I like to use the tiny twigs on pine trees that are the thickness of a toothpick or smaller. Take only dead twigs that break off easily. Do not use similar twigs that are laying on the ground as they will likely be too moist.

If you are unsure of your fire starting abilities, bring a few cotton balls or wads of toilet paper soaked in olive oil. If you used a different type of oil, test it before going on the trip.

If possible, I use gray dead wood with no bark on it to get the fire going.

Here is a fire I started using these.
