About Mallard Marsh Campground
Overview

Facilities

Natural Features
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.
