As it is free of [[Schistosomiasis|Bilharzia]] (schistosomiasis), unlike all other freshwater lakes in Ethiopia, Lake Langano is popular with tourists and city-dwellers. The lake is brown in colour and at first sight one may think that the lake is not clean. However this is not the case, the reason for the colour is due to the richness of minerals including high sulphur levels which have led many to believe that the lake water has healing properties. There are a number of resorts around the lake and water sports are popular. There is a variety of wildlife around the lake, which include [[Hippopotamus|hippos]] (rare), [[monkeys]], [[baboon]]s, [[warthogs]], and a huge variety of birds. The area around the lake is largely deforested, however, and a large number of herders live around the area.
Two earthquakes had their [[epicenter]] near this lake, the first in 1906 (a magnitude 6.8 on the Richter scale), and the second in 1985 (magnitude 6.2).<ref>[http://www.mediaethiopia.com/Engineering/EarthquakeHazard_ET.htm "Earthquake Risks in Addis Ababa and other Major Ethiopian Cities – Will the Country be Caught Off-guarded?"] {{Webarchive|url=https://web.archive.org/web/20100225123630/http://www.mediaethiopia.com/Engineering/EarthquakeHazard_ET.htm |date=2010-02-25 }} by Dr. Samuel Kinde, published March 2002 (accessed 4 June 2008)</ref> After the earthquake of 1906 there formed a 25–30 m tall geyser on Edo Laki Island on the northern part of the lake. The geyser disappeared circa 1966 – 1970, leaving a hot spring.
