Overview

Mallard Marsh Campground is located along the reed-lined shores of Hosmer Lake a popular destination for fly-fishing, paddling and birding.

Recreation

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.

Facilities

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.

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.
