Attacks are always possible, however, as is injury from any wild animal. Watch children closely. Never let them run ahead or lag behind on the trail. Avoid hiking or walking alone. Do not leave pets or pet food outside and unattended, especially at night.
Pets can attract mountain lions into developed areas.
Store food per park regulations. Never approach a lion, especially one that is feeding or with kittens. Most lions will try to avoid a confrontation, so always give them a way to escape. Hold your ground or back away slowly. Face the lion and stand upright.
