Breitenbush Lake campground is located on the Warm Springs Indian Reservation and is governed by their rules and laws. The campground is located on the shores of Breitenbush Lake and is fairly difficult to reach due to deteriorated access roads.
The Breitenbush Lake campground sees very little use and you will likely be the only person there depending on the time of year you visit. As such there are also very little amenities and you must bring your own drinking water and pack out your own trash.
Fishing, swimming, wading, and boating in Breitenbush lake is prohibited unless you have a special permit. Dogs must be leashed at all times and are not allowed in the lake. According to a rules and regulations sign posted on site ANY activity performed outside of the bounds of the campground is considered criminal trespass.
Overall the campground is beautiful however due to over-regulation by the Warm Springs Indian Reservation we see little reason to visit here. About the only time it would make sense is if you are spending the night prior to heading out the Pacific Crest Trail or into nearby Jefferson Park. Otherwise the rules state you can literally do nothing but sit in your campsite else risk prosecution due to “criminal trespass”. For a full list of rules and regulations see the photos below.
