A full day covering the city's compact historic core, including Christuskirche (the German-colonial-era church that's become one of the city's most recognizable landmarks), the National Museum, and an art gallery.
A camping and stargazing night just outside the city — spent in the company of a German family met along the way. A genuinely easy way to get a wildlife-and-wilderness taste without leaving the Windhoek area.
TaTe Village BackPacker — described in the trip's own record as "home away from home," used both on arrival and again on the return leg before departing via Ethiopian Airlines toward Addis Ababa. NAD 550.24 (~$32) for a 2-night dorm bed.
The Drum Cafe came up as the standout "one fun thing to do in Windhoek." An evening was also spent at Matargasti.
