About
Discover the Pacific Northwest's oldest arboretum, a captivating outdoor laboratory rich in history and towering trees. Part of the larger Wind River Experimental Forest, this unique research arboretum in Carson, Washington, blends scientific heritage with natural beauty, offering visitors an immersive educational experience amidst a diverse collection of trees.
Established in 1912, the arboretum was designed to compare the performance of native Pacific Northwest tree species with exotic varieties from around the globe, providing invaluable insights into sustainable forestry. Today, visitors can explore a fascinating landscape where colossal native old-growth trees stand alongside the surviving remnants of experimental plantings. The interpretive trails showcase impressive specimens like Coast Douglas-fir, Western Hemlock, and the famous section of the Mineral Tree—once the tallest Douglas-fir in the state—alongside non-native species such as the distinctive Monkey Puzzle Trees and Giant Sequoias.
A visit to the Wind River Arboretum is an opportunity to connect with over a century of forest research, stroll through serene woodland, and marvel at the enduring power and beauty of the region's arboreal giants. It's a memorable destination for anyone interested in botany, history, or simply a peaceful walk surrounded by some of the most magnificent trees in Washington. The ongoing restoration efforts are bringing this historic site back to its original prominence, ensuring its legacy continues for future generations.

The Wind River Arboretum was established in 1912 by Thornton T. Munger of the United States Forest Service, making it the oldest arboretum in the Pacific Northwest. Its primary purpose was to conduct extensive research, comparing tree species from various temperate and subtropical zones worldwide with native Pacific Northwest trees to determine their suitability for commercial forestry. Over 90 years, 165 species were tested, leading to the conclusion that native species like Coast Douglas-fir and Western Hemlock were best adapted to the local environment, with many non-native species failing to thrive long-term. The arboretum was an integral part of the broader Wind River Experimental Forest, formally designated in 1932, which played a crucial role in early forest research, including nursery practices and silvicultural studies. After decades of reduced maintenance, the arboretum is now undergoing restoration by the Wind River Trust and volunteers, aiming to preserve its historic plantings and enhance visitor experience.
What to do here
Take an interpretive walk, identify different tree species using trail markers, enjoy a picnic at nearby Hemlock Picnic Area, or combine your visit with other activities within the Wind River Historic District, such as the accessible Whistle Punk Trail.
Seasonal info
In winter, expect potential snow and rain, with deciduous trees bare and evergreens covered in moss and lichen, creating a unique photographic opportunity. Summer brings warmer weather and lower water levels in Trout Creek, ideal for wading.
Accessibility
The interpretive walk generally has little elevation gain and is maintained to be wide and clear, making it suitable for a pleasant, easy walk. The nearby Whistle Punk Trail in the wider Wind River Historic District is also accessible.
