About
Overview

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.
Nearby Attractions
Visitors enjoy traveling the Cascade Lakes Scenic Byway which climbs 66-miles through the Cascade Range, weaving past snow-capped peaks and alpine lakes.

Is MALLARD MARSH CAMPGROUND fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
