Obstruction Point Road Professional Review and Guide
"With its wildflowers and views of the Olympic Mountains, particularly glacier-capped 7,965-foot Mt. Olympus and the park’s deep river valleys, this short, narrow and winding ridgeline road packs a powerful scenic punch as it climbs to 6,150 feet. It runs both just below and on top of Hurricane Ridge (named for the winds that blow in winter), and ends above tree line at the base of 6,450-foot Obstruction Peak.
The parking area at the end of the road is the trailhead for a number of day hikes, including the steep, 7.6-mile (one way) Grand Ridge Trail to Deer Park. On a good high-clearance, native-surface road. The park tries to have the road open by July 4, depending on weather and the previous winter’s snowpack. It is generally closed to overnight parking in early October. It is closed altogether by the end of October. It is also closed whenever snow, which can occur anytime, makes driving hazardous."
