The Spring Grove Cemetery and Arboretum is a US National Historic Landmark. Within its expansive 750 acres lie historic burial grounds, memorials, and an arboretum. Spring (March, April, and May) and fall (September, October, and November) are often considered the best times to visit. During March, April, and May, you can see the beautiful blooms of cherry blossoms and other flowering trees throughout the grounds. Many birds can be seen around the lakes as well. In September, October, and November, waves of color erupt throughout the arboretum as the leaves change. Hues of amber and gold can be spotted earlier in the season, which later develop into shades of scarlet and crimson as temperatures continue to drop. The trees at the arboretum usually reach peak colors in mid to late October.
