Phi-Phi Islands belong to Thailand and they are located between the mainland and the Phuket Island. The largest is the Ko Phi Phi Don Island – it is at the same time the only permanently inhabited island from the Phi-Phi group. The second largest is the Ko Phi Phi Lee Island. Both of the are known for sandy, tropical beaches, which are visited by many tourists. Beautiful beaches, clear water and lime rocks scattered in the sea attract those willing to rest. In 2004 the Phi-Phi Islands were hit by the tsunami. 10-meter waves, caused by the earthquake on the Indian Ocean, heavily damaged the islands.
