Redfish Lake

Sockeye salmon once returned to the Sawtooth Valley in enormous numbers, with estimates of well over a hundred thousand fish in a good year. Their long journey from the Pacific was among the highest and longest salmon migrations on earth, and the Shoshone-Bannock people have relied on and honored these fish for countless generations, a cultural legacy they still uphold today.

Commercial fishing, logging, pollution, and above all a series of dams on the lower Snake River collapsed the run. By the early 1990s the returns had fallen to almost nothing. In 1992 a single male sockeye made it all the way back to Redfish Lake, and he was nicknamed Lonesome Larry, a lonely symbol of how close the run had come to disappearing.

Larry's return, and the warnings the Shoshone-Bannock Tribes had long been raising, helped launch a captive-breeding rescue that pools the work of the tribes, federal agencies, and Idaho Fish and Game. Sockeye now return to the Sawtooth Valley again in larger numbers, still fragile but alive, and standing on the shore where they spawn is standing inside that recovery.

The Sawtooths are built of pale granite that cooled underground tens of millions of years ago and was later lifted and exposed. During the Ice Age, glaciers ground down out of these peaks and gouged the basin that Redfish Lake now fills, leaving behind the ridge of rock and gravel, a moraine, that dams the lake at its lower end.

That glacial history is why the water is so clear and cold and why the shoreline has those unusual sandy beaches, made of granite ground to grit. Mount Heyburn and the other spires above the lake are the same story in reverse, the hard rock the glaciers could not carry away.

Beyond the famous salmon, the lake and the forest around it hold rainbow and other trout, osprey and bald eagles fishing the surface, and the occasional black bear moving through the huckleberry brush. Mule deer and, higher up, mountain goats live in the surrounding Sawtooths.

The forest is classic high Idaho: lodgepole pine, Douglas fir, and Engelmann spruce, with wildflower meadows opening up as the trails climb. In the still of early morning the peaks lay a perfect mirror across the lake, one of the reasons this spot has been photographed for a century.

Summer is the season here. The road, the lodge, and the boat shuttle open once the snow clears, usually by early summer, and the beaches and trails stay busy through the warm months. Wildflowers peak in mid to late summer up in the high basins.

Autumn brings gold to the aspens and quiet to the shoreline, but the weather turns early at this elevation. Winter buries the area in deep snow and the road is not maintained, so the lake belongs to skiers and the cold. Even at the height of summer, pack a warm layer for the evenings.

Redfish Lake, in the Sawtooth National Recreation Area of central Idaho near Stanley, is a stunningly beautiful alpine lake set beneath the jagged peaks of the Sawtooth Mountains, one of the most photographed and beloved spots in the state. The clear blue lake, ringed by pine forests and framed by the dramatic mountains reflected in its waters, offers swimming, boating, paddling, fishing, and beaches, along with a historic lodge, campgrounds, and trailheads into the wilderness. Named for the sockeye salmon that once filled it, it is a gem of the Sawtooths. With its clear alpine waters and mountain scenery, Redfish Lake offers a spectacular destination in Idaho.

You can swim at the beaches, boat, kayak, paddle, and fish on the clear alpine lake, relax at the historic lodge, camp at the campgrounds, hike trails into the Sawtooth Wilderness from the lake, take a boat shuttle across the water to trailheads, and soak in the spectacular mountain scenery reflected in the lake. The beaches, the boating, and the mountain views are highlights, and the lake is a gateway to wilderness hiking. With its swimming, boating, fishing, and stunning Sawtooth scenery, Redfish Lake offers a rewarding outdoor experience in central Idaho.

The alpine lake water is cold even in summer, so swimmers should be cautious of the cold and watch children closely, while boaters and paddlers should wear life jackets and watch for winds and afternoon storms that can arise quickly in the mountains. The high elevation brings strong sun and thin air, so bring sun protection and water. On trails, it is bear country, so take precautions. Being mindful of the cold water, mountain weather, and elevation ensures a safe visit to Redfish Lake in central Idaho.

Summer through early fall is the prime time for swimming, boating, and enjoying the lake, when the weather is warmest and the lodge, beaches, and campgrounds are open, though even summer nights are cold at the elevation, while fall brings golden color and fewer crowds. The lake and roads may be snowbound in winter. Summer is the busy, beautiful peak season. For warm-weather lake recreation aim for summer, and for fall color and quiet, early autumn, at Redfish Lake in the Sawtooths of central Idaho.

Redfish Lake is in the Sawtooth National Recreation Area of central Idaho near Stanley, within reach of the Sawtooth Wilderness and White Cloud Peaks, the Salmon River with Sunbeam Hot Springs, the Galena Summit overlook, and Sun Valley. That makes Redfish Lake a spectacular stop to combine with the Sawtooth National Recreation Area, the Salmon River, and the other attractions of central Idaho on a visit to the state.
