Thommankuthu Waterfall

Thommankuthu Waterfall (celebrated as the legendary Seven Step Eco Trekking Cascade of Idukki), situated amidst dense semi evergreen Western Ghats rainforests in Karimannoor Vannappuram just 18 km east of Thodupuzha in Kerala, is one of Kerala's most spectacular, pristine, and adventurous wilderness eco tourism destinations.

Named after the fearless tribal hunter 'Thomban' who historically discovered this remote jungle gorge, the perennial Kannadiyaru river cascades down through seven distinct descending rock steps across a 5 kilometer mountain forest tract, creating crystal clear natural plunge pools, swirling whirlpools, and dramatic spray filled cataracts.

It's the home of an exhilarating 12 kilometer guided forest wilderness trekking expedition managed by the Kerala Forest Department and Vana Samrakshana Samithi (VSS), mysterious pre historic rock cut caves where ancient hunter gatherers sheltered, natural deep rock pools for safe swimming and hydrotherapy bathing, swinging bamboo suspension bridges spanning gushing mountain streams, and rich biodiversity sheltering wild elephants, sambar deer, giant Malabar squirrels, and hundreds of rare bird species.

It represents a rich highland sanctuary where raw Western Ghats wilderness, thrilling multi tier waterfall trekking, indigenous tribal folklore, and rejuvenating forest hydrotherapy unite in the high ranges of Idukki district.

Located in Thommankuthu village near Karimannoor, it sits just 18 km from Thodupuzha KSRTC Bus Station, 60 km from Kottayam Railway Station (KTYM), and 65 km from Cochin International Airport (COK), easily accessible by regular town buses, private cabs, and auto rickshaws.

The Seven Step Waterfall System & Deep Plunge Pools

The unique geographical marvel of Thommankuthu is its step wise descent, with each of the seven tiers dropping into a distinct natural rock swimming pool over a 5 km stretch.

The first cascade is easily accessible via paved forest pathways, while reaching the upper six tiers requires an adventurous uphill trek through dense tropical foliage and mossy boulders.

Truth is, dipping into the refreshing, ice cold mountain stream after a hike through the tropical forest canopy provides an incomparable natural rejuvenation.
