Kulshan Creek Trail

Combine with Skagit River Walk

September, 2020 by aliciashankland_tl

This trail begins with a few confusing blocks through an industrial part of city, but then becomes its own path through a largely shady stretch that is very pleasant. On the river, you can connect with the river walk. For a mile of so of s broad boardwalk, there are nice river views, parks, playgrounds, art, casual restaurants. The trail becomes rough gravel after passing warehouses.

Cascade Trail

like a country road

Amazing, peaceful and lovely flat trail with lots of shade.

Whitehorse Trail

Whitehorse Trail: Trafton to Darrington

August, 2020 by jonannis86

Whitehorse Trail is essentially open now, but access from the popular Centennial Trail to the rail bridge west of Trafton Trailhead remains closed due to unstable soil. This isolates an otherwise hidden gem of a trail. This means that you can have 23 miles of scenic, gentle rail trail all to yourself, with the possible exception of a few fellow travelers “in the know” and local swimmers and fishers. The trail runs parallel to Oso Slide Memorial Hwy (State Rte 530) and the north fork of the Stillaguamish River. The repurposed former BNSF rail route, disused after 1990, offers solitude just off the highway, lush forest vegetation and an inviting river, a refuge from dappled sun and light rain. There are openings to spectacular views of the river and encircling mountains, abandoned mills, rustic farms and homesteads, and sometimes flashes of wildlife, and beach life. There are several planked or concrete bridges, long straightaways and shallow curves, and two, busy, no-signal highway crossings, but otherwise few notable road crossings. The trail is wide and smooth, freshly resurfaced with fine, coarse gravel suitable for road bikes in the western- and mid-sections. It’s even paved in two places, near lively Twin Bridges and serene Cicero Pond, and fronting the somber Oso Landslide Memorial site. East of the Swede Heaven Rd crossing toward Darrington, the trail narrows and is swallowed up by thick forest and dense bogs. It gets much bumpier or more muddy in season, suitable for mountain bikes. There is an easily passable (though not officially) slide area east of the rodeo and bluegrass music arenas. Nearby is a mountain bike “skills area”. Parking is offered in the mid-section of the trail north of the highway at a paved lot on Fortson Mill Rd, a dirt lot immediately off C-Post Rd, and an extensive pullout at Hazel Hole. Trailheads at Trafton (Kroeze Rd/115th, at Cloverdale Farm) on the west end and Darrington (Price St, past the IGA) to the east offer space for about a half-dozen vehicles each. There are many unnamed pullouts along the highway. Per Snohomish County rules, the multi-use trail is open to bicyclists including class 2 ebikes, hikers and horses only (no motorized vehicles). Hours are 7 am to dusk, pets must be on-leash, no fires, dumping or alcohol, and the trail doesn’t offer latrines, water, or other services at this time

Olympic Discovery Trail East - Port Townsend

Beautiful and Fun

August, 2020 by t.sq

We rode this beautiful and fun ride and enjoyed water views (the first mile) and beautiful, shaded forests the remainder 6 miles. The trail was well marked in all but one area (about 6 miles in from Port Townsend) where you ride a gravelly rural road for a very short distance. One small section through the forest is almost like single track: fun!

Cascade Trail

Wondeful ride up and down Cascade Trail

July, 2020 by georgesaul

Saturday, July 25, 2020 72 degrees, sunny. Gorgeous views with foothills in near background. Skagit River was beautiful and very close-by the first half of trip going up. Gravel trails were in good shape. Some to be expected potholes. Only one 1/2 mile easy detour. In 5 hours in the trail we saw only 15-ish other people. Where are they on such a gorgeous day? Everyone we encountered was very pleasant. Highly recommend for round trip or 1-way!

Snohomish County Centennial Trail

Centennial Trail North to South

July, 2020 by georgesaul

Gorgeous day. 75, partly sunny, not very crowded. Countryside 75% of ride was extremely pleasant and pretty. There was a 1 mile detour as was noted on the official website. A busy, narrow road was the only bypass we could find. This Snohomish trail should serve to inspire other communities. Well done! The Trail Link web site should have links to the local official website(s). If it already does, I should have looked harder.

Tommy Thompson Trail

Tire hazard while crossing Fidalgo Bay

April, 2020 by hpywndrr

The seagulls keep busy dropping clams on the hard surfaces of the TTT, mainly out where it crosses the bay. There is a sign now by the RV park warning of the hazard. After maybe 10 crossings it appears the trail gets swept of broken shells now & then (thanks city?), but they are soon back. That said, I can usually maneuver around them.

Interurban Trail (Bellingham)

Great ride with the autumn colours

October, 2019 by mikedunn377842

Late October 2019 Started in Bellingham on the South Bay trail to Fairhaven which connects easily to the Interurban Trail, about 9 miles total each way... very nice ride with fantastic views of Bellingham Bay and some of the San Jaun islands. Most of the trail is flat and well packed but you do have to descend into and climb out of a couple of gorges where there were once rail bridges now long gone. Historic Fairhaven is a beautiful spot for lunch, lots of options. Will definitely do this one again!

Whitehorse Trail

Darrington to Fortson Mill

July, 2019 by volkeno

Nice trail a little bumpy in places and overgrown with grass. The Darrington end starts by the airport and is near the IGA. The trail runs behind the Bluegrass festival grounds which gives great views of Whitehorse mountain. There is a wash out in one section near the river. It’s ok for bikes to ride by, or walk past. The trail is in the woods or in people’s back yards to Fortson Mill. The old mill is off in the woods and there is a parking lot. I went another mile west until there was a bridge marked closed. I had previously tried from the Centennial end, but the landslide still was blocking the trail. Hopefully more will open soon.

