Lake Wilderness Arboretum is a 42-acres oasis of native forest, cultivated gardens and botanical collections situated in the heart of the bustling city of Maple Valley, Washington.
Five display gardens boast collections of plants and flowers that our volunteers have nurtured and maintained for 50 years. From the Smith-Mossman Western Azalea Garden to the Legacy Garden to the Woodland Garden, visitors are welcome to meander appreciatively through beautiful examples of thriving northwest landscapes and visit the Arboretum’s Little Free Library, too!
Stroll through the Tribal Life Trail and enjoy a horticultural education about the ways Native Americans used natural resources for everyday living. This beautiful trail is maintained by Washington State Master Gardeners.
Be sure to visit the 26 acres of second-growth forest, a relaxing retreat from everyday life. Walk the forest trails which transport you to Nature’s quiet world of beauty.
Lake Wilderness Arboretum is located in Lake Wilderness Park at 22520 SE 248th in Maple Valley, WA.
