A Brief History of the Frank Church-River of No Return Wilderness
Located in central Idaho, the Frank Church–River of No Return Wilderness is characterized by rugged mountains, deep canyons, and wild rivers.
Indigenous peoples, including the Nez Perce and Shoshone-Bannock tribes, have inhabited this area for thousands of years. The Salmon River is rich in artifacts and pictographs, indicating human presence dating back 8,000–10,000 years. The challenging terrain provided a natural refuge, fostering a deep cultural connection to the land.
The “River of No Return”
The Lewis and Clark Expedition encountered the Salmon River in 1805. They famously named it the “River of No Return” due to its treacherous currents.
The Idaho Gold Rush in the 1800s brought fur trappers and miners to the area. Boom towns briefly appeared but quickly faded, leaving behind ghost towns and faint trails in the remote wilderness.
These harsh conditions limited settlement.
Conservation Efforts
As the nation began prioritizing the protection of public lands, this wild region gained recognition. The U.S. Forest Service established the Idaho Primitive Area in 1931, encompassing 1.09 million acres.
The 1964 Wilderness Act further expanded protection. In 1980, Congress officially designated the River of No Return Wilderness, combining the Idaho Primitive Area with adjacent lands.
This created a vast, interconnected wilderness of nearly 2.4 million acres.
Honoring Senator Frank Church
The wilderness was renamed in 1984 to honor Senator Frank Church, a staunch advocate for wilderness preservation. He had passed in April of that year.
Today, much of this area remains untouched, devoid of roads or permanent structures, aside from a few historical cabins. The U.S. Forest Service manages the wilderness, and 236 miles of the Salmon River are protected under the Wild and Scenic Rivers Act.

Best Fly Fishing Lakes in Frank Church River of No Return Wilderness
The Frank Church–River of No Return Wilderness in Idaho is a fly fishing paradise, with its pristine alpine lakes, remote streams, and wild rivers teeming with native trout. While the Salmon River and its Middle Fork often steal the spotlight for river fishing, the wilderness is dotted with high-country lakes that offer exceptional fly fishing opportunities, especially for those willing to hike or pack in. These lakes are known for their solitude, stunning scenery, and healthy populations of cutthroat, rainbow, and brook trout. Here’s a rundown of some of the best fly fishing lakes in the wilderness, based on their fish populations, accessibility, and reputation among anglers.
Top Fly Fishing Lakes
- Ship Island Lake (Bighorn Crags)
- Location: Eastern part of the wilderness, near Crags Campground
- Distance: 13.1 miles round trip from the trailhead
- Fish Species: Cutthroat trout, rainbow trout
- Highlights: The largest lake in the Bighorn Crags, Ship Island is a gem for fly anglers. Surrounded by jagged granite peaks, it’s stocked naturally with cutthroat and rainbow trout that thrive in its clear, cold waters. The lake’s size (over 200 acres) and depth support a robust fishery, and fish are known to rise eagerly to dry flies like Adams or elk hair caddis.
- Why It’s Great: Remote and scenic, with consistent action for 10–14-inch trout. Late summer (July–August) is prime time when snowmelt subsides and fish are active.
- Access Tip: Hike in from the Crags Campground trailhead (2–3 hours one way); pack light for an overnight stay.
- Cathedral Lake (Bighorn Crags)
- Location: Near Ship Island Lake in the Bighorn Crags
- Distance: 8.8 miles round trip to Cathedral Lake
- Fish Species: Cutthroat trout, brook trout
- Highlights: Smaller than Ship Island but equally stunning, Cathedral Lake sits at 8,400 feet beneath Cathedral Rock. It’s home to feisty cutthroat and brook trout, with fish averaging 8–12 inches. The clear water makes sight fishing possible, and terrestrials (ants, hoppers) work well along the grassy shores.
- Why It’s Great: A shorter hike than Ship Island, with solitude and eager fish. The surrounding granite spires add a dramatic backdrop.
- Access Tip: Same trailhead as Ship Island; it’s a good day trip or overnight option.
- Yellowjacket Lake
- Location: Central wilderness, near Yellow Jacket Ranger Station
- Distance: 18.9 miles round trip
- Fish Species: Rainbow trout, cutthroat trout
- Highlights: Nestled in a meadowed basin with a waterfall feeding it, Yellowjacket Lake is a scenic spot with a solid population of rainbow and cutthroat trout. Fish here can reach 12–16 inches, feeding on midges and mayflies. The lake’s remoteness keeps pressure low, making for a rewarding experience.
- Why It’s Great: Less trafficked than the Crags lakes, offering a true wilderness feel. The trail’s wildflower meadows and creek crossings add to the journey.
- Access Tip: Long hike in (9+ miles one way), so plan for a multi-day trip; late summer avoids muddy trails.
- Horseshoe Lake (Loon Creek Area)
- Location: Western wilderness, along Loon Creek
- Distance: 19.2 miles round trip
- Fish Species: Cutthroat trout, brook trout
- Highlights: Reached via the Loon Creek trail, Horseshoe Lake is a quiet, forested lake with healthy cutthroat and brook trout populations. Fish average 10–14 inches and respond well to small nymphs and dry flies like parachutes or Royal Wulffs. Nearby hot springs add a bonus for post-fishing relaxation.
- Why It’s Great: Combines fishing with a soak in natural hot springs, plus a chance to spot wildlife like wolves or elk.
- Access Tip: Start at Loon Creek Guard Station; it’s a strenuous trek, best as a 2–3 day trip.
- Mirror Lake (Bighorn Crags)
- Location: Part of the Bighorn Crags lake network
- Distance: ~10–12 miles round trip (varies by route)
- Fish Species: Cutthroat trout, rainbow trout
- Highlights: Tucked between towering peaks, Mirror Lake lives up to its name with crystal-clear water reflecting the rugged landscape. It’s stocked with cutthroat and rainbow trout, averaging 8–12 inches, though larger fish lurk in deeper sections. Dry-dropper rigs (e.g., a hopper with a pheasant tail nymph) can be deadly here.
- Why It’s Great: Photogenic and fish-filled, with nearby lakes like Birdbill for variety. Ideal for a multi-day Crags adventure.
- Access Tip: Accessible via the same trail system as Ship Island and Cathedral; extend your trip to hit multiple lakes.
- Langer Lake
- Location: Near Ruffneck Peak, central wilderness
- Distance: 4.1 miles round trip
- Fish Species: Brook trout, cutthroat trout
- Highlights: A smaller, easier-to-reach lake, Langer sits at 8,600 feet near a fire lookout tower. It’s stocked with brook and cutthroat trout, typically 8–10 inches, that hit small flies like blue-winged olives or woolly buggers. The short hike makes it a great day-trip option.
- Why It’s Great: Quick access to high-country fishing, with bonus views from Ruffneck Peak.
- Access Tip: Trailhead near Hood Ranch airstrip; manageable as a day hike or overnight.
Why These Lakes Stand Out
The Frank Church’s lakes offer a rare blend of solitude and quality fishing. The Bighorn Crags trio (Ship Island, Cathedral, Mirror) are standouts for their scenery and trout, while Yellowjacket and Horseshoe add seclusion and unique features like waterfalls or hot springs.

With no roads or crowds, you’re fishing waters that feel as wild as they did centuries ago—perfect for anglers seeking adventure and a bent rod in Idaho’s untamed heart
