Starting at the layby on Beacon Road, there is another alternative car park at (12) which offers to complete the walk in reverse; however, not recommended as the last section would be all hill from (6) to (3). The car park at (12) is run by the National Trust, which charges.
The layby on Beacon Road is popular and can fill early. Alternate parking is near the cafe.
(S/E) From the layby, cross the road and take the track opposite (southeast) and keep left at the two upcoming forks.
(1) At this point, turn right south up toward (2) the trig point and the far-reaching views (dependent on the weather).
Note: Although called a trig point, due to its shape, it is not. It is a more modern GPS datum point.
(2) From the Beacon, Trig Point, head left east on the designated path towards the fields and then a more substantial track, past a shelter which houses a metal case. (This has something to do with the nearby water storage reservoir.) Continue on down to meet the road.
(3) Turn right and south, then turn left next to the old barn. This appears to be a private drive to premises, but is a permitted footpath. Continue down the path/track. The path leads behind houses to where it meets the housing estate road.
(4) Head left northwest and down Polbreen Lane. Continue down the lane to the main St Agnes Road (B3277), turn left (north). Walk down through the town (public convenience on the left hand side) to the church.
(5) Having passed the church and on the opposite side of the road, see the end of terraced houses called 'Strippy Strappy'. Walk down the hill beside the terrace, bearing left on the way down, meeting 'Quay Road' at the bottom. Turn left and continue walking down the hill, near to the bottom (public convenience on the right). Note the car park. Continue down to view the beach and harbour of Trevaunance Cove.
(6) Turn around and walk back. The route now picks up a section of the South West Coastal Path, heading in a northwest direction. There are numerous 'shortcuts' onto the path. Anything further up than the car park is the last turn to the path. Continue along the road, turning to track. Note: This level area formed part of the old docks.
Note: The Southwest Coast Path follows the coastline around the southwest peninsula of the UK. This section follows a defined route which should be followed. There are sections with shear drops; keeping everyone aware is important. Enjoy the views, but not too close. There are also some disused mine workings, mine buildings. Keep to the designated footpaths.
(7) Follow the coastal path.
(8) St Agnes Head. The views may be great, but be mindful of the sheer drops; rock is slippery when wet. Continuing along the coastal path, which also follows farm field hedges. At the end of the field systems. Many more paths and routes will appear approaching the old mine working buildings.
Approaching (9), the path opens up, and keeping to the higher left side avoids the nearer path to the headland.
(9) Wheal Coates, mine working, (option at (9) turning left east 400m to (12) to shorten the route). Walk down through the old mine workings, see the old mine engine house on the cliff, coastal path. (This is one of the most picturesque images of an old mine and Cornish coastline.)
(10) From the old mine workings, continue on the coast path to the small rocky outcrop (optional, turn left east and go to (12)).
(11) Looking over Chapel Porth, when the tide is out (usually on spring tides) remnants of a shipwreck and the engine's boiler can be seen. Continue, leaving the coastal path, and go to (12). From (11), there are several paths up and back to the road (Beacon Drive). This route follows the path up left, in a northwest direction up the gully.
(12) Meeting the road, Beacon Drive, continue in a northwest direction passing campsites, roadside stalls, and a small cafe on the left to the layby and the start.
