Plan for the terrain
Water levels can change quickly after rain, including rain upstream. Do not enter fast-moving water or rely on a waterfall-flow estimate to judge a crossing.
The listed 5-mile length does not account for detours, rests or the time needed to return. Access has not been verified; confirm the current status with the land manager.
Check before you leave
- Read the latest National Weather Service forecast and alerts for the trail area.
- Confirm the manager’s current access and permit rules, including the intended entry point.
- Share your route and expected return time with someone, and choose a lower-exposure alternative if conditions change.
