The countryside around the Haubi area, east of Kondoa, has been devastated by erosion on a scale dramatic enough to attract visitors in its own right. Huge gullies — badlands in miniature, with knife-edged ridges, red earth amphitheatres, and orange ravines — scar the hillsides in a landscape that manages to be both beautiful and sobering. Standing at the rim of the largest gully you can look across to eroded pillars and ridgelines that would not be out of place in the American Southwest.
To reach the best viewpoints, turn east at Gubali village onto a rough track that requires a four-wheel drive vehicle. The Haubi Catholic mission, a solid colonial-era establishment, can provide local guidance and sometimes basic hospitality if you are stuck or planning a longer stay in the hills. The mission itself is worth a look: an imposing brick building set among planted trees that offers a cooler resting spot than the open ridges.
Come in the dry season (June to October) if you can — the roads become treacherous in rain and the gullies actively widen during heavy downpours, which is both dangerous and fascinating to witness from a safe distance.
