Uorullubut kus (Russian: Уоруллубут Кус) is a forest in the western and central part of Megino-Kangalassky Ulus. It covers an area of 21 km2 and is approximately 3 km from Allaraa Besteeh and 5 km from Tyokhtyur. Previously 71% of the forest was pine, but in 2008 a fire caused by man destroyed 61% of the forest area. Since 1989 it has been open to the public. Kyys Timirbit lake lies in the forest, as do numerous rivers.
