Here is the list of possible options if you run out of toilet paper on the trail, tried and tested by many before you:

Leaves.
Oval rocks and pebbles.
Rounded sticks.
Moss.
Pine cones.
Water.
A handful of grass.
Sand.
Obviously, you will use what you have at hand, this will depend on the surrounding.

The order in the list above is my order of preference.
