Portland Arch Nature Preserve’s South Trail is a compact woodland hike built around the area’s natural limestone arch—great for layered greenery, textured rock, and creek/low-spot water views. Best light is sunrise to mid-morning (soft filtered sun) or late afternoon; weekdays reduce crowding. Day-use only—confirm current hours/entry rules at the trailhead. Parking is along W Scout Camp Rd near the entrance.
