I have been there many times. An ancient temple believed to be built by Guru and VAYU( God). The temple is well maintained, decorated and the power of the deity is huge, and it will reflect in your life. It is a temple dedicated to Lord Sree Krishna.
Only Hindus are allowed, with a traditional clothing. that is dothi for men( no shirt) and saree or panjabi dress for ladies. There are many elephants inside the temple, and the night procession of the elephants carrying the deity is simply super and if your are a hindu, dont forget to visit this temple. The prasadam is also tasty and there is a free meal prasadam for lunch for all the devotees. The nearest railway station is Thrissur and Airport is Cochin.
