Nolte State Park, State park near Cumberland, United States.

Nolte State Park is a Washington state park in King County, built around Deep Lake near the Green River Gorge. The grounds offer forested hiking trails, a fishing pier, a sandy beach, and a small boat launch for those who want to get out on the water.

The land was a resort for many years before Minnie Nolte donated it to the state of Washington in 1971, creating the 117-acre park. It has since remained under state management as a public recreation area.

The park's land was a resort for many years before Minnie Nolte donated it to the state in 1971, and the lake still draws anglers after rainbow trout, coastal cutthroat trout, kokanee, crappie and brown bullhead. A public fishing pier and a beach area serve visitors, and a hiking trail circles Deep Lake.

Arriving by car requires a valid state recreation pass, but those on foot or by bicycle can enter at no cost. Most trails are well-kept and easy to walk, making the park a good option for visitors of all ages.

Deep Lake covers 39 acres but reaches 76 feet deep, and its water holds rainbow trout, coastal cutthroat trout, kokanee, crappie and brown bullhead. Anglers fish from a public pier, and boats can only be carried in, with limited parking at the launch.
