Nelapattu Bird Sanctuary, located near Sullurpeta in Andhra Pradesh, is one of South India’s most important wetlands and a prime breeding site for Spot-Billed Pelicans, attracting thousands of migratory birds every winter. Spread across lush freshwater tanks and dense Barringtonia tree forests, the sanctuary offers peaceful walking trails, watchtowers, and a nature interpretation center that helps visitors understand the region’s rich biodiversity. The best time to visit is November to March, when pelicans, storks, egrets, cormorants, and ibises arrive in large colonies. The sanctuary is open from 7:00 AM to 5:00 PM, with early morning and late afternoon offering the best birdwatching and photography opportunities. Just 20 minutes from Pulicat Lake, Nelapattu is perfect for wildlife lovers, families, and weekend explorers looking to experience an unspoiled natural habitat close to Chennai and Tirupati.
