This is PATH - the world’s largest underground pedestrian network - with over 30 kilometres of connected walkways beneath the city.
It’s connected to office towers, hotels, shopping centres, restaurants, Union Station, and even some of Toronto’s biggest attractions.
It’s very helpful if you’re visiting in the winter or on a rainy day because you can get around downtown while staying warm and dry.
The only downside? It can be a little confusing your first time, so keep an eye on the coloured signs and maps as you go.
Save this for your next visit to Toronto.
During my visit to Toronto, I found the PATH system to be an absolute game-changer, especially during the colder months. What makes PATH unique is not only its vast scale—being the world's largest underground pedestrian network—but also how seamlessly it connects you to key destinations such as office towers, shopping malls, restaurants, and iconic sites like Union Station and the CN Tower. This network spans over 30 kilometres of indoor walkways, which is perfect for those looking to avoid harsh weather conditions like rain or freezing temperatures. One thing I quickly learned was the importance of paying attention to the colored signs and maps scattered throughout the PATH. The signage is designed to help you navigate its complex maze, but it can be a bit overwhelming for first-timers. As someone who loves exploring cities on foot, having this underground alternative meant I could comfortably walk across downtown Toronto without ever stepping outside—an incredible convenience that saved me from the elements and allowed me to discover hidden shopping centres and eateries. If you're planning a trip to Toronto, especially in winter or during rainy days, I highly recommend factoring in PATH into your itinerary. Not only does it provide shelter, but it also offers a unique perspective of the city's hustle and bustle from below street level. It also connects to many of Toronto's largest banks and business hubs, adding a layer of practicality for anyone with professional engagements downtown. From my experience, while PATH might seem a bit confusing at first, it quickly becomes intuitive after your first few walks. Take some time to observe the color-coded direction signs, and consider grabbing a PATH map at visitor centres or downloading an app to help you navigate. Overall, PATH isn’t just a pedestrian network—it’s an integral part of Toronto’s urban experience and a must-try for visitors looking to explore the city comfortably and efficiently.
