Sundarbans Tiger Reserve

Beta

Also known as Sundarbans National Park

Plan your visit

Winter offers clearer skies and safer boat conditions for exploring creeks and watchtowers; early winter may coincide with bird migrations and active fish-based foraging by tigers and dolphins.

Zones
Boat-based tourism circuits in Sundarbans Tiger Reserve and National Park
Safari
boat safaris on tidal rivers and creeks, with viewing from decks and watchtowers
Typical sightings
Spotted deer on mudflats, crocodiles basking on creek banks, raptors over channels and, with luck, tigers on banks or swimming.
Light and terrain
Strong glare from water and bright skies requires careful exposure; mist and haze can soften early-morning views; long distances are often involved.
Hides
Watchtowers on select forested islands; no ground-walk hides in core mangrove blocks.
Good to know
Movement restricted to authorised boats and designated landing points; no walking safaris in the core; tourism subject to tidal schedules and weather advisories.
