Before you go
The map shows where falls are, not whether they are open or safe to reach. Check the land manager, usually a state park or national forest, for closures, fees and permits, and stay on the trail near the water. Our waterfall safety guide covers the hazards, and waterfall hikes near me explains how to pick a trail.
