From Bend, travel 35.5 miles southwest on Cascade Lakes Hwy (46), then 1.3 miles east on Forest Road 4625. South Campground will come up on the right side first and then Mallard Marsh.
Mallard Marsh Campground is located along the reed-lined shores of Hosmer Lake a popular destination for fly-fishing, paddling and birding.
Nearby Hosmer Lake offers opportunities for fly fishing and boating as well as spectacular views. There are also trails and other opportunities for hiking and horseback riding nearby.
This facility has vault toilets and each site is equipped with a picnic table and fire pit with grill. Please note campers will need to bring their own water supply.
At the north end of Hosmer Lake, water drains into a porous rim of lava. 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. The best way to experience this lake is by canoe or kayak as shore access is limited due to marshy vegetation.
Visitors enjoy traveling the Cascade Lakes Scenic Byway which climbs 66-miles through the Cascade Range, weaving past snow-capped peaks and alpine lakes.
