Among the many such transcendental lovers of the Supreme Personality of Godhead, the gopīs are the best, and among the gopīs Śrīmatī Rādhikā is the best. Śrīmatī Rādhikā is very dear to Lord Kṛṣṇa, and similarly Her ponds, namely, Śyāma-kuṇḍa and Rādhā-kuṇḍa, are also very dear to the Supreme Personality of Godhead.
(CC Adi 7.18-19)

Āriṭ-grāma is also called Ariṣṭa-grāma. Śrī Caitanya Mahāprabhu understood that in that village, Ariṣṭāsura was killed by Śrī Kṛṣṇa. While there, He inquired about Rādhā-kuṇḍa, but no one could tell Him where it was. The brāhmaṇa accompanying Him could also not ascertain its whereabouts. Śrī Caitanya Mahāprabhu could then understand that the holy places known as Rādhā-kuṇḍa and Śyāma-kuṇḍa were at that time lost to everyone’s vision. He therefore discovered Rādhā-kuṇḍa and Śyāma-kuṇḍa, which were two reservoirs of water in two paddy fields. Although there was very little water, Śrī Caitanya Mahāprabhu was omniscient and could understand that formerly these two ponds were called Śrī Rādhā-kuṇḍa and Śyāma-kuṇḍa. In this way Rādhā-kuṇḍa and Śyāma-kuṇḍa were discovered.
(CC Madhya 18.3 purport)

The Lord then understood that the holy place called Rādhā-kuṇḍa was no longer visible. However, being the omniscient Supreme Personality of Godhead, He discovered Rādhā-kuṇḍa and Śyāma-kuṇḍa in two paddy fields. There was only a little water, but He took His bath there.
(CC Madhya 18.5)
