Ananthapura Lake Temple located at a distance of 30kms from Bekal in the Kasargod district, is the only lake temple in Kerala. The beautigul lake temple is regarded as the 'Moolasthanam' (original seat) of Anathapadmanabha, the diety of Padmanabhaswamy temple, Thiruvananthapuram.
The presiding of the temple is Lord Vishnu seated on the serpent god, Adishesha. The temple is open to all visitors irrespective of caste, creed, and colour. The temple is situated in the centre of the Ananthapura Lake, on a remote rocky hill in a calm isolated region. The temple affords a bird's eye view of the green landscape around.
It is believed by the local people that there is a lone crocodile living in the lake. The shrine is encircled by a 'Chuttambalam' (an enclosed verandah running around the building), its walls are adorned by murals and there is a cave within that opens out to a small pond where the water level remains steady regardless of climatic changes.
