Hosmer Lake is a peaceful, blue-green oasis tucked away in Oregon's Cascade Mountains, about 39 miles west of Bend in the Deschutes National Forest. Resting at 4,964 feet, this shallow lake covers around 198 acres, with an average depth of 3 feet and a maximum depth of 12 feet. It's one of the most scenic and unique lakes in the region.

The first time I visited, I was struck by the calm water, surrounded by dark green forest and framed by views of Mount Bachelor, South Sister, and Broken Top. Hosmer Lake is just off the Cascade Lakes Scenic Byway, a route packed with stunning Oregon lakes.

Hosmer Lake was once called Mud Lake, but in 1962, it was renamed for Paul Hosmer, a local naturalist. Now, it's a top spot for fly fishing, paddling, and wildlife watching. With easy access and a cozy, wild feel, it's perfect for anyone who loves the outdoors.

Outdoor Activities at Hosmer Lake

Kayaking & Boating

Kayaking and canoeing are the best ways to see every corner of Hosmer Lake. The water is so clear you can spot fish swimming below your boat almost anywhere.

Only electric motors are allowed at Hosmer Lake, so there are no gas-powered boats, making it perfect for beginners or anyone who just wants to relax and float.

Canoeing and kayaking at Hosmer Lake is peaceful and easy. The water is usually calm, and the scenery is incredible. You can paddle through open blue channels, slip into green marshes filled with bulrush and lilies, and drift close to the shore where ducks and deer like to hide.

Fly Fishing

Hosmer Lake is a catch-and-release fly fishing spot. You can only use barbless hooks, and you must release any fish you catch. The lake is stocked with:

Atlantic salmon (up to 22 inches, most around 16 inches)
Brook trout (average 14 inches)
Rainbow trout (sometimes seen cruising the shallows)

Only electric motors or muscle-powered boats are allowed, so the lake stays quiet and calm. Bring your canoe or kayak for the best access.

Hiking & Wildlife Viewing

No boat? No problem. A walk along the shoreline is full of surprises. You might spot:

Bald eagles
Osprey
Red-winged blackbirds
Deer

The northern end of the lake is especially marshy and wild. I once watched an osprey dive for fish while I was eating lunch on a log. It's a great place for nature photography, so bring your camera!

Hosmer Lake in Winter

From October through May, the Cascade Lakes Scenic Byway is closed due to snow. Access is limited, and deep snow can block the road until June. In winter, the lake is quiet and frozen. It is a hidden winter wonderland for snowshoers or backcountry skiers willing to make the trek.

Camping at Hosmer Lake is for folks who like things simple and quiet. There are two campgrounds at the lake.

South Campground: $10 per night, open from late May to late September. No drinking water, but the views are the best, and you're right on the lake.

Mallard Marsh Campground: A bit more tucked away, with a boat launch trail between sites 14 and 15.

Both are managed by the U.S. Forest Service. You'll find vault toilets, picnic tables, and basic campsites. No hookups, no RVs, and no potable water, so bring what you need.

Looking for more comfort? Check out one of the Cascade Lakes resorts, or stay in Bend for hotels, motels, or vacation rentals.
