When you come down the end of the Plym valley, carry on through Saltram, turn left for Plymstock (at this point you may be better crossing over to the cycle path)
Turn right at the big
Morrisons roundabout on the A379
At the mini roundabout outside the store take 3rd exit for Oreston Road
Follow until you see Plymstock road. Go all the way along to Deans Cross traffic lights.
Turn right
Keep on this road to Hooe
Take the left into Jennycliff Lane
Up to Staddon heights
Staddiscombe village
Turn right at the end
Next right to Heybrook Bay.
This route is a bit more interesting than suburban Plymstock, and you get a view just like this...
And a cafe.
