Hoyt Arboretum Professional Review and Guide
"This route travels through the spectacular 185-acre tree museum of Hoyt Arboretum in Southwest Portland. The path winds through a variety of forested ecosystems, including oak woodland, redwoods, and ponderosa pine forest. Hoyt Arboretum was founded in 1928, and the first trees were planted in the 1930s.
The arboretum has more than 5,000 labeled plants and trees that represent more than 1,100 different species. Before you start the hike be sure to stop in the visitor center (open 9:00 A.M. to 4:00 P.M. daily). This loop route takes you past several groups of tree species that are grouped by family. You’ll start off on the Oak Trail, which takes you through a sunny oak woodland filled with black oak, Japanese evergreen oak, and Konara oak."
