Typical trail obstacles
Obstacles are trail features or conditions that impede or make hiking progress difficult or unpleasant. What is an obstacle depends on personal abilities and adaptive equipment being used. What is an obstacle for me may not be an obstacle for you. Listed below are typical obstacles found in trails. Some obstacles are temporary, such as fallen limbs. You probably have your favorite set of obstacles.
