No special access issues
From Massouri, head towards Kasteli until the road bends around the stone walls of a house, then you'll see a steep paved concrete road on the right. If you're driving a car or scooter, continue past the concrete road to find a safe spot to turn around, then head up the ramp (a bit of momentum is needed). Once the road levels out, find a safe place to park without impeding local traffic, and follow the painted markers and cairns past North Cape towards the school. It's possible to reach the Aegean Sea wall this way, but it's much easier to continue along this road until you reach the parking below the large boulder where the trail to Odyssey starts. Park considerately for the residents. Walk up the trail to Odyssey, traverse left along the crag past all the routes to the end, and then follow the markers for another five minutes.
