Features: River/Creek — Views
This trail begins at Horizon View Park in Mountlake Terrace just north of Seattle proper, and ends at the Tolt River bridge east of Duvall. The trail is a combination of doubletrack access roads, singletrack, paved trail and paved/dirt roads.
The most popular section of this trail begins at what is known as Heart Attack Hill, just by Redhook Brewery coming off of the Sammamish River paved trail, and ends just before the very steep descent to Sammamish Valley (approximately 7 miles).
Flora & Fauna
The surroundings are residential, semi-wooded valley and some densely-wooded sections.
