This spa is a one with a wild twist and is definitely not for the faint-hearted.

Ada Barak's spa in the north of Israel offers its guests a chance to be massaged by snakes.

Barak, who uses California and Florida King snakes, corn snakes and milk snakes in her treatments, says she was inspired by her belief that once people get over any initial misgivings, they find physical contact with the creatures to be soothing.

During the massage, which costs 300 shekels ($A89.85), Barak releases six non-venomous snakes onto the backs of her customers and allows them to slither around.

It is said that the massage has a therapeutic effect on aching muscles and stiff joints.

"I'm actually afraid of snakes, but the therapeutic effects are really good," customer Liz Cohen told Reuters Television as Barak let the snakes loose on her body.
