One of the best cycling trails in the western US is the 73-mile-long Trail of the Coeur d’Alenes in northern Idaho. It’s a fully paved, mostly flat trail located in the Idaho panhandle between Plummer and Mullan.

The Trail of the Coeur d’Alenes takes you over the cool-looking Chatcolet Bridge, along Coeur d’Alene Lake and Coeur D’Alene river, past numerous lakes, through wetlands, and through the historic Silver Valley. The birding is fantastic, and you might get lucky like we did and see a moose. The eastern section is often close to I-90, so it’s noisier than some of you will like.

You can cycle a section of the Coeur d’Alenes trail, use a shuttle and bike the whole thing one way in a day, or do a version of what we did and cycle it over two days from two different trailheads.

I think the best section for cycling the Trail of the Coeur d’Alenes is between Plummer and Pinehurst.

Why you need to stay on the trail

The Trail of the Coeur d’Alenes is part of an environmental remediation project. Silver was discovered around 1884 – and because of that a rail line was built. A lot of the Trail of Coeur d’Alenes follows the original rail line – which unfortunately was built with waste rock from the mine and tailings containing heavy metals.

There has been a huge amount of environmental remediation work done on and around the trail. The 15-mile section of trail in the Reservation between Plummer and Harrison has been cleaned up the most with tailings removed to a depth of 12 feet or more!

The rest of the trail has a thick layer of asphalt and gravel barriers. There are loads of signs saying don’t drink the water and don’t sit on the ground to minimize any contact with contaminants. Use common sense.

We stuck to the trail and ate at the picnic tables. All our water was either bottled or brought from home.

What to take cycling on the Trail of the Coeur d’Alenes

We didn’t know what to expect with regard to facilities along the Trail of the Coeur d’Alenes, so we brought a few bike tools, snacks – especially as we did 70 miles the first day, water, rain gear along with a warm hat and gloves.

You will find 17 stops along the trail with toilets and they are all kept very clean. There are also over 35 picnic tables, including some with shelters.

I would recommend taking a lot of water though we did find a cooler full of bottled water you could take if needed. There are also some towns along the route – especially in on the eastern section of the trail where you can purchase cold drinks, coffee, snacks etc.

At the very least carry some high energy snacks so you don’t bonk, a bike pump, patch kit, and an extra inner tube.

You’ll find bike tools at many of the trailheads – but we didn’t know that before we showed up

Our experience cycling the Coeur d’Alenes Trail

Before we showed up at the trailhead in Plummer, I did a lot of online research about cycling the Coeur d’Alenes trail. Mostly what I tried to figure out was where to stay and how much cycling we could do and still have fun in a day.

Our group of three decided to meet in Coeur d’Alenes and spend the night. The next morning, we drove 30 minutes to a large easy-to-find trailhead in Plummer. The plan was to do a 70-mile out and back bike ride to the Bull’s Run trailhead and then drive to Wallace and spend the night. On the second day we’d do a 40 – 50 mile out and back bike ride so we would cover off most of the trail.

We cycled the Trail of the Coeur d’Alenes in the third week of April, before any shuttles are offered. Ideally a one-way shuttle between Plummer and Mullan would be the way to go if you wanted to knock off the whole trail in a day and have a car waiting for you.

Day one cycling the Coeur d’Alenes Trail

We didn’t get going until about 10 AM. But that was okay as it was cool at the start of the day. I particularly liked the bike ride from Plummer through to Harrison. There were cliffs, wildflowers, the bridge, and lots of cycling along Coeur d’Alene Lake. We also had three wild turkeys cross the trail in front of us.

After Harrison the cycling was still fantastic as we rode beside the river and then through miles of wetlands. The bird life was exceptional with great flocks of white pelicans, American coots, great blue herons, cormorants, and ducks galore.

Our turn around point was at Bull Run. By the time we turned around, we could cycle in shorts and t-shirts. We found the final 5 miles with it’s supposed 3% grade, slower going than anticipated – but all in all we had a great day. We finished about 5:30 PM with loads of stops for photos.

Day 2 cycling the Coeur d’Alenes Trail

It was drizzling as we prepared to start off – this time in full rain gear. We found free parking beside the Northern Pacific Railroad Museum.

From there you simply cycle one block to get on the Trail of Coeur d’Alenes under I-90. If you go east, you’ll reach Mullan in 7 miles though it’s almost all uphill. We did not do that part of the trail – and I’m not sorry we missed it, as you don’t get away from I-90 or the noise.

Instead, we cycled west towards Kellogg. It wasn’t a pretty start to the day, but it was a window into the historic mining communities. In Kellogg we stopped just off the trail at The Beanery for a latte to warm us up as we all had numb feet.

About four miles after passing Kellogg, we got back into the woods and spent most of the rest of the cycling day along the peaceful Coeur d’Alene River. We did pass one large open gravel pit where we were mesmerized to see the rock being thrown over the cliff to break up by a large excavator.

On this section of trail, we saw a moose and a lot of people fishing. Our turn around point was just after Gap Rock – where we enjoyed a scenic lunch overlooking the river.
