I walk with a heavy foot in snake country, most of them want to get out of your way and move on. The Puff Adder you have to almost stand on to get bitten, the Mamba and Cobra will stand their ground at least and attack at worst.
My advise give them plenty of room, learn what they look like and where they live, constantly visually sweep the path in front of you and train your eye to spot any type of movement.
Remember not all of them live on the ground some of them live in trees. I've seen some wonderful Boomslang, Boa, and even Black Mambas cruising the branches. Water snakes, sea snakes, etc.
Handling and moving snakes with a stick is a sure way to get bitten unless you really know what you are doing. Move around them don't move them around you.
