Rocky Brook Falls4.8(1,201)

Rocky Brook Falls

Tourist attraction · Brinnon, Washington

A stunning 200-foot horsetail waterfall cascading from a hanging valley on Washington's Olympic Peninsula near Hood Canal. The walk to the falls is remarkably easy — just 0.1-0.25 miles roundtrip along a flat trail following Rocky Brook Creek, making it accessible for families with young children. A swimming hole at the base is popular on warm summer days. Free parking, no passes required. The waterfall flow is strongest during heavy rain and spring snowmelt.

About this map

Every pin is a live reading from a USGS real-time monitoring station, captured in a daily snapshot. Colours follow the site’s cold-water-safety thresholds and describe the water at that one sensor — usually a river or stream gauge, not a swim beach — so treat them as a guide to what the water is doing nearby, not a verdict on a specific spot. Readings are provisional and can be revised by the USGS. Your location only sorts this page: the coordinates appear in the address bar (rounded to about a mile) and are not saved to an account or our database.

Conditions are for general information only and can change quickly. Always judge the water in person and follow posted advisories and local guidance before swimming or paddling.