Whitehorse Trail

TRAILBEAR TOURS THE WHITEHORSE … “OMG, blacktop!”

March, 2019 by trailbear

Late Summer 2018

TrailBear was not exactly “silent, upon a peak in Darien” when he parked at the twin bridges site (Rt. 530 & RR bridges) on the Whitehorse Trail (48°15'58.29"N x 122° 0'44.53"W).

“OMG, blacktop!” A few yards over, the trail surface was gleaming blacktop. Blacktop! Bear loves blacktop on his trails. Smooth riding. No ruts. Yes! We can do this! The trike came out and TB went spinning over the bridge and down the newly surfaced trail bed.

Smooth, fresh blacktop and dried leaves crunching under the tires. Looking closer, he wondered if he was one of the first riders on this stretch. There were only three tire tracks behind him. All evenly spaced. Might be him.

Was there some association with the construction crew he passed a few miles east where the trail crosses Rt 530 again… They were laying down more blacktop, heading east towards Darrington. Got a ways to go. Encourage them. They expected to be done with the trail project back in 2016. Perhaps 2020 might be the year. A bear can dream.

Regardless, the twin bridges is a lovely spot on the trail. You have a nice railroad bridge, a river with a long view, a beach for the kids and views. Locals are found recreating themselves here all summer.

Go west down the blacktop a bit and there is the Rt. 530 trail crossing – under construction. Wonder how they will do this. The Snohomish Centennial has a ped-controlled stop light at one crossing. This crossing is on a curve to make it sporting.

He managed to pedal across – but he waited and waited for a lull. Those fully loaded logging trucks doing 60 mph suggested caution. No sign of paving continuing west towards Trafton Trailhead. Back in 2016 when he checked out the Trafton Trailhead, he noticed they had laid a serious compacted gravel base heading east from Trafton, so there might be hope that was going to be a blacktop base.

@@@ MAP CHECK … The Whitehorse Trail project map – check it out

Here is the county project map. Currently, it is the best that you can easily put your hands on.

https://www.snohomishcountywa.gov/3693/Whitehorse-Regional-Trail

TB really hopes that the map note with a date of 2106 was a typo. You can see that they are doing this and that here and there. They have Phases. Must be a challenge to find all the funding for all the projects that add up to a completed trail.

The finished trail, combined with the excellent Snohomish Centennial Trail that runs from the Snohomish River north through Arlington to the Skagit County border will make this an even more attractive destination for riders.

The old right of way extends north along Rt. 9 in Skagit County and south into King County where it is the Burke-Gilman Trail. There are said to be plans to join the Snohomish to the B-G. Come that day, you can start at the Golden Gardens on Puget Sound and ride up to the Skagit line or cut over to Darrington.

@@@ FORTSON MILL TRAILHEAD … Welcome Wagon not in evidence (48°16'25.43"N 121°43'53.57"W)

TrailBear had such high hopes that morning. He would park at the Fortson Mill Trailhead and take a round trip east to Darrington and back. After all, the official map said this was the only open portion.

His hopes faded when he drove in … to the gate, hefty and well-locked. An official and rather annoyed sign proclaimed that “This Gate is Locked due to illegal dumping.” (Guys, if you are going to do caps, do caps for every word. More stylish.) Among the prohibited items were Alcoholic Beverages and Motor Vehicles. Not the place to party on a Friday night. At least the county hopes so. The gate says so.

Reading that ‘Foot traffic is allowed into the park” he hoofed it down the road to find a vast, empty parking lot in the woods. Great place to dump that old washer or have a kegger on Friday night. No signage.

More wandering about turned up the Fortson mill – now concrete walls with artistic graffiti, a dam and empty log pond and not much more. The trail is due north about 93 yards from the non-parking lot, over the slope and down.

@@@ DARRINGTON TRAIL HEAD … End of the trail (48°15'32.10"N 121°36'16.33"W)

Well, try the official open portion from the other end. Off to Darrington and the trail end on Railroad Ave. Pedal off down the trail and past the Three Rivers Mill. The trail here is gravel, and TrailBear was soon bored. Scrubby, cut over woods, no views, bumping over roots. Boring!

Stop, about face, pedal back. The reality is that from Fortson to Darrington, the Whitehorse is a woods ride. No bridges, no river, no views. TB has ridden the Trail of the Coeur d’Alenes and other scenic trails, so he is spoiled rotten and feels Entitled.

He wants scenic trails with endless unfolding vistas – an endless Instagram Heaven – not a bunch of scrubby woods. (And, while you’re at it – a rest room every five miles.)

He loaded up and headed back west to his happy discovery of real, fresh blacktop, a bridge and vistas at the twin bridges: “OMG, blacktop!” One happy TrailBear.

Snohomish County Centennial Trail

Beautiful Trail - not enough time

September, 2018 by gouldie64

This is a beautiful trail. I had a free afternoon on a business trip to Seattle. Terrible traffic to get out of Seattle, but worth it to add this trail to my list. I wish I’d had more time. Had to cut my mileage short because I kept stopping for photos.

Guemes Channel Trail

Guemes Channel Trail

June, 2018 by javajudy

This is a lovely paved trail that hugs the shoreline along Guemes Channel where large ferries regularly ply the waters between Anacortes and the San Juan Islands. The views are outstanding and the trail is accessible year round. Make a right turn off Highway 20 directly through the San Juan Passage housing development downhill to reach trailhead parking area along the water. The trail goes east about 1.2 miles toward the city of Anacortes with plans for eventual completion all the way to city center. This same parking area also serves the Ship Harbor Trail which runs westward toward the WA State ferry terminal. If you get the yen to go to Guemes Island there is a small Skagit County ferry that makes regular 5-minute crossings from downtown Anacortes.
