Historically, mid-October is peak fall foliage season in Maine"s Acadia National Park. The forest canopy is aflame with autumn color, and here, the highbush blueberries on the forest floor provide an additional splash of color. Acadia has six marked coastal trails, and our photo today was taken on one of the most popular: Wonderland Trail. It’s just 1.4 miles round-trip, an easy trek for families and casual hikers. Acadia is Maine’s only national park, and it’s easy to see why this landscape was preserved—look at that beautiful fall color, and that’s just at ground level.
