Agios Ioannis, Crete

Right, as you've probably already guessed, the above photo is not the Agios Ioannis light - let me explain!
We were staying in Plakias on the south coast of Crete in the Rethymnon prefecture. The rest of the party were visiting Rethymno, which I had done the year before, so I asked if I could take the car and round up a few lighthouses. I was told yes with the proviso (on account of my antisocial behaviour) that I left around the same time as everyone else and I was to be back in Plakias by around 3.30pm when the others were due back.
Consequently I left Plakias around 9.40, drove to Rethymno, then Heraklion, then headed for Agios Ioannis. Delayed through Quad Bike City aka Malia, I realised that by this stage, I would be hard pushed to do this lighthouse and the three in Heraklion.
Still I decided to press on. There seemed to be a road branching off from Neapoli heading towards Elounta, which I intended to take. However, the only signpost was for Neapoli, so I continued, thinking it must be coming up soon. It was only when I arrived in the conglomeration of Agios Nikolaos that I realised I'd missed it.
So, now seriously short of time, I ploughed north up the headland, past Elounta and gaining fabulous views of the former leper colony of Spinalonga on the way. After Elounta though, the signposting got very vague, my map didn't seem to correspond and I made several wrong turns. The trick appears to be that if the road is heading in the right direction, take it, and don't mind the signposting.
When I finally got to the last bit of headland itself, it appeared from afar that there was one road going around the base of the cliffs and one over the top. I have no idea if I chose correctly but I went for the latter. A tiny white handpainted sign marked "Ag. Iwonnios 5km" meant I left the road and onto a concrete track. This was okay for a while and gradually disimproved the further I got. Finally when I got to the area of wind turbines, I was starting to have serious concerns for the safety of my car in the huge potholes, so, way behind time, I turned around and headed back for Heraklion, finding the Neapoli road which, I estimate, saved me about an hour!
As it happened, they delayed in Rethymno, so I had another hour, which could easy have seen me walk from the wind turbines to the lighthouse and back, but I wasn't to know.
The picture below shows what I missed.
