Sesreim two gate entry system
The national park gate which you access from the main road D826 (north from Windhoek) and C27 (south) gravel roads referred to as “Sesriem gate” opens at sunrise and closes at sunset (blue on the map) while the second gate (red on the map) which allows access into the desert opens 1 hour before sunrise and closes 1 hour after sunset.
