Tunnel Mill offers mossy limestone ruins, a narrow stone tunnel/arch, millrace and wooded banks — excellent for moody, textural shots and long exposures of flowing water. Best light is early morning or late afternoon; autumn and after rain give saturated tones and higher water flow. Small pull-off parking on Tunnel Mill Rd; short walk over uneven ground and stairs—wear sturdy shoes. No entry fee; respect private boundaries. Weekdays are quieter. Bring polarizer for reflections.
