-Starting from the park Koordinates you'll see a sign on your left marked 'Ancient Monument', head down this track until you come to a more modern monument (of Yannis Zigdis). What was a path now becomes very stoney and uneven, follow this route until you reach the ancient windmill, looking out for the little stacks of stones that mark the easiest way. The path from here up to the tomb is very uneven so again look out for the stacks of stones to guide you on the way up. Thank you very much Gatoulis for maintenance!
-Wearing sensible shoes and of course there's no shops out here so you'll need to take a bottle of water.
