O'Neil Pass

Olympic Peninsula

updated 1 month ago

We have limited recent trip reports for O'Neil Pass from July and August 2026. The trail is described as having minor obstacles and being snow-free as of August 24. However, other reports indicate sections can be overgrown and brushy, with trees down across the trail, July 31, and July 9. The road is generally suitable for all vehicles, though one report from July 31 notes it as rough but passable. Bugs are not a significant issue according to the available reports. Hikers should be prepared for potential annoyances from brush and blowdowns.
