What to expect at Mirror Lake

Mirror Lake sits at 10,380 feet in the Uinta Mountains, about 30 miles northeast of Kamas. The lake holds cutthroat trout and lake mackinaw (Dolly Varden), with cutthroat the primary target for most anglers. The water is cold and clear, and the season runs from late May through October, depending on snow melt and road conditions. Access is straightforward—a paved highway takes you to the parking area, and the lake sits just a short walk from the road.

The lake spans roughly 40 acres and averages 30 to 40 feet deep. Cutthroat here run 10 to 14 inches on average, with occasional fish to 16 inches. Mackinaw are present but less common in the catch, though they grow larger and deeper than the cutthroat. The shoreline is rocky and forested, with a few established campsites nearby. Weather changes fast at this elevation—afternoon thunderstorms are common in summer, and temperatures drop sharply after sunset.

Key Takeaways

  • Mirror Lake opens when the road clears, typically late May, and closes when snow makes the highway impassable, usually by November.
  • Cutthroat trout are the main species; they respond to small spinners, flies, and live insects, especially in early morning and evening.
  • A Utah fishing license is required, and the lake is open year-round by regulation but inaccessible in winter due to snow.
  • The parking area fills on weekends and holidays; arrive early or fish on weekdays to avoid crowds.
  • Camping is available at Mirror Lake Campground, a few hundred yards from the water, with sites that book through recreation.gov.

Seasons and access

The road to Mirror Lake (Forest Road 150) is typically passable from late May through October. The exact opening and closing dates depend on snowfall and road maintenance by the U.S. Forest Service. Call the Kamas Ranger District at 435-783-4338 to confirm current conditions before driving. The parking area is paved and holds roughly 30 vehicles; it fills by mid-morning on summer weekends.

The walk from parking to the lake is less than a quarter mile on a maintained trail. No boat launch exists, but the shoreline is accessible for wading and shore fishing. Winter access is not practical—the road closes to regular traffic, and the lake freezes solid by December.

What fish are here and how to catch them

Cutthroat trout dominate the catch. They are aggressive and not particularly selective, making Mirror Lake a good choice for anglers who want consistent action rather than technical fishing. Small spinners (size 0 to 2) in silver or gold work well, as do small spoons. Fly anglers do well with nymphs and small streamers, particularly in the early morning and in the hour before sunset.

Live insects—grasshoppers in late summer and aquatic nymphs in spring—produce steady results. The cutthroat will take bait, but spinners and flies offer more sport and are easier to manage in a catch-and-release setting. Mackinaw are deeper and less predictable; they respond to larger lures and live baitfish, but most anglers do not target them specifically.

The lake has no inlet or outlet visible from shore, so fish concentrate along the deeper drop-offs and rocky points. The north and east shorelines tend to hold more fish than the shallow western side. Early morning and the last two hours before dark are the most productive times.

Regulations and licensing

Utah requires a valid fishing license for anyone 16 and older. Licenses are sold online through the Utah Division of Wildlife Resources website, at sporting goods stores, and at ranger stations. A one-day license costs less than a full-year license and is a reasonable choice if you are visiting for a single trip.

Mirror Lake is open year-round by state regulation, but the road closure makes winter fishing impossible. The lake is managed as a cutthroat fishery with a standard bag limit of four fish per day. No special restrictions apply—standard Utah trout rules govern the lake. Check the current Utah fishing guidebook before you go, as regulations can change.

Camping and lodging nearby

Mirror Lake Campground sits a short walk from the parking area and offers the most direct option. The campground has roughly 80 sites, most with a picnic table and fire ring. Water and vault toilets are available, but there are no hookups. Sites book through recreation.gov and fill quickly on summer weekends; reservations open several months in advance.

If Mirror Lake Campground is full, several other Forest Service campgrounds lie within 15 to 20 miles: Hayden Fork, Shady Dell, and Lost Lake all offer similar amenities and are less crowded. Kamas, 30 miles southwest, has motels and restaurants if you prefer not to camp. The nearest town with full services is Park City, about 40 miles away.

Gear and preparation

Bring layers—the elevation means cool mornings and cold evenings even in July. A light rain jacket is essential; afternoon thunderstorms are common and can arrive quickly. Sunscreen and a hat are important because the water reflects UV light intensely at this altitude.

A 5- to 6-weight fly rod works well for cutthroat here, as does a light spinning rod with 4- to 6-pound test. Waders are optional but useful if you want to wade into deeper water; the shoreline is rocky and slippery. Bring a headlamp or flashlight if you plan to fish the evening bite—the sun sets early at this elevation, and the trail back to the parking area is dark by 8 p.m. in summer.

Crowds and timing

Mirror Lake is popular, especially on summer weekends and holidays. The parking area fills by 10 a.m. on Saturdays and Sundays from June through August. If you want solitude or shorter lines at the water, fish on weekdays or in May and September when the weather is still good but crowds are lighter.

The first two weeks of June and the last two weeks of September offer the best combination of reliable access, fewer people, and good fishing. July and August are warmest but most crowded. Early morning fishing (before 8 a.m.) also reduces encounters with other anglers, even on busy days.

Frequently Asked Questions

Can I fish Mirror Lake in winter?

The road closes to regular traffic by November, making winter access impractical for most anglers. The lake freezes solid, and the Forest Service does not maintain the highway during snow season. Spring is the earliest reliable time to fish.

Do I need a boat to fish Mirror Lake?

No. The shoreline is accessible for wading and shore fishing. No boat launch exists, and the lake is small enough that shore fishing covers most productive water. Waders make it easier to reach deeper areas, but they are not required.

What is the best time of day to fish?

Early morning (sunrise to 9 a.m.) and the last two hours before sunset produce the most consistent action. Midday fishing is slower, though cutthroat will still bite. Cloudy days are often better than bright, clear days.

How far is Mirror Lake from Salt Lake City?

Mirror Lake is roughly 50 miles northeast of Salt Lake City, about an hour and 15 minutes by car. The drive follows I-80 east to Kamas, then heads north on Highway 150 into the Uinta Mountains.

What should I do if the campground is full?

Several other Forest Service campgrounds within 15 to 20 miles offer similar fishing access and are often less crowded. Hayden Fork and Shady Dell are nearby alternatives. Kamas and Park City both have motels if you prefer not to camp.
