It’s a beautiful trail, much of it deviates from the main highway and the stretch between Midvale and Weiser was remote and amazing. The trail material is horrible though. Large angular gravel beats the crap out of you and your bike. Did the trail in two days and took three days for my kidneys to recover from the constant shaky and bumpy ride. I strongly recommend staying away from the Weiser to Weiser canyon stretch. That part was extremely brutal. Park at the parking area near the entrance to the canyon.
Boise is a beautiful city, and this trail is great if you like that kind of riding. It's somewhat kinda closed in and you don't really get any views of the mountains or the river. Lotsa people on the trail as well.
I rode this trail the last weekend in September on an overcast morning, and loved it! I loved the rural feel and the colorful mountains in the distance. The last mile or two we biked through a canopy of yellow trees on a winding path. Gorgeous!
This is a wonderful ride. This is an easy 15 mile descent with amazing views. Expect to get dirty and wet going through the tunnels. Pack a lunch. E-Bikes have no need to shuttle. Highly recommend.
When I first heard about this trail MANY (27) years ago, I said, "This must go on my bucket list!" This late July I crossed it off, finally. All I can say is that this trail is all that it is cracked up to be and MORE!! I was definitely living the dream!
The only bummer was having to rent bikes because we flew out! They were not the best because, of course, one gets comfort from their own ride. My husband's bike kept breaking. We had to fix it once on the trail side, with the help of volunteer Trail Patrol (Yep, they got 'em) and again at the bottom before our ride back up. We had decided to make the dream last.
I recommend checking out their web site, as there is very much needed info and you will know about special events that may hinder your experience.
We saw quite a few families with littles as young as 5 years old. The slow decent makes it ideal for them and there is a shuttle bus service to take you back up.
I just might ride again but I'll bring my own bike next time.
Excellent trail. Fields, hills, cows, trestle bridges; full 30 miles end to end! Was warm when we rode however there is shade along the way.
Here from Phoenix and loved the trail Wasn’t all paved but still good and pretty smooth. Will do it again before we leave to head home. Parked at Reid Merrill Park as we were early enough to get a spot. Lots of walkers with dogs and other bikes and it was morning on a Friday. Good trail
We rode this trail 3 times and covered from Bellevue to Ketchum and the Sun Valley loop. It is very well maintained and completely asphalt. There’s some shaded riding in a few spots but mainly out in the open so expect to be in the sun for most of it.
I rode this in the reverse direction from Taft to Mullan as part of a bikepacking trip in July 2025. The NorPac was one of the highlights of the trip, with smoother gravel than the Old Milwaukee Trail or the Route of the Olympian. From Taft (the freeway exit for the Hiawatha Route), the trail is fairly easy to find. Just go back on the frontage road past some large industrial buildings, and the trail will start up the mountain underneath I90.
The Borax Tunnel is indeed closed, however, it would be very difficult to even access it. The bypass road is very clearly the only route to take, and while steeper than the rest of the trail, it is not long or too steep (6-7% gradient). The original trail to the tunnel is blocked by a huge piles of old trees at the bottom and a large berm at the top.
Lookout Pass has a few snacks, similar to the East Portal trailhead of the Hiawatha. Staying on the gravel road on the otherside of the parking lot, it eventually narrows and once again you're descending on smooth dirt down the Idaho side. It would be difficult to get lost. There is a major junction with a hard right turn and another instance where the trail bypasses the Shoshone Park road.
If you're coming from the Idaho side to start, the easiest way to describe how to access the trail is to navigate to the Fish Hatchery, and then make a 90 degree turn to the left and enter the trail through the trees.
I rode this trail in the opposite direction as part of a multi-day bikepacking trip in July 2025. In general, the whole thing is pretty flat/slightly uphill, with the section between Marble Creek and Avery on Siberts Old River Road adding a little bit of up and down hills. The road is rocky and tough on the arms. I had 700x40 inch tires on a carbon gravel bike and definitely felt it that night. We averaged around 11 MPH, imagine you could do better going the downhill route. Spectacular views, particularly between Pearson and Avery, where you go through about seven tunnels and have towering pine-covered mountains and a deep river canyon below.
