SB 9.1.25
sukumara-vanam meror
adhastat pravivesa ha
yatraste bhagavañ charvo
ramamanah sahomaya
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There in the north, at the bottom of Mount Meru, is a forest known as Sukumara where Lord Siva always enjoys with Uma. Sudyumna entered that forest.
