Located just outside the city of Yakima, this arboretum showcases hundreds of different plant species through display gardens and themed areas.
The arboretum is located between the Yakima River and Interstate 82 and contains a multitude of different tree collections, most of which are labelled so visitors can learn as they walk along. In addition to the cultivated gardens, there is also a large natural area along the river and several ponds and wetlands sprinkled throughout the grounds.
The arboretum is also easily accessible from the Yakima Greenway trail, which is a paved trail along the Yakima and Naches rivers.
