Description

This is the full length of the legally ride-able Tolt Pipeline. From Horizon View Park to the Tolt River bridge (gated).

This trail begins at Horizon View Park in Montlake Terrace North of Seattle and ends at the Tolt River bridge East of Duvall. It's a combination of doubletrack access roads, singletrack, paved trail and paved/dirt roads connecting the main sections.

The most popular section of this trail begins at what is known as Heart Attack Hill, by Redhook brewery coming off of the Sammamish River paved trail, and ends before the very steep descent down to Sammamish Valley (approximately 7 miles).

The surroundings are made up of residential, semi-wooded, valley and wooded sections.
