I always park in the same place Meleri and it's at the shortest distance to Angel Bay. At the bottom of the Penrhyn Bay hill take the road to Rhos on Sea Golf Course.
After a short distance take the first left after the Garage, then turn right and keep on that road. It then goes along Penrhyn Beach East, at the far end there is a cul du sac and park there.
Just drive carefully when you get to that cul du sac as the traffic on the left has right of way
Once you have parked up go to the head of the cul du sac, you'll see the steps ahead so go up there and at the top turn right and follow the path all the way to Angel Bay. Hope that you enjoy your visit to there.
