We walk the beach at night but have never done it alone. The larger the group the less concern I have. We always stay aware of our surroundings. If we don't feel comfortable we walk faster until we get to an area with others present. I have personally found we are not hassled as much if we are walking at the shoreline instead of up on the beach. If we are with someone that doesn't or can't move very fast we would walk along the road.
