The Mt. Hood National Forest will reopen most developed day-use and trailhead sites to recreational users this Friday (May 29).  Forest officials say several sites will not open immediately, including most campgrounds.  These sites will open slowly as they are assessed for public and employee safety.  Recreation managers are coordinating with campground concessionaires, completing spring maintenance, and training seasonal staff in preparation for opening sites.  Some facilities, such as vault bathrooms, may not be maintained daily.  Forest officials recommend that all visitors be prepared to provide for their own sanitation and be as self-contained as possible while recreating.  A complete list of open and closed recreation sites will be on the Mt. Hood National Forest website.
