Erigavo (, ), also spelled as Erigabo, is a city administered by Somaliland and the largest administrative center in the Sanaag region. Variant English renderings of the town's Somali name (e.g. Ceerigaabo/Ceerigabo) reflect differences in romanization conventions for Somali long vowels and consonants noted in recent linguistic guidance.

to the north of the town are remnant juniper woodlands that form part of the northern escarpment forests fringing the Sanaag highlands, within the Somali montane xeric woodlands ecoregion. The escarpment forms a sharp drop to the Gulf of Aden coastal plain, reaching around in elevation before descending toward the coast, a pattern typical of the northern ranges where upland catchments drain to the Gulf. to the west, the massif rises to Shimbiris (Mount Shimbiris), the highest point in Somaliland at about above sea level. A road from Erigavo also leads onto the Daallo plateau/Daallo escarpment, part of a long-recognized forest belt; the Daallo Important Bird Area supports evergreen forest dominated by Juniperus procera and Olea on the rocky scarp. The nearby ancient coastal settlement of Heis (Xiis) has been the subject of recent archaeological missions documenting its role in Red Sea trade networks.
Erigavo's uplands and the Daallo–Shimbiris escarpment host characteristic fauna of the North Somali mountains. Avifauna of conservation interest includes the endemic Warsangli linnet and other high-elevation species recorded in juniper woodland around Daallo.
Climate
Under the Köppen climate classification, the Erigavo highlands have a mild semi-arid regime shaped by elevation, with warm days and cool to cold nights and without extreme heat typical of lowland arid zones; seasonal rainfall follows the Gu (April–June) and Deyr (October–November) peaks common to northern Somalia/Somaliland.
Station data compiled by the Deutscher Wetterdienst (DWD) indicate long-term average annual precipitation of about at Erigavo, with the wettest months in the main rains and very dry conditions in boreal winter; temperatures are equable year-round and sub-zero minima have been observed in some months. The town's altitude on the Sanaag escarpment keeps mean monthly temperatures in the mid-teens to around and sharply limits very hot days relative to coastal and inland lowlands.
