In the agency’s own words

Located WITHIN OREGON on Hosmer Lake, South Campground provides visitors with access to flyfishing, paddling and hiking. Keep reading

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.

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. There is also a boat ramp that provides access to Hosmer Lake. Boat launch parking is for day use only and requires a recreation fee separate from camping fees.

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.

Charges & Cancellations

Once your reservation start date has begun, neither the Recreation.gov Contact Center nor the campground manager will be able to modify your reservation.

What the agency tells you

Everything else this campground posts · 5
Rule

Reserved Sites will be held until check out time (NOON) the day following your arrival date. Sites must be occupied by the checkout time of that following day to hold a reservation or the site will be forfeited and released to other guests. Once your reservation start date has begun, neither the Recreation.gov Contact Center nor the campground manager will be able to modify your reservation.

Rule

Refunds: Refund requests made through www.recreation.gov will be charged a $10 processing fee. This fee is retained by the reservation service contractor along with the non-refundable reservation fee. All requests for the return of the non-refundable reservation fee and the cancellation fee will be declined by the campground concessionaire as they did not receive these fees (these are the fees retained by the reservation contractor, a different entity).

Rule

Don't Move Firewood: Please protect Pacific Northwest forests by preventing the spread of invasive species. Firewood can carry insects and diseases that can threaten the health of our western forests. You can make a difference by obtaining and burning your firewood near your camping destination. Visit Dontmovefirewood.org for further information.

Rule

Camping or otherwise occupying a single location (including leaving camping equipment and/or related supplies) for a period longer than 14 consecutive calendar days is prohibited. ‘Location’ means the occupied area, the occupied campsite, and the National Forest System lands in the immediate vicinity thereof. Camping or occupying any location on all National Forest lands for more than 28 calendar days total during a calendar year is prohibited.

Rule

NO generator use is allowed in campgrounds between 10:00PM and 7:00AM (36 CFR 261.10). Silent power banks or battery powered devices are allowed.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

How we know

every fact on this page, and where it came from
Right now: U.S. Forest Service’s own recreation database flags it not open and publishes no reason and no date. That’s a flag, not a notice: the number below is the only way to be sure.
Cell signal: the Forest Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
