The Edakkal Caves feature a crevice of around 96 feet in length, 30 feet in depth and 22 feet in width. There is a fissure at this site that was created due to splitting of a rock. This fissure and rock walls feature carvings of animal and human figures of the pre-historic era.
The trekking trail to these ancient caves from Edakkal extends around 1 km. Trekking is possible through Ambukuthi Hills to travel to these Edakkal Caves. The trekking route is covered with coffee plantations and takes around 45 minutes to climb up the hills.
There is a telescope near these caves that are used for seeing the surrounding valley. Recent findings state that these caves were once related to the Indus Valley Civilisation, where tourists can see around 400 signs, including ‘a man with a jar cup’.
