About Lost Lake Nature Park

Lost Lake Nature Park is a tranquil natural area in Sammamish, Washington, offering serene forested landscapes, a peaceful lake, and a network of trails perfect for outdoor enthusiasts seeking easy hiking, wildlife viewing, and seasonal activities.

Wilderness Landscape & Natural Heritage

Lost Lake Nature Park is a popular 175-acre natural reserve located in Sammamish, Washington, just east of Seattle. The park is centered around Lost Lake, a small but scenic body of water that is replenished primarily by underground springs, resulting in clear, cool waters. The surrounding landscape features mixed Douglas fir and western red cedar forests, wetlands, and open meadows, providing a diverse habitat for wildlife such as great blue herons, beavers, and a variety of songbirds. Originally part of the indigenous land of the Snoqualmie people, the park is now managed by the City of Sammamish, with an emphasis on passive recreation and habitat protection. Visitors can explore approximately 4.5 miles of well-maintained trails that range from easy to moderate difficulty, making it suitable for families, walkers, and nature photographers. Notable landmarks include the Lost Lake Wetland area, observation platforms for bird watching, and interpretive signs that educate visitors about the local flora, fauna, and geology. The park is especially popular during spring and fall migrations for birdwatching and is also used for community events such as guided nature walks. Lost Lake Nature Park offers a peaceful retreat close to urban areas, blending opportunities for recreation with environmental education and conservation efforts. It remains a favorite spot for casual day hikes, fishing from designated banks, and winter snowshoeing when conditions allow.
