Okhla Bird Sanctuary, located in the Gautam Buddha Nagar (Noida) district of Uttar Pradesh, is a renowned haven for birdwatchers and nature lovers. Situated at the Okhla Barrage on the Yamuna River, right along the Delhi–Noida border, this protected wetland lies just a few kilometers from Noida Sector 95 and is easily accessible from central Noida and South Delhi. The sanctuary is home to over 300 species of resident and migratory birds, especially vibrant during the winter season when birds arrive from Central Asia and Europe. Spread across lush floodplains, marshes, and grasslands, Okhla Bird Sanctuary offers scenic walking trails, watchtowers, and peaceful natural surroundings amid an urban landscape. Its close proximity to Noida city, Kalindi Kunj, and major expressways makes it one of the most popular eco-tourism destinations in western Uttar Pradesh, ideal for photography, weekend outings, and environmental education.
