Out of the airport (only one way to go) turn right at the junction, follow the road to the sea, Turn left and follow road round keeping sea on your right, past the old fort on right take first right at the end of the cricket green (on the left) again you will see the sea on your right, follow the road past the port, all on your right hand side, you will come to a junction with traffic lights, again turn right onto a dual carriageway, follow this road, you will come to Kontokali, then Gouvia, at the end of the dual carriageway ( it stops for a short while when you get to Kondokali (when you run out of sea on your right)) you come to the Tzavros Crossing, just a set of traffic lights with a direction to Dassia to the right, GO STRAIGHT ON at this point,signed Paleokastritsa, at the next major junction (no traffic lights) take the right turn signed either Sidari, Roda or Acharavi, Skripero, (sorry cant be exact.) follow this road through Skripero, then all the way to Troumpeta, when you start to go down hill, after a couple of snaky bends take the right turn (almost back on yourself) past the quarry, after about 10 minutes you come to a junction whith signs for Acharavi both staight on and also to the left, take the left hand turning, follow this road for about 6-8 minutes when you will see a sign for Roda and Acharavi to the right, just follow this road to the T junction, turn left and immediatly right at the Traffic lights for Acharavi. When you reach Acharavi go right through the town.
This is the route that all the taxis and coaches take as it is the most direct.
I would assume that you have detailed directions to your accomodation from Acharavi. Almiros is to the East of town.
Enjoy your stay.
