They are in the process of putting a sidewalk in along the beach road (on the morass side) but it isn't complete yet. Walking along the beach road can be scary at times, we were almost in the middle of an accident once, but for the most part it's not bad. Always walk facing the traffic... I personally wouldn't walk much at night, but if you do, bring a flashlight. The ground can be uneven at best.

The cliff road on the other hand, is another matter. I'm not a fan of walking up there, but many do. It's narrow and windy and they drive fast... Be aware of what's going on around you...
