COVID-19 update:

The Lake Wilderness Arboretum is open to the public during daylight hours. Some of the parking lots owned by the City of Maple Valley may be closed. Please use your best judgement and keep appropriate social distancing if you decide to walk through the gardens.

We have some minimal staff on site doing essential maintenance to preserve the arboretum. 

The 2020 LW Arboretum Spring Plant Sale has been canceled due to shelter-in-place rules. Our Fall Plant Sale in September will modified to include vendors and more plants. Thank you for your support!

The Lake Wilderness Arboretum is teaming up with the Lake Wilderness Lodge to offer a number of fantastic venues to hold your special event. If you are interested in learning more, please contact the lodge.
