Lake Wilderness Arboretum (40 acres), known for a time as the South King County Arboretum, is an arboretum in Maple Valley, Washington.

The arboretum is open daily without charge. It is located off the Lake Wilderness Trail.

In addition to a focus on Northwest native plants, the Arboretum has one of the world's largest collections of the Western Azalea (Rhododendron occidentale), with over 200 selections of the species.
The Lake Wilderness Arboretum is managed by the Lake Wilderness Arboretum Foundation, a 501(c)3 non-profit organization. The arboretum was first established as a nonprofit organization in 1965, with its initial design completed and implemented in 1970. The Western Azalea Garden was dedicated in June 2000. The recently incorporated City of Maple Valley finalized the transfer of Lake Wilderness Park and the Arboretum from King County in January 2003. In April 2003, the name was changed from the original name, South King County Arboretum, to Lake Wilderness Arboretum. The name of the Arboretum Foundation was changed to Lake Wilderness Arboretum Foundation (LWAF) in 2007.

  • Great walking trails. Bring bug spray! Lots of mosquitoes. Lots of Maple Valley Rocks painted and hidden throughout the arboretum. Beautiful paths to walk, a pond, lots of flowers and millions if plants, child's play areas, a little library, totem poles, nature, bunnies play and birds forage and sing. Disc golf course too. Beautiful area.
  • The Lake Wilderness Arboretum in Maple Valley WA is a hidden gem. It features irises, rhododendron, roses, and so many more plants. The arboretum is often overlooked because Lake Wilderness also features a lake and playground. If you are looking for a local arboretum with a small town feel, this is hard to beat.
