- The bedrock of the Simien Mountains comprises a vast and ancient basaltic dome moulded into a series of jagged pinnacles and buttresses by glacial activity and precipitation. More than a dozen of its peaks top the 4,000m mark, including the 4,533m Ras Dejen, which is Ethiopia’s tallest mountain.
- The Afromontane vegetation of the Simien Mountains includes more than 1,200 plant species, of which three are endemic to the national park. Above 3,700m, the dominant vegetation type is open grassland punctuated by spectacular giant lobelias that stand up to 10m high. Giant heather trees and other ericaceous plants are the main vegetation type between the 3,000m and 3,700m contour.
- Simien protects an alluring selection of endemic wildlife. It is the last remaining stronghold of the impressively horned Walia ibex, the only goat indigenous to sub-Saharan Africa. Large troops of gelada baboon are rendered unmistakable by the male’s flowing lion-like mane and heart-shaped red chest patch. A population of around 50 Ethiopian wolves is the world’s second-largest after Bale Mountains National Park. Other large mammals include Anubis baboon, Hamadryas baboon, grivet monkey, Menelik’s bushbuck, klipspringer, common jackal, spotted hyena, and leopard.
- Simien Mountains National Park is one of northern Ethiopia’s key birding sites, with a checklist of 180 species that includes five Ethiopian endemics and 12 near-endemics. However, many would say the true avian star of the Simien is the magnificent lammergeyer, a cliff-loving vulture with a 2-meter wingspan and the only bird in the world with a specialized diet of bone marrow.
- The best way to explore the Simien Mountains is on foot or mule back Several overnight options are available. The 3-day trial connecting Sankaber, Gich, Imet Gogo, and Ayna Meda is recommended to those whose main interest is endemic wildlife. For peak-baggers, the ascent to the summit of Ras Dejen could be undertaken as a 3-day hike from Chennek. For those with limited time, it is possible to drive east from Debark to Chennek along an all-weather road and to exit the car for short walks.
