Understanding the Underground Environment

The tunnels beneath Prague are remnants of the medieval city. These spaces are often damp and humid. The temperature usually stays between 10°C and 15°C (50°F to 59°F). This remains constant even during a hot Czech summer. You will encounter narrow passages and low ceilings in many areas.

The ground consists of original 12th-century stones and dirt paths. These surfaces are rarely level. Water often seeps through the limestone, creating small puddles or slippery patches. You should expect dusty environments in less-restored sections. Understanding these conditions helps you choose the right gear.

Many tours visit former dungeons or cellar systems. These areas were once the street level of the city. Over centuries, the city level was raised to prevent flooding. Today, these historic rooms sit several meters below the current pavement. You can learn more about these sites via the Prague official tourism portal for current access details.

The Best Footwear for Subterranean Exploration

Footwear is the most important part of your outfit. The medieval floors are uneven and can be very slick. You will likely walk on a mix of cobblestones, gravel, and metal grates. High heels are dangerous and should never be worn on these tours. They can easily get stuck between stones.

Choose shoes with a thick rubber sole for better cushioning. Hiking shoes or high-quality sneakers are ideal choices. If you plan to visit the Old Town Hall underground, expect many steps. Flip-flops provide no support and offer zero protection against stubbing your toes. Sandals are also discouraged due to the dust and occasional dampness.

Make sure your shoes are broken in before your trip. A long walking tour is not the time to wear brand-new boots. Blisters can quickly ruin your experience in the narrow tunnels. If your shoes have laces, double-knot them to prevent tripping in low-light areas.

Seasonal Decision Guide for Travelers

Your clothing strategy changes depending on the month of your visit. Use this guide to adjust your layers based on the outdoor weather in Prague.

• If it is Summer (June–August): Carry a light hoodie in your bag. The 15-degree temperature drop can feel shocking when it is 30°C outside.
• If it is Winter (December–February): Wear layers you can easily unzip. The underground is often warmer than the freezing streets, so you may get too hot in a heavy parka.
• If it is Rainy: Ensure your shoes have extra grip. Wet shoes from the street will be even more slippery on the smooth underground stones.

Troubleshooting Common Underground Issues

Even with the right clothes, you might face some challenges. Being aware of these issues helps you stay calm and safe. Most guides are very experienced and will help you navigate the tricky parts.

• Slippery Surfaces: Walk slowly and use handrails whenever they are provided.
• Low Light: Allow your eyes a few minutes to adjust to the dim environment.
• Claustrophobia: If spaces feel too tight, stay near the back of the group where there is more air.
• Low Ceilings: Watch your head constantly, especially if you are over six feet tall.
• Dust and Allergies: Wear a mask if you are highly sensitive to old dust or mold.
• Camera Safety: Use a wrist strap so you do not drop your phone into deep crevices.
• Stair Fatigue: Take your time on the spiral staircases to avoid dizziness.

If you find the underground too intense, consider exploring hidden gems in Prague Old Town above ground. There are many historic sites that do not require going into deep cellars. Always listen to the safety briefing at the start of your tour.
