Take the Mormon Trail up South Mountain until you see signs for Hidden Valley, you can take the Hidden Valley trail to Fat Man’s Pass and back, or connect to the National Trail to make a full loop back to the Mormon Trail. Keep an eye out for petroglyphs along the hike. #hiking #mountains #petroglyphys #nature #geology #outdoors #fitness
