This campground is on a river bed called Mallard Marsh that leads into Hosmer Lake. Commonly referred to as the Hosmer Lake Campgrounds, South and neighboring Mallard Marsh each have a loyal following of campers who return every year. Mallard March Campground provides opportunities for fly-fishing as well as access to trails for hiking and horseback riding.

Natural Features:

Hosmer Lake is a hidden jewel of green and blue surrounded by dark green forest. Thickets of bulrush wands hide the most secretive wildlife and fish. At the north end, water drains into a porous rim of lava. The best way to experience this lake is by canoe, but a shoreline hike will still produce wondrous sights and sounds, and be sure to bring your camera to capture the spectacular view of Mt. Bachelor.

Hosmer is a “fly fishing only” lake well known for its breath taking views of Mt. Bachelor, South Sisters, Broken Top as well as wildlife viewing and the big Atlantic salmon, brook trout and rainbows that are quite visible in this shallow clear lake. Hosmer Lake is also a very popular lake for canoeists because of the beautiful surroundings, the abundant wildlife, waterfowl and easily seen large fish swimming around.
