You can help protect our treasured National Park Service (NPS) sites.


If you see something suspicious in any NPS location, or if you have information that could aid an investigation, stay safe and tell us about it. We understand that it may take time to reach park personnel and/or areas with cell or internet service. Talk to any NPS employee for help in reporting suspicious activity, or submit a tip for any NPS site anytime. We received roughly 3,000 tips in 2020 concerning incidents across the National Park System, including some for public lands administered by partner agencies.

You don't have to tell us who you are, but please tell us what you know:
