Perched on the jagged rim of the crater, wreathed in morning mist, camouflaged in river-stone and cloaked in indigenous creepers, the Ngorongoro Serena Safari Lodge is a triumph of ecological and architectural fusion. Sensitively constructed so as to take nothing from its environment whilst affording endless vistas over the heat-shimmering reaches of the crater below, the clustered boulder-built buildings of the Lodge hug the crater rim, linked by rope-lashed timber walkways that skirt the buttressed roots of ancient, liana-hung trees.
