The monsoon in India isn’t just about hills and waterfalls—it’s also a spectacular time for wildlife. While many tiger reserves and national parks close from June to September, several key sanctuaries across the country remain open and offer a completely different perspective of the wild. Lush landscapes, newborn animals, fewer tourists, and the symphony of rain make it a magical season for nature lovers.
In this guide, we highlight top wildlife sanctuaries and national parks open during monsoon, covering where to go, what to expect, and how to plan your trip responsibly.
1. Periyar Wildlife Sanctuary, Kerala
Nestled in the Western Ghats, Periyar Wildlife Sanctuary in Thekkady is open year-round and especially stunning during the monsoon. The Periyar Lake fills to the brim, the forests turn an even deeper green, and boat safaris offer tranquil sightings of elephants, gaurs, and macaques on the banks.
While jeep safaris are limited during heavy rainfall, nature walks, bamboo rafting, and boat cruises continue and offer immersive experiences.
Pair this destination with a visit to Kumarakom or Munnar, both of which are monsoon-friendly hill escapes. You can check out our Kumarakom travel guide or Munnar in March to extend your Kerala itinerary. Periyar National Park Guide for Nature Lovers

2. Kaziranga National Park (Eastern Range), Assam
While parts of Kaziranga are closed during peak monsoon, the Eastern Range (Agratoli) remains partially accessible depending on water levels and conditions. This area is rich in birdlife and offers views of the floodplain ecosystem—a spectacle unique to Assam during rains.
Kaziranga is home to the Indian one-horned rhinoceros, and during monsoon, the rhinos and elephants are often seen along elevated areas near the park. While jeep safaris may be restricted, buffer zones and community conservation areas remain open for eco-tourism.

3. Silent Valley National Park, Kerala
Tucked deep in the Nilgiris, Silent Valley National Park remains open through the monsoon and offers an extraordinary rainforest experience. Unlike typical tiger reserves, this park is famed for its undisturbed biodiversity, including the Lion-tailed macaque, Nilgiri langur, and countless orchid and insect species.
The heavy rains of July and August only heighten the mystery of the place. Treks and guided walks are available but require advance booking with forest authorities. You’ll need to take a forest vehicle from the buffer zone, making it a true wilderness journey.
Best time to visit: June to September
Ideal for: Eco-tourists, biology students, serious nature enthusiasts
4. Mhadei Wildlife Sanctuary, Goa
While most tourists head to Goa for its beaches, Mhadei Wildlife Sanctuary in the northern part of the state is a paradise for monsoon adventurers. Known for its dense forests, rare species like the black panther, and spectacular monsoon waterfalls, the sanctuary offers unique sightings during the rains.
Trekking, birdwatching, and butterfly spotting are popular activities here. Plus, Goa’s spice plantations and monsoon festivals (like Sao Joao) complement a nature-filled itinerary beautifully.

5. Cotigao Wildlife Sanctuary, South Goa
Another monsoon-friendly sanctuary in Goa is Cotigao, located near Canacona. Less crowded than Mhadei, it features treetop watchtowers, wet evergreen forests, and plenty of birdlife. It’s ideal for families and beginner wildlife enthusiasts.
Cotigao is home to deer, giant squirrels, and reptiles, and the rainforest ecosystem becomes especially active during the monsoon. This is a great add-on to a beach-and-jungle itinerary if you’re looking for variety.
Best time to visit: June to September
Ideal for: Family nature tours, Goa road trips
6. Agumbe Rainforest, Karnataka
Known as the Cherrapunji of the South, Agumbe is one of India’s best places to experience rainforest wildlife during monsoon. Though it’s not a national park in the formal sense, this protected rainforest zone is a hotspot for king cobras, giant squirrels, and rare amphibians.
Agumbe is part of the Someshwara Wildlife Sanctuary and is open year-round. The monsoon brings out the true biodiversity of the Western Ghats, making it a dream destination for herpetologists and serious nature lovers.

You may spot elephants, gaur, and a variety of birds along the riverbanks. The lush surroundings, mist-covered jungle, and dramatic skies make monsoon a spectacular time for photographers and those seeking a more relaxed wildlife vacation.
Best time to visit: July to September
Ideal for: Luxury wildlife travel, birdwatching, honeymooners
8. Chilika Lake, Odisha
While not a forested wildlife sanctuary, Chilika Lake—Asia’s largest brackish lagoon—is a haven for biodiversity even during the monsoon. While the major bird migration happens in winter, the rainy season brings lush greenery, rich fish life, and dolphin sightings near Satapada.
Boat rides continue in many parts of the lake, and local fishers offer eco-friendly tours. For travelers exploring Odisha during Rath Yatra or Puri cultural visits, Chilika makes for an excellent add-on.
