I have created a box around my player and am using your playground model which works great however my character just slides all over the map and I have no control. Anyway way to like make it so they can walk around and not be stoped by hills etc

If you're using the SimpleCharacterController or CharacterController, you can increase its MaxSlope field. If you're not, you can take a look at those two classes (in the BEPUphysicsDemos source) to see how they work.
