By Hemant Sharma A tiger reserve is not just a forest with tigers. It is a living kingdom of rivers, valleys, grasslands, hills, mangroves, tribal communities, prey animals, birds, reptiles and ancient trees. When a tiger reserve becomes bigger, it does not only give more space to the tiger. It also protects water sources, forest corridors, elephant movement, local climate and hundreds of lesser-known species that live under the shadow of the big cat.
India has the world’s strongest wild tiger conservation network. By 2026, India has 58 tiger reserves spread across 18 states, covering about 84,500 sq. km, according to NTCA’s latest tiger-reserve profile booklet. This article ranks the biggest tiger reserves in India by total notified area, including core and buffer zones.
1. Nagarjunsagar-Srisailam Tiger Reserve, Andhra Pradesh
Nagarjunsagar-Srisailam Tiger Reserve is the biggest tiger reserve in India by notified area. Spread across the Nallamala Hills of Andhra Pradesh, it covers around 3,296.31 sq. km as per NTCA’s latest area listing. Older references sometimes mention a larger combined landscape because the historic reserve extended across present-day Andhra Pradesh and Telangana, but in the current tiger-reserve framework, the Andhra Pradesh side and Amrabad in Telangana are counted separately.
The reserve is connected with the Krishna River, deep valleys, dry deciduous forests, rocky terrain and the famous Srisailam temple landscape. Its large size gives tigers wide movement space, but the terrain also makes protection challenging.
- State: Andhra Pradesh
- Total area: 3,296.31 sq. km
- Main landscape: Nallamala Hills and Krishna basin
2. Manas Tiger Reserve, Assam
Manas Tiger Reserve in Assam is one of India’s most beautiful and ecologically rich tiger reserves. It covers around 2,837.10 sq. km, making it the second-biggest tiger reserve in India by total area.

It is also a UNESCO World Heritage Site and is famous for tigers, elephants, rhinos, wild buffalo, golden langurs, pygmy hogs and rich grassland-forest habitats. Its combination of Himalayan foothills, riverine forests and alluvial grasslands makes it one of India’s most valuable wildlife areas.

The reserve is named after the Indravati River, which forms a natural boundary in parts of the landscape. It is known for dense forests, wild buffalo, tigers, leopards, dholes, gaur and rich tribal-cultural surroundings. Security and accessibility issues have often made conservation work difficult here, but its ecological value remains immense.

It is located in Madhya Pradesh and was formed by combining important forest habitats in the central Indian landscape. This reserve has become significant because Madhya Pradesh already holds one of India’s strongest tiger networks.
