The Edakkal Caves are a natural rock formation on the Ambukuthi hills in southern Wayanad, containing petroglyphs (rock engravings) that date back to the Neolithic and later periods. The "cave" is really a large rock shelter formed by a massive boulder wedged between two vertical walls of rock, creating a chamber about 30m long. The carvings on the walls cover a range of styles and periods, from simple geometric forms to complex figurative images.
The site is reached by a 45-minute uphill walk from the road, with good views over the surrounding hills on the way up. It can be busy at weekends and during school holidays; early morning visits are calmer and cooler. Entry tickets are available at the base. There is no lighting inside so bring a torch; guides are available but optional. The site is closed on Mondays.
