If witnessing rituals in a 2000 years old temple sounds like a fascinating idea, you just cannot skip a visit to Janardhana Swamy Temple. An architectural masterpiece in Varkala, it sees prayer ceremonies four times a day, held by the head priest. Devotees throng to the huge water tank inside the complex for a dip after the rituals. Evening arti in the temple is an impressive, elaborate offer as well. While the temple is open to everyone, remember to wear fully-covered clothes and head scarf in the inner sanctum.
