Couloir

A couloir is like a narrow hallway but instead of being in a house, it's on a mountain. It's a special kind of hallway because it's very steep and slippery, so it's not easy to walk through. A lot of people who like to do outdoor activities, like skiing or climbing, like to try and go through couloirs. They think it's fun because it's a challenge and they get to enjoy some beautiful views of the mountain. However, it's also important to be very careful when going through a couloir because it can be dangerous if you slip or fall. So, it's important to have the right equipment and to be with someone who knows what they're doing.
