The pressure that can be found on the surface of Venus is said to be at 90 atmospheres. If this would be compared to anything on earth, it will be similar to the pressure that is experienced when you are about 1km away from the surface of the ocean.
There are so many layers of clouds that make the surface of the planet not visible from afar. Do take note that the clouds are known as sulfuric clouds. These are different from the type of clouds that can be seen here on earth. The pressure is so high on venus because it has a dense atmosphere.
