Park City Hiking Trails: How Altitude and Season Decide Your Hike
Contents
If you came for a ranked list of the ten prettiest hikes, Park City does not work that way. What exists is one interconnected system: approximately 400 miles of continuous, non-motorized recreational trail. Mountain Trails Foundation, a donor-driven non-profit that became a 501c3 in September of 1993, describes its job as building, maintaining and protecting trails for non-motorized recreation in the Park City area, and it publishes the trail etiquette and the current trail report. Visit Park City markets the same thing as a 400-plus mile network.
The two variables that decide whether your hike is good are altitude and season, not scenery. Mountain Trails Foundation publishes a typical alpine season of June through November and an elevation band from 6,500 feet to nearly 10,000 feet, and notes that lower areas such as Round Valley and Glenwild can open up to six weeks earlier. The dirt can be dry in Round Valley while the trail to 10,000-foot Jupiter Peak is still buried, and both are true on the same morning. Everything below is built around that, plus the etiquette you need because the singletrack you walk also carries bikes, horses and dogs.
Key takeaways
- Park City is one system of roughly 400 miles of continuous non-motorized trail, maintained by Mountain Trails Foundation, a 501c3 since September 1993.
- The published alpine season is June through November, but Round Valley and Glenwild can open up to six weeks earlier.
- The network spans 6,500 feet to nearly 10,000 feet, so snowmelt, mud and storms arrive on different schedules depending where you start.
- Trails are shared-use: bikes always yield to hikers, even uphill, and e-bikes are banned on singletrack except riders 65 and older or with a mobility disability.
- The guide’s named short hikes are a genuinely short list: McPolin 1.5 miles, PC Hill 1.8 miles, Silver Spur-Armstrong-Dawns 4 miles.
There is no top ten, there is one network
The important fact here is structural. Mountain Trails Foundation states that over 400 continuous miles of non-motorized trail now exist in Park City, and its summer overview puts it bluntly as 400 miles of singletrack. Continuous is the operative word: these are not isolated trailheads, which is why the town holds IMBA Gold Level Ride Center status with the Mid Mountain and Park City Epic routes designated as IMBA Epic rides. For a hiker, that means you are not choosing a trail so much as choosing an elevation, a direction and a turnaround time. The Mid Mountain Trail hovers right around 8,000 feet, which makes it less a destination than a contour line you join, follow and leave.
Season and altitude decide your day
Start with the calendar the foundation publishes. June through November is a statement about nine-thousand-foot terrain, not about the town generally. Round Valley sits at 7,202 feet and Glenwild at 7,766 feet, and both can open up to six weeks earlier, while the same network tops out at 9,986 feet at Park City Mountain and 9,658 feet at Deer Valley. A six-week head start at the bottom and a June opening at the top is the whole spring shoulder season in one sentence.
The practical version: early in the year, do not drive uphill looking for dry trail. Drive downhill. Round Valley alone holds 56 miles across 2,100 acres of rolling, high-desert terrain, including over 50 miles of beginner and intermediate singletrack.
The trail areas, sorted by how high they are
Sorting by elevation rather than beauty gives you a planning tool. The lower rows melt out first; the higher rows are where the June-through-November window really applies.
| Trail area | Miles | Elevation | What it is |
|---|---|---|---|
| Round Valley | 56 | 7,202 ft | 2,100 acres of rolling high desert; beginner and intermediate singletrack; dogs off-leash per signage |
| Lost Prospector | 11 | 7,586 ft | Reachable from town via the Rail Trail; lunch loop is Freemason, Lost Prospector and Skid Row |
| Glenwild | 44 | 7,766 ft | North of Kimball Junction; a lower-lying area that can open up to six weeks earlier |
| North Basin | 23 | 8,390 ft | Maintained by Basin Recreation; Summit Park trails described as shady getaways in hot months |
| Utah Olympic Park / Canyons Village | 34 | 8,433 ft | 316 acres near Kimball Junction; includes the Run-A-Muk off-leash dog area |
| Deer Valley | 41 | 9,658 ft | Six mountains, up to 3,000 vertical feet of elevation change |
| Park City Mountain | 109 | 9,986 ft | Starts in Old Town, spans 3,000 vertical feet, includes 10,000-foot Jupiter Peak |
Read that as a season chart, not a leaderboard. Roughly 2,800 feet separate the top row from the bottom, which is why one week can be perfect at Round Valley and out of the question at Jupiter Peak.
The short hikes the guide actually names
If you want named routes with published distances, the honest list is three. The official Park City trail guide map gives the McPolin Nature Trail at 1.5 miles and about an hour, the PC Hill Trail at 1.8 miles top and back in 1 to 2 hours, and Silver Spur-Armstrong-Dawns at 4 miles, also 1 to 2 hours. All three fit inside a half day.
They cover most first-visit needs precisely because they are short and low. An hour on McPolin doubles as a read on whether the weather will hold. PC Hill is an out-and-back, so the turnaround is built in. The 4-mile Silver Spur-Armstrong-Dawns route is the step up; check the trail report first, since Armstrong has been subject to closure for municipal fuel-reduction work.
