Edakkal cave is 25 km from Kalpetta and just 3 km from Ambalavayal. It is a crevice of about 96 ft in length and 22 ft width. A fissure was created by a rock splitting due to natural weathering. The depth of the crevice and the fissure is nearly 30ft., giving an appearance of a cave to any observer.
There are human and animal figure carvings on the rock walls, depicting images of pre-historic periods and rather civilized people.
The caves can be approached by a 1km trekking trail starting from Edakkal. The best visiting hours are in the morning; though the cave is open till 5 pm. Tourists need to indulge in a one and half hour long trek to reach the entrance of the caves. The roads are in good condition. In order to reach the actual cave, tourists will have to trek uphill for another 45 minutes.
