Just past the entrance to Coleton Fishacre National Trust house (beyond Brixham, along lanes) is a small NT car park (donations) from where there's a round walk through protected coastal areas then back through inland paths.(about 4 miles in all). The outward path first passes a tall stone structure which was a shipping guide. On reaching the actual coast path high on the cliffs, ahead are a jumble of brick buildings and explanatory notices about their war-time use. Now obscured by a good deal of vegetation it's a very atmospheric place. The path becomes quite narrow and in parts rather steep. The Coastwatch building is prominent there and we found that the 2 men on voluntary watch there were more than willing to talk to us about recent sightings of dolphins and basking sharks. They encouraged us to look through their telescopes at seals down by the rocks a long way below. The path passes through some areas of tall trees and some scrub; the flowers in the different areas are most interesting and the scrub was full of tiny birds. An extremely steep flight of steps takes one down to where there is access to a tiny beach and then there's a steep climb up again alongside a field absolutely yellow with primroses. On reaching a lane, the return path would be to the right, but turning left instead will take you into Kingswear with it's sub-tropical gardens and spectacular views across the River Dart to Dartmouth. There's a car and passenger ferry there. Returning to the top of the primrose field, continue along the lane until a sign points right, back towards Lower Brownstone Farm itself. Follow down then up (a rather wet gully for a path there) passing farm cottages then the main farm. The sign then points right back to the car park. We just thought this walk was so beautiful, all the way round with the bonus of being able to cross to Dartmouth too, so that we wanted others to enjoy it.
