Mother Urban is an uphill-only trail in Park City. Most of the trail is
open for riding at this time, but construction continues on the lower
portion. When complete, it will join the Treasure Hill trailhead to the
Midmountain Trail. The trail system here is relatively complex and
minimally marked, so an on-trail navigation app is highly recommended if
you want to climb Mother Urban.
Typical terrain for much of Mother Urban -- dense
forest of aspen and fir. Trail review by Bruce on July 29, 2022.
|The portion of the trail that's fully open is the 2.4 miles from the King
Road (at the King Road Connector trail) to Midmountain just south of the
Silver King mine. At this time, the 1.1 mile section from South Sweeney's
to King Road is closed on weekdays 8 am to 4 pm to allow crews to do
finish work. A total of 3.5 miles of trail is currently complete at the
top, plus 1/2 mile of Treasure Hill from the trailhead. The plan is for a
4.4-mile trail. (See the map.)
View south toward the top of Empire
Canyon from Mother Urban. On the lower slopes the trail has patches of
scrub oak and maple.
||The Mother Urban trail will begin at 7100 feet elevation at
the base of Treasure Hill -- located 1/2 mile south of the Park City
Mountain Resort (PCMR) -- and extend a 4.4 miles up to Midmountain at 8200.
The expected riding season is June through early October.

||Treasure Hill Trailhead
This small trailhead, with room for 5 cars, is located on the southern end
of Lowell Avenue 1/2 mile south of the main PCMR parking. You'll need to
climb uphill on Sweeney's Switchbacks or a combination of Treasure Hill
and Sweeney's. Then keep straight (left and downhill) onto South Sweeney
at mile 1.2 from the Treasure Hill trailhead. South Sweeney will cross
Mother Urban after another 0.1 miles. The singletrack 100 feet uphill on
your right is lower Mother Urban, currently called the Treasure Hill

full, drive to the main PCMR parking and pedal uphill via Lowell Avenue.

||South Sweeney's Switchbacks
You can reach South Sweeney's by taking the Sweeney Connector 0.3 miles
south from Treasure Hill's trailhead then keeping straight onto South
Sweeney's where you'll climb 0.7 miles to intercept Mother Urban.
You can also enter South Sweeney from paved streets at Norfolk Avenue
(there's no parking here). Or, you can hit South Sweeney from a short
connector at King Road's first left-hand turn above the city.

On city streets, take Main Street south until you find King Road on your
right. Pedal uphill 0.9 miles to the second left-hand turn. You'll see the
King Road Connector trail on your right. Now look just past the apex of
the turn on your left and you'll see Mother Urban on the south side of the
road. It's 2.4 miles to Midmountain from here.

||Mother Urban is a climbing-only trail, created to take
pressure off Jenni's Trail and the Armstrong Trail as a route uphill from
town to the Midmountain Trail. Of the these three options, Mother Urban is
the hardest while Jenni's Trail is easiest.
We're climbing the trail known as Treasure Hill from

trail will become the bottom of Mother Urban once the excavator reaches
|When complete, the Mother Urban trail will be a 4.4-mile climb from Lowell Avenue
to Midmountain. At this time (August 2022), a small section between the
half-mile Treasure Hill trail -- destined to become the lower segment of
Mother Urban -- and downhill end of the trail-cut remains to be excavated.

The segment of Mother Urban uphill from South Sweeney's Switchbacks is

crossing and the junction with the King Road Connector is closed on

Mother Urban will cross South Sweeney or the South Sweeney Connector
five times. So if you're on South Sweeney you WILL find the trail. The intersections are not marked, but the route here is
obvious at this time because it's the big wide new trail.

|0.3 miles from King Road, Mother Urban will join the
Gravedigger trail. This next segment of the trail is two-way. And it's the
most confusing because of multiple connections to Gravedigger and
Moosehouse -- at least until better trail markers are installed and the
route is ridden in.

Mother Urban. Where I'm standing is two-way trail. To the right is Mother

error. The trail is narrow and rooty and angles slightly downhill. But
hang in there. In 0.2 miles (0.7 from King Road), you'll reach a confusing
intersection of old and new trails. Angle a bit right uphill on Mother
Urban, as Gravedigger continues left and an alternate track of Moosehouse
crosses from uphill. Hopefully, action will be taken to simplify and mark
this area better.

So far, this trail is seeing very few riders. It may succeed at taking
pressure off of Jenni's and Armstrong as a climbing route once it's
complete, but I believe it will be the least popular of the climbing
options. It has some navigation problems in the Gravedigger area that,
hopefully, should be resolved soon. I'll have more to say when the full
trail is complete.
The views from Mother Urban are, well, kind of
mediocre. We're looking north.
On Park City's Main Street, turn right towards
Park City Mountain Resort (PCMR) on Empire Avenue then veer right
again at Silver King Drive. Turn left on Lowell Avenue. The main parking
for PCMR is on your right. This will be your fall-back if the 5 parking
spots at Treasure Hill are full. Continue 1/2 mile south on Lowell Avenue.
The Treasure Hill trailhead is on your right, just before Lowell Avenue
turns downhill to the left and becomes Empire Avenue.
If Treasure Hill is full, continue on Empire Avenue all the way back to
Silver King Drive and turn left for main PCMR parking. (Note that one
segment of Lowell Avenue is one-way, so don't do a U-turn to return to
NOTE: Map shows status as of July 29, 2022. It will be updated
when the trail is complete down to Treasure Hill. (The purple trail from
Treasure Hill on the map's upper right will become lower Mother Urban once
the trail-cat makes the connection.)
