The word vana means “forest.” Vṛndāvana is the name given to the forest where Śrīmatī Vṛndādevī (Tulasīdevī) grows profusely. Actually it is not a forest as we ordinarily consider a forest because it is very thick with green vegetation. There are twelve such vanas in Vṛndāvana. Some are located on the western side of the Yamunā and others on the eastern side. The forests situated on the eastern side are Bhadravana, Bilvavana, Lauhavana, Bhāṇḍīravana and Mahāvana. On the western side are Madhuvana, Tālavana, Kumudavana, Bahulāvana, Kāmyavana, Khadiravana and Vṛndāvana. These are the twelve forests of the Vṛndāvana area.
In Kāmyavana, Kṛṣṇa performed enchanting pastimes. Here you will be able to take darśana of many ponds and other transcendental spots.
