Oyster Dome is located in the Blanchard Forest, on Chuckanut Mountain. Due to its amazing views, it's one of the most popular hiking destinations in the Seattle area. Since the state got this land in 1925, the Blanchard Forest has been one of the most significant recreational parks in the area. The best time to do this hike is from May through August when chances for clear skies are higher.
The Oyster Dome Trail is 6.5-mile (10.5 km) long with 1,900 feet (580 m) elevation gain and is rated as moderate. Oyster Dome can be accessed from the Samish Overlook parking area on Blanchard Mountain. From the trail head, hikers can walk a section of the Pacific Northwest Trail, pass Blanchard Mountain, then switch to a trail to Lily and Lizard Lakes, but then turn left at the fork to catch the trail to Oyster Dome. Once on top, you'll see the Skagit River flats, Lummi Island, and Orcas Island. If the weather is clear, you will see much of the Pacific Northwest right before your eyes.
