The Lake Wilderness Arboretum Foundation(LWAF) is a nonprofit organization that serves as steward for Lake Wilderness Arboretum.  The Foundation’s ongoing maintenance and improvements to forested areas, trails, display gardens and plant collections help provide a setting where visitors can enjoy and study both natural and cultivated landscapes in an otherwise urban area. As part of our stewardship, the Foundation also supports horticultural science and conservation by providing educational opportunities in those areas. Our Mission is “Building a sanctuary to inspire, educate and connect us to the natural world.”

The Arboretum can be found by a short drive within Maple Valley along side Lake Wilderness Park at 22520 SE 248th in Maple Valley, WA. Please view our Directions page for further instructions.
