The Milky Way casts shadows over this empty Utah lake 8,800 feet up

Fish Lake’s secret is older than you think

Fish Lake sits above 8,800 feet in the middle of Utah, and most people have never heard of it. The lake runs six miles long and drops 120 to 160 feet at its deepest point.

Trout grow to 50 pounds out there. A single aspen tree covers 106 acres just down the road.

The dark skies here are so clear the Milky Way casts a shadow. All of it sits inside Fishlake National Forest, quiet and largely uncrowded, waiting.

A valley that fell between cracks in the Earth

The lake didn’t form the way most do. It fills a graben, a chunk of land that dropped down between fault lines in the Earth’s crust.

The Mytoge Mountains rise about 1,000 feet along the southeast shore, and the Fish Lake Hightop Plateau pushes nearly 11,600 feet to the northwest. Those two walls cup the water from both sides.

You feel it when you arrive: the lake sits at the edge of Colorado Plateau country, boxed in by geology that took millions of years to arrange itself just like this.

The 50-pound trout living in the deep water

Fish Lake built its reputation on mackinaw, and the fish live up to it.

The Forest Service says lake trout here can push past 50 pounds, and anglers go after them in boats over the deepest sections.

If mackinaw aren’t your target, the lake also holds rainbow trout, splake, brown trout, kokanee salmon, tiger trout, and yellow perch.

Most serious fishing happens out on the water, away from shore, where the depth holds the cold that big trout prefer.

Paddle at dawn while the peaks reflect below you

The lake is wide enough for motorboats, and fishing rigs move across it all day in summer. But on calm mornings, kayaks and canoes own it.

The water stays cold even in August at this elevation, so you won’t be tempted to swim far.

What you will do is drift on glass-flat water while the Mytoge Mountains reflect beneath your hull, the light turning gold and then purple as the sun clears the ridge.

Paddleboards work well here too on those still summer mornings.

Walk the shore or climb to the high country

The Lakeshore National Recreation Trail follows the eastern side of the lake with wide, open views across the water the whole way. It’s an easy walk.

If you want more, the Pelican Canyon Trail climbs about five miles toward the Fish Lake Hightop Plateau and pays you back with a sweeping look down into the whole basin.

You’ll see the lake spread out below, the peaks on both sides, and the aspen forest rolling across the middle slopes. The basin has routes for both easy days and hard ones.

In fall, the hillsides go gold all at once

Quaking aspen covers the slopes around Fish Lake, and when October hits, those hillsides flip to gold with orange and red working through the mix.

The leaves flutter in the lightest breeze, which is something aspen do because of the flat stems on their leaf stalks, so the whole forest seems to shimmer and move.

The scenic drive between Fish Lake and the town of Loa is one of the better leaf-peeping routes in Utah, and the dark green of the evergreens makes the color pop harder against it.

One aspen root system blanketing 106 acres

Just southwest of Fish Lake, there’s a grove that looks like a forest but isn’t.

Pando is a single quaking aspen organism, meaning every stem you see, tens of thousands of them spread across 106 acres, grows from the same root system. Scientists put its age in the thousands of years.

You can pull over on the scenic byway and look right into it. Nothing marks the edges of where this one plant ends, because it doesn’t, really.

It just keeps going through the ground beneath your feet.

Mule deer, moose, and black bear share this basin

You’ll see mule deer at the water’s edge most mornings, sometimes in small groups grazing the meadow near the shore.

Moose, elk, and mountain goats live in the area too, with black bear and cougar ranging through the wider forest. Wild turkeys move through the aspen groves, and songbirds fill the trees in summer.

The basin holds more wildlife than most people expect when they arrive.

Drive the road slowly in the early morning or around dusk and you’ll see why the locals barely slow down anymore for deer.

The Milky Way stretches bright across the whole sky

Fish Lake sits a long way from any city, high in clean mountain air, and at night that combination does something to the sky you don’t see most places.

The Milky Way comes out clear and full, not as a faint smear but as a wide band of light across the dark. The high elevation cuts down the atmospheric haze that blurs stars at lower elevations.

Most people who camp here say the night sky alone is worth the drive. Bring a blanket and plan to stay up later than you normally would.

The lake freezes over and the anglers come back

Ice fishing season at Fish Lake usually starts around New Year’s when the ice thickens enough to hold. Some years it holds into March.

The winter basin goes quiet under snow, the crowds gone, the motorboats stored away.

In recent years, more anglers have shown up in winter than in summer, which tells you something about how good the fishing gets when the lake ices over. The mackinaw are still down there in the deep cold water.

Getting them through a hole in the ice is a different challenge, but the fish are the same size.

Waterbirds, raptors and songbirds along the shore

The wetlands and shallows along the lake’s edge draw waterbirds in numbers. Raptors work the ridgelines and catch thermals above the peaks.

Songbirds move through the aspen groves in spring and summer, and the meadow edges add another layer of habitat where different species come and go.

Spring is the most active season for birders, but summer has steady activity too. You don’t need to be a serious birder to notice how full of life the lake’s edges are from early morning on.

Fremont petroglyphs carved into the canyon rock

Fremont Indian State Park sits within Fishlake National Forest and holds the largest Fremont settlement ever discovered.

Carved and painted figures cover the canyon walls, left by the Fremont people who lived in this part of Utah long before European contact. You can walk through and read the rock art up close.

The park is also a certified dark sky park, so if you’re already planning a night of stargazing at Fish Lake, this site rewards a second evening under the stars just a short drive away.

Reach Fish Lake in Utah’s Fishlake National Forest

You get to Fish Lake by taking Utah Highway 25 off Highway 24, with the town of Richfield serving as the nearest hub for supplies and lodging if you need them.

Six Forest Service campgrounds sit in the basin along with three lakeside resorts that have cabins and RV hookups.

Peak season runs roughly Memorial Day through Labor Day, though the road stays open in winter except during heavy storms.

ATVs are not allowed in the Fish Lake Basin, so leave them trailered until you’re outside the basin boundaries. Capitol Reef National Park makes a solid extension for the drive back.
