Washington’s Hidden River Fishing Hole — Undeveloped Riverside Access, Studhalter Fishing Hole, Coho Salmon & Rainbow Trout, Rocky Beach Picnicking Near Morton
Tilton River State Park is a small, undeveloped state park along the Tilton River near Morton, Lewis County, Washington. The park features the historic Studhalter Fishing Hole, coho salmon and stocked rainbow trout fishing, a short informal trail through forest to the river, a rocky riverside beach for picnicking, and a completely rustic experience with no developed facilities.
Tilton River State Park is one of Washington’s most hidden and rustic state properties — a tiny, undeveloped riverside access point along Highway 508 near milepost 27. The park is easily missed; a small, unmarked pull-off accommodates only a few vehicles. A short informal trail (roughly 0.25 to 1 mile) descends through forest to the Tilton River, where the Studhalter Fishing Hole has been a local favorite for decades. The river supports runs of hatchery coho salmon and is stocked with rainbow trout. A rocky beach along the river provides a scenic spot for picnicking, relaxing, and wading. Handmade fire pits dot the area. There are no restrooms, no signs, no maintained trails, and no staffing — this is a pure pack-in/pack-out wilderness experience.
