Hike the Pacific Northwest Trail for 1.5 miles and then left on the Samish Bay Connection Trail. In a half mile, stay right and then a half mile later turn left and continue on to Oyster Dome. It's 6.5 miles round trip with 1,900 feet of elevation gain to a high point of 2,025 ft.

Loop Return Option: Consider looping back past Lily Lake and the Samish Overlook on the Pacific Northwest trail. This adds about 2 miles to your trip.

Extend Your Trip: Consider continuing on to North Butte, a much less visited and crowded viewpoint, about a mile from the Oyster Dome-Samish Connector Trail junction. Hiking this as a loop is 10 miles with 2,500 feet of elevation gain and a high point of 2,220 ft.
