.
• Sloup-Šošůvka Caves: A massive, fantasy-like system featuring colossal dark corridors, huge vertical chasms, and dramatic underground bridges.

🧥 Quick Cave Survival Tips

1. Bring a Jacket (Even in Summer): No matter how hot it is outside, the temperature inside the caves remains a constant 7°C to 8°C (45°F to 46°F) year-round. If you go in shorts and a T-shirt, you will be freezing within ten minutes!
2. Wear Real Shoes: The paved pathways inside the caves can get damp and slick from the natural humidity. Ditch the flip-flops and wear sturdy sneakers or hiking boots.
3. The Transit Connection: You can easily reach the central hub of the caves (Skalní mlýn) by taking a direct local train from Brno Main Station to Blansko, and then hopping onto the connected regional feeder bus.

If you want to experience the postcard-perfect history of Brno and the surrounding South Moravia region, these classic historical landmarks are absolute must-visits.
