Do NOT use the directions on Google Maps, as that route has not been maintained since 2012 and the section just before they say "Sharp right" is impassable for small vehicles and trailers. Rather proceed to, and through, Coffee Bay to Hole in the Wall, or turn-off the tar road at Ngcwanguba.
Hole in the Wall is very safe. Probably the safest village on the Wild Coast, as there are security patrols active day and night.
Unfortunately, unemployment is a major problem. So please do not be put off by youths who will want to "guide" you to the Hole in the Wall. Simply, and firmly, say "No thank you".
The youths will also crowd around your vehicle at the parking site - clamouring to "guard your car". It is advisable to select one at random and offer to pay R5 per hour.
