Walvis Bay to Swakopmund is a half hour drive, but we only got there at 2pm due to the fact that the car's battery was flat (most likely due to the fact that Brig left the lights on the night before - what a dumb car to not switch them off when you lock it - our cars do!).
We booked a quad bike tour for the next morning and then went for sundowners at the Tug Restaurant next to the Swakopmund jetty and, after walking out along the jetty, enjoyed watching a beautiful sunset .
