The road up Parowan
The steepest paved state route in Utah
The Patchwork Parkway, from the bottom of it.
State Route 143 leaves the top of Parowan and climbs about 4,600 feet in eighteen miles to reach the highest town in Utah. It is a national scenic byway, it is the steepest paved state route in the state, and in winter it is the only way up. Here is the drive from the town that watches the weather on it.
Start here
Eighteen miles, and 4,600 feet of it.
State Route 143 leaves the top of Parowan, goes into the canyon behind the town, and climbs about 4,600 feet in eighteen miles. It is the steepest paved state route in Utah, it reaches a 13 percent grade, and the hardest single mile is the last one before Brian Head. That is not a statistic anybody in Parowan needs looking up; it is a thing they explain to visitors most winters.
It is also a designated national scenic byway, running from Parowan up over the plateau to Panguitch, with a spur through Cedar Breaks National Monument on State Route 148. In summer it is one of the genuinely great drives in the state and people who have done it once come back for it. In January it is a road you plan around rather than one you take for granted.
What makes this Parowan's page rather than Brian Head's is that this is where the road starts. The town at the bottom is the one that watches the weather on it, keeps the chains in the boot, and knows which mile is the problem. The town at the top is the destination, and the destination has its own shelf.

Where the name comes from
Seven men, deep snow and a stack of quilts.
The byway is called Utah's Patchwork Parkway, and the name is not decorative. It comes from a winter in the mid 1860s when the settlement at Panguitch, on the far side of the plateau, ran out of flour. A party of men set out over the mountain towards Parowan to fetch some, and found the snow so deep and so soft that they broke through it with every step and could not make progress.
What they had with them were quilts. They laid one on the snow, walked across it, laid the next one down ahead, moved the first one forward, and repeated that until they had crossed the mountain. They reached Parowan, got flour, and got it home. Whatever has accreted onto the story in a hundred and sixty years of retelling, that is the shape of it, and the quilts are why this road carries the name it does.
It is worth being clear whose story it is. That is Panguitch's founding legend rather than Parowan's, and Panguitch keeps a festival built around it. Parowan's part is the other end: this is where the flour was, and this is where the road starts. When Panguitch gets its own shelf here, the festival will be on it.
A road named for the fact that somebody once got across it by walking on their own bedding. That is a more honest description of this stretch of mountain in February than any signage could manage.
Mile by mile
What is actually on the road up.
The first five miles are canyon: red ledges, the creek, and the turning that leaves for Yankee Meadows and First Left Hand Canyon. That turning is one of the best things in this county and it has its own page, because a reservoir road and a ski highway are two different drives that happen to share a first act.
Then the climbing gets serious, the aspen comes in, and around thirteen miles the road arrives at Brian Head at roughly 9,800 feet, which is the highest incorporated town in Utah. That town, its two ski mountains and its summer bike park are covered properly on the Brian Head shelf, and specifically on the mountain page. This page stops at the town limit on purpose.
A little further on, State Route 148 forks south for Cedar Breaks National Monument, and beyond that the 143 keeps running east over the plateau, past Panguitch Lake and eventually down into Panguitch. The full byway from end to end is a half day if you stop, and the section above Brian Head is quieter than the section below it by a wide margin.
Autumn is when the road earns its reputation. The aspen on the upper half turns through late September and into early October, the maple in the lower canyon turns on its own schedule, and the whole eighteen miles becomes the reason people drive up from three hours away. It is also when the traffic arrives, so an early morning is worth more than a Saturday afternoon.
The season that decides it
In winter this road is the only way up.
From roughly November into late spring, State Route 143 out of Parowan is the sole vehicle access to Brian Head, because the southern approach through Cedar Breaks on State Route 148 closes to cars once there is enough snow on it. Everything that reaches the mountain in winter, including the school bus that carries Brian Head children down to school in Parowan, comes up and down this canyon.
UDOT plows and sands it through the season and can require chains or traction devices when a storm is running. The local habit is to leave earlier than the drive needs, keep chains in the vehicle from November whether or not you expect to use them, and check UDOT's conditions before a storm day rather than after starting.
The direction that catches people is downhill. Coming up a 13 percent grade in poor conditions is mostly a traction problem and you find out early whether you have solved it. Going down is a braking problem on a road you cannot stop on, and that is where the incidents happen. If conditions have deteriorated while you were skiing, waiting an hour is the cheapest decision available to you.
None of this is a reason to avoid the road, and I would rather say that plainly than leave a scary impression. Thousands of ordinary vehicles do this drive every winter without incident, the plow crews are good, and Parowan residents treat it as routine. It is simply a mountain road that asks to be respected, and the towns at both ends of it have long since agreed on that.
Check UDOT before a winter drive, and believe it. Conditions on this canyon can differ completely from conditions in Parowan, thirteen miles and 4,600 feet below. UDOT publishes current road conditions, restrictions and any traction device requirements for State Route 143, and it also publishes the seasonal status of the State Route 148 spur through Cedar Breaks. Both are worth checking the morning of, not the night before, because storms here arrive faster than forecasts move.

The road, answered.
Because of a winter in the mid 1860s. The settlement at Panguitch, on the far side of the plateau, had run out of flour, and a party of men set out over the mountain towards Parowan to fetch some. The snow was so deep and soft that they broke through it with every step, so they laid quilts on the surface, walked across them, moved each one forward in turn and crossed the mountain that way. They reached Parowan, got the flour and got it home. The byway is named for those quilts.
It climbs roughly 4,600 feet across eighteen miles and reaches a 13 percent grade, which makes it the steepest paved state route in Utah, with the hardest single mile being the last one below Brian Head. Brian Head itself is at about thirteen miles. Allow more time than the distance suggests, especially in winter, and be aware that the descent in poor conditions is the harder direction rather than the climb.
Yes. UDOT plows and maintains State Route 143 from Parowan through the whole winter, and it is the only vehicle access to Brian Head in that season because the southern approach on State Route 148 through Cedar Breaks closes once the snow is deep enough. Chains or traction devices can be required during storms. Check UDOT's conditions page the morning of a winter drive, because weather in the canyon can be nothing like the weather in Parowan.
From Parowan it climbs the canyon to Brian Head at about thirteen miles, then continues over the plateau past the State Route 148 spur into Cedar Breaks National Monument, on past Panguitch Lake and eventually down into Panguitch. The full byway end to end is a half day drive if you stop for anything, and the section above Brian Head sees a great deal less traffic than the section below it.
Late September into early October, when the aspen on the upper half of the road turns and the maple lower in the canyon turns on its own separate schedule. It is spectacular and it is not a secret, so an early morning is worth considerably more than a Saturday afternoon. Summer is the other good answer, particularly if you intend to continue on the State Route 148 spur into Cedar Breaks, which is only open in that season.
The road is why Parowan has a second home market.
About one home in six here is held seasonally, and almost all of that is people who wanted the lifts close and a real town's services underneath them. If that is the arrangement you are weighing, I can lay the two addresses side by side honestly, including what each one costs to hold.
