The smallest ones are just big enough to fit 2 people into.
This question is very ambiguous since it depends on the model, make and type of helicopter. For instance, it depends on whether you're asking about a small, private helicopter with a bubble canopy up front, or a big military Chinook helicopter.
The helicopter was designed for situations where aircraft were needed which could takeoff and land in a very small space.
The small rotor on the tail is to counter-act the torque of the big rotor on top. So it is used for steering and to keep the helicopter stable.
It mainly allows people to land in very small places.

Most of the tours in big cities that offer visiting big structures such as bridges and vast environments such as canyons could potentially have an option of helicopter tours. They are usually very expensive.
