Emerald Valley Arboretum is hosting guided Tree Walks on Saturday, June 13 at 10 AM and 2 PM. The walks are about 30 minutes long and give visitors a chance to learn about the historic trees and plant life found across the 12-acre property. The arboretum is home to more than 60 species of trees and woody plants, many over 100 years old, plus an 1840s farmhouse overlooking a wooded ravine trail.
