Lake Wilderness Arboretum

Lake Wilderness Arboretum is a botanical garden spread across multiple acres with forested pathways, planted gardens, and collections of trees and shrubs native to the Pacific Northwest region. The layout guides visitors through different zones where regional plants grow in organized but natural-looking arrangements.

The arboretum was established in 1965 as a public garden focused on the south King County area. Management passed to the City of Maple Valley in 2003, bringing changes to how the space is maintained and developed.

The space hosts educational programs and guided walks that help visitors learn about the plants and trees found naturally across the region. These activities bring together families and nature enthusiasts who come to understand the local environment better.

The garden is open daily from sunrise to sunset with free entry and parking near the main entrance. Wear sturdy shoes for walking the trails, as wooded paths can be muddy or slippery depending on recent weather.

The arboretum holds one of the world's largest collections of Western Azaleas, with over 200 different varieties that bloom in spring. This specialized collection draws visitors who come specifically to see the colorful flowering display during the growing season.
