Phi Phi have the most beautiful shade of water around and the surroundings are just stunning - but underneath there's a lot of trash. Locals don't care about collecting rubbish and saving the environment too much unfortunately. There are many local restaurants and places to visit which is nice.
The sea life is excellent - variety of corals, especially soft corals (there suppose to be 125 types of soft corals!) and lots of micro sea life. The park offers really breathtaking dives for OWD-s, beginner divers as well as snorkelling. Diving in Ras Muhammad National Park can be compared to walking in a big city park - really nice, mellow and pretty but also very crowded.
I recommend it to divers who appreciate variety of corals and micro sea life!