The Rail Trail is the exception to all of this
One route is described by mileage rather than elevation. The official Park City trail guide lists the Historic Union Pacific Rail Trail at up to 27 miles; Rails-to-Trails Conservancy’s TrailLink lists the Historic Union Pacific Rail Trail State Park at 28 miles, running between Echo Reservoir at Coalville and the Poison Creek Trail at Bonanza Drive in Park City. Those figures disagree slightly.
Surface and grade matter more than the mileage. TrailLink describes it as primarily gravel except for 3 miles from Park City north and a 0.5-mile section in Wanship, which are paved. A rail corridor follows a former railway alignment, it starts in town, and it is the connector that puts Lost Prospector within walking reach. When the alpine season has not opened, this is the fallback that does not depend on the high country.
The rules of the trail are the real article
Because these trails carry hiking and trail-running, mountain biking and equestrian users at once, the published etiquette is not decoration. Bikes should always yield to hikers, even if traveling uphill. Among bikes, uphill riders have the right of way over downhill riders. E-bikes are prohibited on singletrack, with a legal exemption for e-MTB riders 65 years and older and those with a mobility disability.
Dog rules are equally specific. Dogs must be leashed immediately upon arriving at trailhead parking lots and on any wildlife encounter, and owners are expected to remove dog waste regardless of where it falls. Off-leash use is published for Round Valley subject to signage, and the Utah Olympic Park area includes the Run-A-Muk off-leash area. Outside those, assume leashed and read the trailhead signs.
Pro tip
As a hiker you hold right of way over every bike on the mountain, uphill or downhill. Use it thoughtfully rather than aggressively: step to the downhill side of the tread, stay visible on blind corners, and call out how many people are behind you.
Weather is the other half of the altitude problem
Summer temperatures here can vary as much as 40 degrees in a single day. That alone should change what is in your pack. Summer storms, though typically brief, often cause sudden downpours of heavy rain or hail with temperatures plummeting 25-plus degrees. A 25-degree drop while you are wet, above 9,000 feet and an hour from the trailhead, is serious, not an inconvenience.
Most of those storms bring lightning, and the guidance is unambiguous: if thunderheads develop, get off the mountain quickly. Treat exposed high ground as a morning objective, fix a turnaround time before you leave, and carry a shell even on a clear June morning.
Common mistake
Walking a wet trail because you already drove out there. The published rule is that if snow or dirt is too wet or soft to ride a straight line, turn around, and the trail report repeats it for every user: if the trail is too wet, turn back or wait. A rut left in soft tread is exactly what that rule exists to prevent.
Closures move trail by trail, not by season
An open season does not mean an open trail. As of the current trail report, the Iron Mountain Hiking Trail and the Armstrong Trail were closed for Park City Municipal fuel-reduction work, with crews actively felling trees near the trail and a request not to enter the Armstrong corridor during closure hours. That is a work-by-work closure, not a seasonal one, and it can appear or disappear between visits.
The network also changes underfoot: a new 9K to Mid Mountain hiking trail has been under construction with roughly 100 feet of tread remaining. Checking the trail report the morning you go catches both problems, and tells you whether the dirt is dry enough to walk on.
How to actually plan the day
Work the decision in this order: season, elevation, distance, scenery. If the alpine window is not open, choose from the lower rows of the table above, where Round Valley and Glenwild can be walkable up to six weeks before the high country. Then pick a distance you can finish before the afternoon builds. For a first visit that usually produces a short named hike, a low-elevation area, and the Rail Trail held in reserve for the day the weather turns.
Frequently asked questions
When do the Park City hiking trails open for the season?
Mountain Trails Foundation publishes a typical alpine trail season of June through November. Lower areas such as Round Valley and Glenwild can open up to six weeks earlier, so the shoulder season exists only at the bottom of the 6,500-foot to nearly 10,000-foot band.
Do hikers have to share the trails with mountain bikes?
Yes. The network is open to hiking and trail-running, mountain biking and equestrian users on the same tread. Bikes should always yield to hikers, even traveling uphill, and among bikes, uphill riders have right of way over downhill riders.
Are e-bikes allowed on Park City singletrack?
No, with one exception. E-bikes are prohibited on singletrack, but e-MTB riders 65 years and older and those with a mobility disability are legally allowed on it.
Can I bring my dog?
Dogs must be leashed immediately upon arriving at trailhead parking lots and on any wildlife encounter, and owners must remove dog waste regardless of where it falls. Off-leash use is published for Round Valley subject to signage, and the Utah Olympic Park area includes the Run-A-Muk off-leash dog area.
What is a good short hike for a first visit?
The official trail guide names three with published distances: McPolin Nature Trail at 1.5 miles and about an hour, PC Hill Trail at 1.8 miles top and back in 1 to 2 hours, and Silver Spur-Armstrong-Dawns at 4 miles in 1 to 2 hours. Check the trail report first, since Armstrong has been subject to closure.
How long is the Rail Trail, and is it paved?
Published figures differ. The Park City trail guide lists the Historic Union Pacific Rail Trail at up to 27 miles, while TrailLink lists it at 28 miles between Echo Reservoir at Coalville and the Poison Creek Trail at Bonanza Drive. The surface is primarily gravel except for 3 paved miles north out of Park City and 0.5 paved miles in Wanship.
