Porcupine Mountains, MI
Link a path of glowing mushrooms.
Known as foxfire, bioluminescent fungi is found throughout temperate zones in wet, rotting bark. Scientists don’t know why some fungi glow and not others. One hypothesis: The glow attracts insects, and they spread the mushrooms’ spores. Bring a headlamp (with a red filter, if you have one, to preserve your night vision) and head north from the Pinkerton trailhead through old-growth conifers toward Lake Superior on Michigan’s Upper Peninsula. Look for soggy, downed trees on this 5.2-mile out-and-back, and agitate chunks of bark to oxidize the mushroom’s enzymes and reveal a light blue glow. (906) 885-5275; michigan.gov/dnr
