Pay Homage to the Ancient Kannimara Teak: Deep within the reserve stands the Kannimara Teak, one of the largest and oldest living teak trees on Earth. Boasting an incredible girth of over 6.5 meters and towering past 48 meters, this prehistoric giant is estimated to be more than 460 years old. Local tribes worship the tree as a living deity, and it was rightfully awarded the Mahavriksha Puraskar by the Government of India for its phenomenal historical value.

Embark on a Multi-Terrain Forest Jungle Safari: To explore the core zones, visitors board the official eco-tourism jungle safaris. Because commercial private vehicles are strictly restricted past the entry gates to maintain low emissions, these specialized vans navigate deep logging tracks. The drives provide elite opportunities to spot the majestic Bengal tiger, wild elephant herds, the Indian Gaur (bison), Nilgiri langurs, and the highly vulnerable Malabar Giant Squirrel leaping through the high tree canopies.

Cruise the Waterways on a Traditional Bamboo Rafting Circuit: For an unforgettable, quiet immersion into the wilderness, take a guided bamboo rafting tour on the calm expanses of the Parambikulam reservoir. Steered expertly by tribal oarsmen using long bamboo poles, the raft drifts silently along the edges of the dense, half-submerged dead woods. This slow-travel experience allows birdwatchers to spot unique water birds like the Lesser Adjutant Stork and the Oriental Darter without scaring them off.

Trek the Pugmark Trails and Stay in Island Nest Eco-Lodges: For multi-day explorers, the Forest Department coordinates specialized guided treks like the Pugmark Trail. Accompanied by tribal trackers, you can decode jungle signs and look for fresh tracks. To experience the ultimate deep-jungle night, book an overnight stay at the Island Nest—a secluded bamboo cottage built directly on an island structure inside the reservoir, accessible only via rowboat.
