Bingham Creek to Rattlesnake Gulch: Millcreek Shade Laps

As an Amazon Associate I earn from qualifying purchases.

Late August in Millcreek Canyon means two things. Dust that sits deep and shade that matters more than ever. If you have been fighting loose corners in Corner Canyon or baking on exposed Wasatch Crest traverses, Bingham Creek to Rattlesnake Gulch is the reset lap that still feels fast. It stays cooler, it holds moisture longer, and it links together a climb you can settle into with a descent that rewards pumping over braking.

This is a trail guide for a local favorite that does not get the same hype as Wasatch Crest. It is also a setup and line choice guide for making any dusty Millcreek ride faster right now. The shade line is the fast line.

Why This Lap Works in Late August

Millcreek Canyon runs north facing for much of this loop. That matters in late August when south facing trails in Corner Canyon turn to moon dust by noon. Bingham Creek holds shade from big pines and maples through morning, and Rattlesnake Gulch stays tucked enough that the top inch of soil keeps a little bite until evening.

It also solves the heat problem. You climb in shade, you contour in shade, and you descend with trees breaking the wind that usually blows out berms. For a Wasatch local trying to get a quality hour after work, this is one of the few loops where you can ride hard without overheating or washing out in deep dust.

If you have been working on late August moves for dust, heat, and speed, this lap is the place to practice them. The same ideas about staying off the brakes and weighting the front wheel apply here, but the penalty for getting it wrong is lower.

The Route: Bingham Creek to Rattlesnake Gulch Loop

This is a 5.5 to 6.5 mile loop depending on where you start in Millcreek, with about 900 feet of climbing. It is best ridden clockwise to keep the technical bits downhill. Ride it as a standalone or add it to a Pipeline extension if you want more miles.

Parking and Start

Park at the Bingham Creek lot just past the winter gate area in Millcreek Canyon. If that is full, the next pullout up canyon works and adds a short road spin. Both spots get busy after 5 pm, so aim for early morning or right before sunset. Bring a Northwest fee pass or pay at the kiosk.

Roll up the road for two minutes then drop into Bingham Creek on the left. The entry is easy to miss. Look for the singletrack cutting off the main trail just after the bridge.

Climb

Bingham Creek climbs steadily for about 1.2 miles. It is not steep, but it is rooty with a few rock steps. In late August the roots are dry and polished, so keep your weight centered and look two bike lengths ahead. Spin a gear you can stay seated in. Standing spikes rear tire slip in this dust.

The climb tops out at a junction with the Great Western Trail. Take a breath here. This is the shadiest spot on the loop and a good place to check tire pressure with your hand. If your tires feel rock hard, you are over inflated for this soil. See our tire pressure myth guide for why lower is faster in Wasatch dust.

Traverse and Descent via Rattlesnake Gulch

From the junction, go north on Great Western for about half a mile. This traverse is the key to the whole ride. It stays high, it stays in trees, and it keeps your speed without pedaling. Pump the small rollers instead of braking into them. That is the same technique we covered in pump for free speed, and it saves your brakes for the real descent.

Drop into Rattlesnake Gulch on the right. The upper third is tight, with duff and a few off camber roots. The middle opens into fast, slightly bermed turns where the dust gets deepest. Stay high on entry, look to the exit, and let the bike float. Do not drag rear brake through the whole turn. Brake before, release, then pump out.

The lower third kicks out to Pipeline. You can either take Pipeline back to Bingham Creek for a lollipop or dive back into the bottom of Bingham Creek for a figure eight. Both end at the road within five minutes of your car.

5 Moves That Keep Speed When It Gets Loose and Hot

These are not fitness tips. They are line and brake choices that work right now in Millcreek dust.

1. Brake on the straight, not in the turn. Late August dust piles up in the outside of Millcreek corners. If you brake in the turn, your front tire pushes into that loose pile and washes. Brake early on the straight, then release and lean the bike, not your body.

2. Weight the front on roots. Dry roots are slick if you unweight the front. Keep elbows bent, chest low, and hands light but forward. The front tire needs to bite first.

3. Look for the dark dirt. In Bingham Creek, the fast line often has slightly darker soil. That is where a little moisture remains or where traffic has packed the dust. Light tan powder is slow. Darker brown is grip.

4. Drop 2 to 3 psi from your summer high. If you have been running 28 psi rear in Park City, try 25 or 26 here. The duff and roots reward a bigger contact patch. For reference, our Wasatch trail tire picks all seal well tubeless at these pressures when tape and valves are fresh.

5. Hydrate before the climb. Millcreek feels cooler than Corner Canyon but you still lose water fast at elevation. Sip 6 to 8 ounces before you start climbing, not just at the top. A low profile pack keeps weight off your back in heat.

Setup Tweaks for Millcreek Dust

Late August is hard on drivetrains. Dust plus chain lube equals paste. If you have not cleaned your chain this week, do it before this ride. A dry or wax based lube holds up better here than wet lube that attracts dust. Wipe the chain after every ride, even a short one.

Brake pads glaze quickly in dusty conditions. If your brakes howl on Rattlesnake, scuff pads lightly with sandpaper and clean rotors with isopropyl alcohol. Check our quiet brake notes for Corner Canyon and Millcreek for pad compounds that stay quiet when it is dusty.

Dropper post matters more on this loop than on smoother Wasatch trails. The entry into Rattlesnake is steep and loose, and having the post fully down lets you keep weight back without locking your arms. If your post has been slow, service the air pressure and check cable tension before you ride.

Timing, Water, and Trail Etiquette

Millcreek Canyon has odd and even day rules. Bikes are allowed on upper Millcreek trails only on even numbered days. Bingham Creek and Rattlesnake Gulch follow that rule, so plan accordingly. Check the Forest Service gate sign on your way up. It lists the day type.

Best timing right now is 7 to 10 am or 6 to 8 pm. Midday heat still hits 85 to 90 in the lower canyon, and dust hangs in the air after heavy traffic. Evening laps are fastest because the soil has had shade all afternoon and has not been blown out yet by downhill traffic.

Bring 20 to 24 ounces of water for one lap, more if you extend on Pipeline. There is no water in the canyon. A 1.5 liter pack is plenty and fits better than a bottle in a cage on rooty climbs.

Yield to uphill riders and hikers. Millcreek is mixed use and gets crowded. A bell helps on blind corners in Rattlesnake. If you see horses, stop, step off the downhill side, and talk calmly so they know you are a person.

FAQ

Where do you park for Bingham Creek to Rattlesnake Gulch?
Park at the Bingham Creek lot in Millcreek Canyon just past the winter gate. If it is full, use the next pullout up canyon and ride the road back two minutes to the Bingham Creek singletrack entry on the left after the bridge.

Is this loop bike legal every day?
No. Upper Millcreek trails including Bingham Creek and Rattlesnake Gulch allow bikes only on even numbered days. Check the Forest Service sign at the canyon mouth for the day type before you go.

What tire pressure works best in late August Millcreek dust?
Most riders are faster at 25 to 27 psi rear and 22 to 24 psi front on 2.4 to 2.5 inch tubeless tires for this loop. That is 2 to 3 psi lower than hardpack summer pressure. It increases grip on roots and loose over hard without raising flat risk if your sealant is fresh.
