The Heart of the Sawtooth National Recreation Area
Redfish Lake is the centerpiece of the Sawtooth National Recreation Area and the busiest, most beloved destination in central Idaho's high country. Five miles south of Stanley off Highway 75, this glacial lake stretches toward the jagged Sawtooth crest, with Mount Heyburn and the Grand Mogul rising straight from its far shore. It is named for the sockeye salmon that once turned the inlet red on their epic run from the Pacific. Today it is the launch point for some of Idaho's finest hikes plus a full slate of on-the-water fun, which makes it the natural base camp for a Sawtooth trip.
Hike the Bench Lakes Trail
The standout day hike from the lake is the Bench Lakes Trail. Starting near the Redfish Lake Lodge area, it climbs gradually through forest with growing views back over the lake before reaching a stair-step series of small alpine lakes tucked beneath the Grand Mogul. The lower Bench Lakes make a great moderate outing of about 7 to 8 miles round trip, while strong hikers can push to the upper lakes for solitude and bigger scenery. It is one of the best effort-to-reward hikes in the range and a perfect introduction to Sawtooth lake basins. Other options from the lakeshore include the easy Fishhook Creek Trail to a beaver-pond meadow and the longer routes toward Alpine Lake and the Sawtooth interior.
Take the Boat Shuttle Into the Backcountry
One of the best things to do at Redfish Lake is also the most uniquely convenient: Redfish Lake Lodge runs a boat shuttle across the lake to the Inlet Transfer Camp on the far southwest shore. This skips a flat, less interesting 5-mile lakeshore walk and drops you straight at the trailheads for the Sawtooth backcountry. From the inlet you can:
- Day hike toward Alpine Lake and the high lakes beyond.
- Start a backpacking trip into the Cramer Lakes or over toward the interior basins.
- Simply ride across for the views and walk a short loop near the inlet.
Check the lodge for the current shuttle schedule and fares, and buy a return ticket so you are not stranded if you misjudge your pace. The boat is hugely popular in summer, so reserve or arrive early.
Swim, Paddle, and Fish
Redfish Lake is just as much a water destination as a trailhead. The sandy swimming beach near the lodge warms up enough for a refreshing dip on hot August afternoons, and it is ideal for families. You can rent kayaks, paddleboards, and small boats at the marina, or bring your own to paddle the quieter southern shoreline beneath the peaks. Anglers fish for trout and kokanee, and the visitor center near the entrance offers ranger talks and exhibits on the lake's salmon history.

Where to Stay at Redfish Lake
You have two main ways to stay right at the water:
- Redfish Lake Lodge, a historic property with cabins, lodge rooms, a restaurant, and the marina; it books out months ahead for summer, so plan early.
- Forest Service campgrounds around the lake, including Redfish Outlet, Glacier View, and Point, many of which take reservations and fill fast on weekends.
If everything is full, Stanley is only minutes away with motels and more campgrounds, and it has the added bonus of nearby hot springs along the Salmon River and Highway 75.
Best Time to Go and Practical Tips
The lake comes alive from July through September. July and August offer the warmest water and full shuttle service but the biggest crowds, while September brings cooler air, thinner crowds, and the first hints of fall color in the surrounding willows. A few things to know before you go:
- There is a day-use fee for the Redfish area, and parking near the lodge and trailheads fills early on summer weekends.
- Cell service is spotty; download maps and the shuttle schedule in advance.
- Afternoon thunderstorms are common in midsummer, so start hikes early.
- Bring layers, sun protection, and bug spray, especially in July.
Whether you come for a single big hike, a lazy beach day, or a launch into the Sawtooth Wilderness, Redfish Lake delivers the full central Idaho experience in one stunning spot.
The Salmon Story Behind the Name
Redfish Lake earns its name from one of the most remarkable wildlife journeys in North America. Sockeye salmon are born here, swim more than 900 miles down the Salmon, Snake, and Columbia rivers to the Pacific Ocean, and then, against staggering odds, climb back up through eight major dams and roughly 6,500 feet of elevation gain to spawn in the same lake. When they returned in huge numbers, their bright red spawning bodies turned the lake's inlet crimson, which is how it got the name. The run nearly vanished in the twentieth century, and a hatchery and recovery program has fought to keep these Snake River sockeye from extinction. Stop by the visitor center to learn the full story; it adds real depth to a swim or a hike here.
Make a Full Day or Weekend of It
Because Redfish Lake combines easy water access with serious trailheads, it rewards a flexible itinerary. A great single day might pair a morning Bench Lakes hike with an afternoon on the beach and a paddle before the wind picks up. A weekend lets you add the boat shuttle into the backcountry on day two and an early Fishhook Creek stroll on day three. Families often anchor at the swimming beach and rotate in short hikes, while backpackers use the lake purely as a springboard into the wilderness. However you structure it, build in time to simply sit on the shore at golden hour, when the Sawtooth crest lights up and reflects across the water.
