Visit the famous Tirumala Balaji Temple, one of the holiest pilgrimage sites in India. The temple opens at 3:00 AM and sees heavy queues, so morning darshan is ideal for a spiritual experience.
Head to Talakona Waterfalls, about 50 km from Tirupati, famous for its scenic beauty and trekking trails through the forest. The park opens by 6 AM and closes by 6 PM.
