Managed by the Bureau of Land Management, Hollenbeck Park sits just outside Trout Lake in Washington's Mt. Adams corridor, accessible by both vehicle and boat. Electric hookups and drinking water are available at every site, along with picnic tables, trash service, and cell coverage. A small creek runs through the area, with a swimming hole nearby. Porta-potties serve the sites. Anglers and families tend to return annually, drawn by open sightlines toward Mt. Adams. Summer weekends fill quickly, so arriving early in the week gives more flexibility.
