Starting from the most southern suburb of Athens, you follow the coast all the way to Sounio. Here you will find the temple of Poseidon!
From here you will follow the road to Lavrio, we recommend to have a coffee here by the seaside!
Right after the town of Lavrio there is a small climb, followed by a road through the vineyards. Soon you will ride into the town of Keratea where you start the climb onto Keratovouni. Where on the summit of the mountain you'll find a abandoned military base!
From there you will descend back down and will follow calm roads until you get back to the coastal road.
