CLOSED for 2021 season.

There's something disturbing in the woods of Sammamish.

Every year at the end of October a fearsome shadow falls over Beaver Lake Park. A group of demented, dedicated volunteers crawl out to assemble an event that will leave you screaming. Nightmare At Beaver Lake is the Seattle area’s largest indoor/outdoor haunted house.

Fear follows as you wind through a trail of terror nearly a mile long that leads you to a dreadful haunted house..

Nightmare at Beaver Lake is a 3/4 of a mile long hike through the woods of Beaver Lake park. It can be cold. It can be muddy in places.
