The Tolt Pipeline Trail runs from Woodinville, Washington, to Duvall, Washington, where it connects (via a short bike lane) to the 29-mile Snoqualamie Valley Trail. The Snoqualamie Valley Trail continues to North Bend, where it connects to the Iron Horse Trail. The Woodinville end of the trail also connects to the Sammamish River Trail.
Note that the Tolt Pipeline Trail is only suitable for a mountain bike, and is quite steep. The Snoqualmie Valley Trail is much flatter and should be suitable for most bicycles. The orange icon on the map is near the start of the Snoqualmie Valley Trail.

Nice easy unpaved rail trail. I live 3/4 mile from it and ride it regularly.
You can hook up to the upper portion at Snoqualmie Falls (If you know the route) and ride all the way to Rattlesnake lake and hook up to the Iron Hose/John Wayne trail if you research ahead of time.
Map is not accurate. North end of trail is Duvall. South end is at Tokul Rd tunnel. You need to take to pavement to hook back up to the trail at Snoqualmie due to private property. Go to google maps to figure it out.
Just to clarify, my map above is a combination of the Tolt Pipeline trail (Woodinville to Duvall) and the Snoqualamie Valley Trail (Duvall to North Bend), as mentioned in the text…

is the tolt pipeline trail for road bikes (paved) or is it a gravel based trail?
Check the comments above, and the bottom of the main description — it is not paved.

Where is the steepest portion of the trail located? Is it right off the Sammamish River Trail?
Tried the Tolt Pipeline one time from the Sammamish River Trail. Rode about 30 feet up that darn steep unpaved dirt “mountain” and had to walk the rest of the way up. Got to the top and it looked like a lot of elevation loss to continue towards Duval. Turned around and never tried it again. P.S. There are paved roads in the area you could use to ride to the top!
Around where does the Tolt Pipeline connect to the Sammamish river trail? Are there signs in the area? Thanks!
The connection is in Duvall. Check the link in the text above for more information on the Snoqualmie Valley Trail — I think that site has a map.
I should probably remove the Tolt Pipeline trail from this listing… it’s really only suitable for mountain bikes.

Rode the Snoqualmie Valley Trail down from Cedar Falls this last Saturday. What a gem of a trail! Even with light rain early in the ride, It was enjoyable. Unfortunately, I neglected to take a blow up of the map with me and wound up on 396 WY SE and then Tokul Road. Quite a hill climb involved there. Rode down through the old mill and back out. Finally wound up at Snoqualmie Falls without finding the hook up towards Duval. So turned around and rode back to Cedar Falls for total of 29 miles. Then did another 22 up to Alice Creek and back on the JWT Will be back to start from the Duval end before cold weather sets in I’m sure.
